The Perseid Meteor Shower
Tomorrow afternoon, I'm driving out to Western Massachusetts to find some dark sky to watch and photograph the Perseid meteor shower. It takes a lot of preparation for me to do this and I thought it might be interesting to share with you how I go about it. Of course, you can just take a camera and tripod and go, but I find I need more information than that.
 
This trip will be pretty interesting, I think, because I have no less than three cameras to record the event: film, digital and infrared. The atmospheric conditions are extremely favorable as well. There is no moon Sunday night and the weather looks to be favorable: high pressure, clear and not much cloud cover.
The first thing I do is figure out when and where the sun and moon will be. This is easy to do via the U. S. Naval Observatory site. Here's the data from Sunday and Monday (edited for readability).

Sunday, August 12, 2007, Eastern Daylight Time

SUN

Sunset                7:58 p.m.

End civil twilight    8:28 p.m.

Begin civil twilight  5:26 a.m. (Monday)

Sunrise               5:56 a.m. (Monday)

MOON

Moonset               8:01 p.m.

Moonrise              6:29 a.m. (Monday)

The moon data is the important stuff here and its relationship to the Sun. Without going into all the stuff I've written about photographing the moon, let me summarize by saying that the best time to take pictures of the moon is usually during sunrise, sunset or twilight. In these conditions, the contrast is much lower between the moon and the sky and the photos tend to look really good. But tomorrow is different because there is a new moon on Monday.
 
The new moon is not visible until the sun hits it and creates a crescent. Likewise, the old moon is a shrinking crescent leading up to the new moon. That all sounds well and good, except you can't see a really thin crescent with the naked eye. In fact, trying to shoot the 'newest moon' or thinnest crescent is extremely difficult. But I'm not here to shoot the moon, I'm here to shoot meteors. For that purpose, I need to know when to be in place to have time to set up before the ambient light drops to the point where a meteor strike is visible. With sunset at around 8 p.m., I'll probably plan a six or six thirty setup. The Perseid's don't technically start until around 10 p.m., but of course, it doesn't really work that way. That just means the statistical bulk of the meteors will occur starting at that time. There are outlyers that happen before and after that.
 
If I were out to watch a satellite or the International Space Station, things would be very different. These objects run across the sky in just a few minutes and then it's over. In order to photograph them, you need to use compass directions and elevation and stuff. Meteors are quite a bit easier, in a way.
 
In a meteor shower, the meteors may appear all over the sky, but if they are part of the actual shower (the Perseids in this case), they will have an origin that can be traced back the radiant. The radient is essentially the direction in which the meteors are flying. So, for example, if you traced the path of the meteor back in the direction it came, it would point to a single area that is the source of the meteors (the debris in the tail of a comet, in this case). Now there can be other random meteors that occur, but these won't generally line up with the radiant.
 
In terms of my preparation, I'm bringing three cameras that I can train on the sky all night long: an infrared Canon G3 that I will shoot automatically with the intervalometer, a manual camera with film for super wide-angle slides and a digital camera for taking shots in real time. What I mean by that is that the film camera will be taking long, multi-minute exposures and the infrared camera will automatically take a series of four or five minute exposures. The digital camera is the one I'll be moving around with and trying to do interesting stuff with. But frankly, it will probably spend a lot of time taking long exposures also. There's little point in trying to shoot a meteor once you see it, for obvious reasons. So you have to train the camera on the sky and shoot pictures hoping a meteor runs through the shot.
 
Hopefully, in a few days, you will start to see the results of my efforts. For now, though, I have to get some tunes going in my car. That's almost as important as buying the film :^).

A Little Balance on behalf of the New England Baptist Church
I wrote a piece this week on the Boston Globe coverage of the New England Baptist Church marquee. The gist of the piece was that the signs are often provocative or offensive and I was a little critical of the Globe for not showing any photos or listing more of the actual contents. So today, I drove by the Church to see what was up on the marquee and I present it to you now.
 
NEBCSignBridge.jpg
 
Now I suppose you could argue that since this wasn't a natural disaster the sign is good and supportive. However, I'm not going get into intent here, I'm showing it for balance in my own coverage of the sign.

For Fun: Dweezil Zappa
Having just blogged about Frank Zappa, it's time now to turn our attention to Dweezil, Frank's son. From what I've seen, Dweezil had a very complicated relationship with Frank. Frank Zappa died young and it must have been devastating for Dweezil. But Dweezil is an excellent guitarist in his own right. He played and recorded with his father a number of times and has also toured playing his father's music.
 
This clip is really interesting if you are a guitarist, which I am. This is actually a demo from a convention - I'm including it to show you both how good he is (watch him play part of Eddie Van Halen's Eruption without even breaking a sweat) and to talk about the sounds he's creating.
 
As a guitarist, I have always been kindof a purist. I don't like long effects chains or unusual processing as a rule. But Frank and to a larger extent, Dweezil, have changed my mind on that a bit. Dweezil is demonstrating a software product that will recreate not only the sound but the ambience of a performance. Thus he can sound exactly like Eddie Van Halen or Angus Young or whomever and play right over the album and sound like he was actually in the studio recording. It demonstrated to me that audio signal processing technology is at the point where I need to take a more serious look at it.

 
 
I hope you enjoyed Dweezil messing around on his guitar. By the way, the solos he's playing at the beginning and end are played over the Frank Zappa tune, Inca Roads. This is a very unusual composition and a favorite amongst Zappa devotees. There isn't a really good clip on Youtube for it, but if you are brave, you can check out this performance with some really freaky scary claymation in the middle of it (WARNING: not for the young or weak of heart).

For Fun: Frank Zappa
I've been a longtime fan of Frank Zappa. He was an excellent guitar player, soloist, composer, arranger and generally wierd guy. Let me introduce you to Frank Zappa via an interview on the Mike Douglas show from 1976:
Mike Douglas: My next guest is an innovative and unique musician who has created his own style of music ever since he first got his group the, The Mothers of Invention together back in 1964. When he had that group he put out some albums, ah, with bizarre titles like Hot Rats, We're Only In It For The Money, Weasel's Ripped My Flesh and Lumpy Gravy - all love songs. Today he's here to talk about his, his brand new group and his new album called Zoot Allures. Here is Frank Zappa.
 
[Applause]
 
Mike Douglas: [garbled] ... You've got some real fans here, they stood up when you came ... those are very unusual titles, how do you come up with titles like that Frank?
 
Frank Zappa: I'm abnormal.
 
Mike Douglas: [laughs] then it's easy for you?
 
Frank Zappa: Yeah, it's just an everyday thing.
 
[omitted for brevity]
 
Mike Douglas: How long have you been into the rock music?
 
Frank Zappa: Umm, since I was fifteen. I'm thirty five now, so that's a while.
 
Mike Douglas: How did you first tune, tune into it - who'd you start listening to?
 
Frank Zappa: ...used to listen to rythym and blues records...
 
Mike Douglas: Ah. Anybody in particular that really reached you at that time?
 
Frank Zappa: Well I used to ... in those days I used to really like Johnny Guitar Watson and Clarence Gatemouth Brown and Howling Wolf, guys like that. You know, all the old favorites.
At this point, the co-host, Jimmy 'JJ' Walker lets out a big 'hah-ha-ha', having gotten the joke. Mike Douglas was doing the serious head nod agreement with Frank, but immediately moves on making it appear that he really doesn't know what Frank is talking about. Nobody else did, except perhaps the band, but we can't hear them. So the audience is sort of uncomfortably not into it, but they laugh when JJ laughs. The societal undertone here is intense. Here's a white, self-described 'abnormal' musician talking about his influences being black R&B guitarists that the (presumably) mostly white audience has probably never heard of. After the laugh, Frank looks back and forth at JJ a few times with a kind of knowing look, but JJ doesn't reciprocate.
 
The reason the audience laughed when JJ laughed, aside from the release of tension of the moment, is because JJ was extremely famous at that point as the runaway star of Good Times.  He even had a signature catch-phrase, 'Dyn-O-Mite'. People used to laugh even just seeing him. But that's ancient history. Let's move on.
 
The reason I brought up this example is that Frank Zappa was extremely intelligent person, a passionate advocate of free speech and pretty ahead of his time. Fast forward with me now to 1985. Do you remember Tipper Gore? Of course you do, she's married to Al Gore. But in 1985, Tipper and a bunch of other senator's wives founded the Parents Music Resource Center (PMRC), who's goal was to ostensibly protect children by censoring music that was deemed inappropriate. Frank, as a vocal proponent of free speech and a musician with lots of obscene material published, was called to the Senate to testify against the PMRC's legislation. In a classic line from his opening statement, Frank describes the issue bluntly:
It is my understanding that, in law, First Amendment issues are decided with a preference for the least restrictive alternative. In this context, the PMRC's demands are the equivalent of treating dandruff by decapitation.
Frank is very quotable.
 
OK, so enough of the intro, let's get to some music. Although many people have heard some of the popular Zappa songs, like Joe's Garage, Valley Girl, and Don't Eat The Yellow Snow, I've chosen Cosmik Debris. It's basically a blues tune that's pretty accessible (i.e., not too wierd and Zappa-like). By the way, Frank Zappa was fervently anti-drug and even kicked out members of the band if he found them using. This song has a pretty recognizable anti-drug message in it.
 

OK, so now that you've gotten some basic Zappa under your belt, try this one, Montana. This is a song that's got appeal to the more serious Zappa listener - much more complex music and a very strange story-line. I really like this clip because there are several minutes of onstage banter before the music starts and you get a chance to see Frank interacting with the audience. This is not one of the better line up of musicians. Frank had a lot of really talented people playing for him over the years, including Steve Vai, George Duke, Terry Bozzio (although I think he was kicked out for drugs) and others.


And there you have it. You rocked, Frank, rest in peace.

The Globe Discovers Medford's New England Baptist Church
I read with some amusement today this story in the local section of the Boston Globe. They must have been reading Mostly Harmless, because I covered this very same topic years ago. The article concerns the 'provocative or offensive', as the Globe headlines put it, messages posted on the signboard outside of the New England Baptist church in Medford Square. An excerpt:

Some have been more provocative than others. In September 2005, as the city of New Orleans struggled to cope with the ravages of Hurricane Katrina, the church posted, "New Orleans: Natural disaster? Or God's anger with sin?"

Then, as the war on terror raged in Iraq, a sign went up that many people thought insulted members of the American military. While they remember their reaction to that post, no one could recall its exact wording.

By the way, the war on terror is still 'raging', but more importantly I find it amazing that the latter example was so strong and offensive and yet nobody could remember exactly why. Despite listing only three examples in the article, the Globe goes on to say that people are now posting pictures of the signs on the Internet. But they don't actually tell you where, so I checked. I went ten pages into google on two different searches, and frankly, short of the Boston Globe and the Boston Herald, the only site I found was this one.

So this is all getting a little silly for me. Look, the church has a first amendment right to free speech, even in these days of declining civil liberties in the United States. But I would like to see at least a picture or more examples. Failing that, I'll have to take matters into my own hands. Here are two photos I previously published of the New England Baptist Church sign. The first is from when the Democratic Convention was in Boston (I blogged the Medford impact) and the second was from later in 2004, I believe.

As much as I disagree with what they say, I have to tell you that I get the point that's trying to be made. And that should be all there is to it.

Baby Einstein? NOT!
Do you remember the 2007 State of the Union (SOTU) address by President Bush? I do. One moment really stuck out for me. It was during the time in the SOTU when the President recognizes people for their acheivements. For my non-American friends, here's how it works.
 
It has been a tradition for some time for the President (whomever it is, not just Bush) to invite special guests to the vistor's gallery and then praise them publicly for their contribution to the country, society, etc. Here's how President Bush introduced this part of the SOTU in January:

When America serves others in this way, we show the strength and generosity of our country. These deeds reflect the character of our people. The greatest strength we have is the heroic kindness, courage, and self-sacrifice of the American people. You see this spirit often if you know where to look -- and tonight we need only look above to the gallery.

Bush goes on to praise Dikembe Mutombo (Congolese immigrant now a star basketball player for the Houston Rockets), Wesley Autry (private citizen who saved a man who had fallen on train tracks), Tommy Rieman (soldier and Silver Star recipient for heroism) and Julie Aigner-Clark (founder of Baby Einstein).

It's Baby Einstein I have a problem with, but I'll get to that in a moment. Here's what Bush said about Julie:

After her daughter was born, Julie Aigner-Clark searched for ways to share her love of music and art with her child. So she borrowed some equipment, and began filming children's videos in her basement. The Baby Einstein Company was born, and in just five years her business grew to more than $20 million in sales. In November 2001, Julie sold Baby Einstein to the Walt Disney Company, and with her help Baby Einstein has grown into a $200 million business. Julie represents the great enterprising spirit of America. And she is using her success to help others -- producing child safety videos with John Walsh of the National Center for Missing and Exploited Children. Julie says of her new project: "I believe it's the most important thing that I have ever done. I believe that children have the right to live in a world that is safe." And so tonight, we are pleased to welcome this talented business entrepreneur and generous social entrepreneur -- Julie Aigner-Clark. (Applause.)

The backstory here is that the Bush administration, in my opinion, tends to side with whatever will support the growth of companies not matter what the social or financial implications are. And so ironically, the praise was maybe appropriate for Bush even though it seems misplaced. My main complaint is why he chose this company. And it seems clear to me that it's for purely publicity reasons. He wanted to laud a woman entreprenuer with a product that leaves a very healthy, strong impression in the audience. But in trying to reinforce this in the SOTU, Bush made a mistake because these videos do not appear to work. Indeed, the American Academy of Pediatrics is very clear on their recommendations for what kids under 24 months old should watch on TV: nothing.

The American Academy of Pediatrics recommends no more than one to two hours of quality TV and videos a day for older children and no screen time for children under the age of 2. [emphasis added]

Now there must be a reason for that, and we'll get to it in a moment. First, savor the hypocracy of a President praising the character of a business-women who is marketing videos to worried parents who's kids should not watch them. The product exploits every parents' fear of educating their kids: watch Baby Einstein for an hour a day and your kid will be smart. The problem is, it's not true and the opposite might happen. There is now evidence to suggest that these videos make your children dumber.

Today, the results of a study of this very issue were published and they are disturbing. SeattlePI has a more in-depth story. Here's the money quote from the LA Times:

For every hour a day that babies 8 to 16 months old were shown such popular series as "Brainy Baby" or "Baby Einstein," they knew six to eight fewer words than other children, the study found. [emphasis added]

This doesn't appear to be a fluffy study - there were 1,000 infants involved. Although that specific data was not available when Bush made his SOTU in January, my understanding of the issue at that time was that there was significant concern about these videos and no scientific basis to believe they would work as advertised; the APA guidelines were already in place at that point.  In fact, the SeattlePI points out that the FTC is considering false advertising charges against this class of product for exactly this reason. That puts a little tarnish on the SOTU, doesn't it?

UFO Animation
OK here's the deal. I saw a UFO the other day - figured it was a scientific balloon.  I now think it was a balloon. Maybe a bunch of them. But I can't really be sure. What I did was to take the six photos I shot, in fairly rapid sucession (two brackets of three photos, maybe 2 frames per second or a bit over) and animate them in Photoshop. And now you, proud readers, can witness the strange object I saw in the sky over Arlington that day. I remember it like it was yesterday. Actually, it was yesterday. Good day for a wedding, don't you think? That's got to be the leading contender, Occam's Razor style.

Bank Of America Email Scam
Watch out, folks, Ken is out to steal your money...he sent me this email this morning...
 
KenLetter.jpg
 
There are several problems with this letter, the most obvious being that Ken wants your personal information or he'll terminate your account. That is not the way Bank of America would do business. But the domain names are also suspect. Come on, bank-of-america-accounts.com? That does not sound like a real web site to me. You will also notice that he asks you to click on bank-of-america-accounts.biz - a different domain name. That's a dead give-away. But in the world of the Internet, that is verifiable. In fact, it turns out both domains are owned by the same person, one Sharon Besler:
 
Registrant Name:                             SHARON BESLER
Registrant Organization:                     SHARON BESLER
Registrant Address1:                         2448 CRATER LAKE AVE.
Registrant City:                             MEDFORD
Registrant State/Province:                   OR
Registrant Postal Code:                      97504
Registrant Country:                          United States
Registrant Country Code:                     US
Registrant Phone Number:                     +1.5417725178
Registrant Email:                            tooostersf@yahoo.com
 
Now, Sharon may not know a thing about the apparent fraud being run under her domains, although that's probably unlikely. But just for giggles, what happens when you follow the link? You get a cleverly crafted Bank of America page tempting you to login. If you do, your account and password will probably either be stolen immediately or sold to the highest criminal bidder on the black market.
 
BofA.jpg
 
So here they are. The site on the left is the real Bank of America. The site on the right is not. One thing about Bank of America is that they have a randomizer on the home page. Sometimes you enter your PIN, sometimes not. Sometimes you select your state, sometimes not. So the hacker spoof will never be accurate - they have to get all that information on the first page because Bank of America has a graphic-based authentication on the second page that cannot be easily duplicated.

UFO's Over Boston
OK, I saw a UFO this afternoon, where UFO is defined as, 'unidentified flying object' as opposed to 'spooky flying saucer filled with medically curious aliens from Zarquon-9'. In all probability, this was a weather balloon, but who knows. I'll build a little suspense before I get to the bottom of this.
 
So here's the setup. I am in my front-yard. I see a UFO. I watch it for awhile. Eventually, a plane flies by and I take a picture of the of the two of them in the same frame.
 
PlaneandSpec.jpg
 
Do you see what I'm talking about? I bet the pilot of this plane must have gotten a pretty good look at this thing. Now, I'm being a bit smug, because I'd been watching it for some five minutes at this point. My observation was that it was rising and moving with the wind, or at least, in a pattern that looked wind-blown. I have no idea where the wind was blowing up there.
 
UFOLuft.jpg
OK, so here's a closer look at this thing. First, some details. I shot this at 200mm on my camera. That's roughly 4x magnification from normal. Due to the lens multiple (each lens is 1.6 times the rated focal length because the imaging chip is smaller than a 35mm frame) it's actually a bit more than that, but it doesn't matter much. What does matter is that I basically tried not to mess with the photo too badly. I made a few adjustments for contrast and sharpening and a massive crop.
 
So having said all that, it looks like an instrumented balloon to me. It does not look like a weather balloon. Thankfully, it didn't look like one of the recent sightings out west. If anyone knows what's up with this thing, let me know.

ChaCha Signs Indiana University (funny, but obscure)
Well, I noticed on slashdot that ChaCha, the human-powered search company, has signed a deal with Indiana University to 'replace' Google as the default search technology for the campus. I've reported on ChaCha before, but once again, Slashdot's comments have proven interesting. There's the usual quibbles about conflict of interest (the IU president, Michael McRobbie, previously sat on ChaCha's board) and the joy of messing with ChaCha guides late at night. But the comment that had me on the floor was this one:

Googlebotter: It's people. IU Search is made out of people. They're making their index out of people. Next thing they'll be breeding them like cattle for links. You've gotta tell them. You've gotta tell them!

Slashdotter: I promise, bottie, I promise. I'll tell the geeks.

Googlebotter: You tell everybody. Listen to me, Slashdotter. You've gotta tell them! IU search is people! We've gotta stop them somehow!

ROTFLMAO
