Ok, it took me 2+ days to get back from the eclipse, catch up on my sleep (and food), unpack the car, and start to look at the data. This has been my first chance to get online and upload a few pictures.I had an extra camera, a simple little "point-and-shoot" snapshot camera, which I wasn't otherwise going to be able to use during the eclipse, so I gave it to one of the kids with a large party from the Merced, CA, area who camped across from me. I wasn't able to collect names, but one of them took this nice shot during totality:
Compare with this thumbnail photo of the inner corona from the front page at Wikipedia 2 days later (over at the "recent news" on the righthand side):
This eclipse was noticeably brighter than the one 38 years ago, meaning the corona was much brighter and more spectacular. I also didn't notice any shadow bands just before (or after) totality this time; they were perhaps the most prominent feature of the previous eclipse, though the sight of the corona at totality is always incredible. Photos really can't convey or give a good impression of what it's like being there. This is probably the result of the corona having a range of brightness of at least 500x, from the faintest outermost whisps to the regions near the sun/moon's limb. The eye is able to accomodate this high dynamic range, which is roughly 9 stops in photographer's lingo, though it's very difficult to compress into the range available with cameras and the means one might use to display the images made with them. Ansel Adams would have said the scene's brilliance is too great for the medium.
The GPS coordinates were measured as: 107° 55' 18.6" (W), +43° 11' 45.3";
5075 feet. (car @farthest right w/trunk up)
This web app output from NASA shows the relevant stats for this spot:
The nearest point on the centerline SSW of us (i.e., along a perpendicular from it) was 4½ miles away, but this made only a 1.4 second (1%) difference in the length of totality. The point on the centerline which had an exactly identical time of maximum eclipse was a little bit further along the track (more S-SSW from our location) and closer to 4 5/8 or 4 2/3 miles away.
According to one source, some 600,000 people from Colorado were expected to go up to Wyoming for the eclipse, which only has about that number of people all told (CO has ~5 million) -- and most of them I actually avoided since they were heading back down I-25 from Casper to the large cities of the Front Range. Being around quite a few gas stations and at least one restaurant on the trip, I saw mostly Colorado license plates.
Also: thanks to the party from Salt Lake City camping next to me, who had extra reserves of water to share with me, since I only had two quarts. They told me about the almost 2-meter class telescope the astronomy club there was putting the finishing touches on.
By the time I made it to Rawlins and I-80 around 10PM the traffic had thinned sufficiently -- twice as many lanes certainly helped also -- to be back to normal speeds. But in the long stretch of two-lane south to I-70 at Rifle, CO, I started to get blurry-eyed in the early AM hours and had to pull over for a several hour nap, not making it back to Montrose until 8 AM. I quickly turned on the morning TV "news" to catch up on what scientists were reporting about the eclipse, only to be treated to typical celebrity crappage about what Sarah Jessica Parker had seen in New York city, which only had a √2-1 eclipse. Then, as if that wasn't bad enough, they had to have a zany, madcap plot line where one of the show's hosts couldn't find her way out of the studio and down the back stairs to get outside. OMG, she's going to be late for the eclipse! This is criminal misuse of the public airwaves.

An Eclipse Expedition of the Past
A Funny Thing Happened On the Way to the Eclipse
For anyone who's been checking, I haven't posted anything new here since shortly after the eclipse -- as a result of being given a case of HOA Syndrome: three weeks before the eclipse, the Montrose Mafia stole my car out of my driveway, forcing me at first to think I was going to have to ride my bicycle ~400 miles to the centerline, and then later to get my collector car out of mothballs at the last minute in order to make it to the eclipse [HOA = Home Owners Association].
I get around entirely by bicycle, for 4 years now, so them putting my now stolen and held hostage car 10 miles away made it impossible to try and retrieve. For one thing it needed a new battery, which weighs some 25-30 pounds. For another, I'd been siphoning all the old gas out of it over the Summer (and burning it in the BBQ), in preparation for taking it to the eclipse, and there are no gas stations within about 8 miles of where they had it, so I also would have had to bicycle down there with at least 1-2 gallons of gasoline. For a third, it hadn't been run for 4 years, and while I would have expected it to start up fairly easily, in the event that it didn't there was no auto service nearby, just like there wasn't any gas.
Not only were they expecting me to also give them nearly a kilobuck for the 'privilege' of being harassed, bullied, and robbed by the property management company's Mr. Big and his lawyers, NOW they've upped the ante and are suing me for $4.3K -- on a car that was likely worth less than a half that! It's sixteen years old, has been hit by a deer, and needed some other fixes, like for the cracked windshield it's had for 7 years.
Anyone up for starting a legal defense fund? Running
legal plunder total so far: $92 (to file an ~85 word statement
w/the court, for the equivalent of ~3 weeks worth of groceries- gah!)
Anyone know any lawyers? Anybody have a Varon-T disruptor I can borrow? My Higgs field enhanced model (v.2) is still under construction.
Or maybe one of you 'special-ops' types can get the GPS coordinates 38°28½'N, 107°52½W on North Korea's ICBM targeting list. That'd fix `em real good.
HOA Syndrome is a form of anxiety disorder, and the list of ~25 indicators for it, well, I've got at least a half dozen of them -- plus a few that aren't listed, like my cat's behavior; pets act as a mirror on their owner's mental state.
On top of that, MicroSoft dumped an "update" on me two or three weeks after the eclipse, and now my programming environment no longer works. I was right in the middle of writing some code to do some calculations and make a graph, but attempts to figure out what went wrong and how to fix it have been to no avail... Well, it must have been some obscure compiler glitch, because switching a few lines of code around, which shouldn't have made any difference at all, made the bug go away. So here's the graph:
Continuing... And then, barely a week after getting back from the eclipse, there was the 8th-9th magnitude Asteroid 3122 Florence flying by close to the earth; it won't be back for several hundred years. I got 5 hours of great observations (some 700+ frames), and have been assembling a time-lapse movie when I get a chance.
But I did get some excellent results for the eclipse, like a picture during totality showing Regulus in the frame (a section of which is shown at right), which I haven't seen anywhere else. My focal length was chosen with doing this very thing in mind. I also haven't heard of anyone noticing it visually during the eclipse. Everyone I talked with beforehand was looking to see planets during totality.
This view is in an Alt-Az orientation; Regulus was actually ~½ arc-minute N of the Sun in equatorial/celestial coordinates then, meaning the ecliptic goes below it. It was 1.3° from the center of the Sun, or almost 5 (4.96) solar radii (Rο). The outermost coronal streamers seen here hit the frame edge at a little less than 4½ (4.45) Rο. At shorter exposure levels all the streamers go straight in to 1 Rο, so they're almost more in the way of jets emanating from the surface (photosphere or chromosphere).
There are two 7th magnitude stars in the field near Regulus. In this orientation, one (HD 87647 / SAO 98949, 7.35 mag) is ~1° almost directly above Regulus, while the other (HD 87271 / SAO 98931, 7.10 mag) is almost the same amount directly to its right. The latter star is lost in the bright coronal streamer near the right edge of this crop, but the other is easily visible (if on the faint side) in the original frame above what's shown here.
[An approximation exists for the conversion between Naked Eye Limiting Magnitude (NELM) and sky brightness in Magnitudes Per Square Arc-Second (MPSAS), courtesy of K. Fisher. Unfortunately his chart only goes as bright as MPSAS=16, where the NELM=2.2, which is about a magnitude fainter than Regulus (1½). While I had aspirations of measuring the sky brightness directly during totality (with a meter), I wasn't able to do so (not enough hands), though post-eclipse estimations and test/calibration exposures during twilight ~25 minutes before sunrise put it closer to 13½-14. Extrapolating Fisher's relationship to this level puts NELM at -0.2 to +0.3, which is too bright by at least a magnitude to have allowed Regulus to have been seen, especially so close to the bright corona, perhaps explaining the observations (or lack thereof). Mars, at mag 1.9, 8¼° above and to the right of the eclipse, also should have been beyond apprehension, but more distant Venus (34°), at -3¾ below Gemini should have been easily visible. After doing the above I found this nifty and handy NELM / MPSAS Conversion Calculator, which gives the same results.]
I also got a great sequence of the Diamond Ring effect, and, more importantly, a good timing of its duration accurate to ±½ second, something else I haven't seen anywhere else before. This in turn gives a measure of the physical depth of the canyon on the limb of the moon responsible for it. Before releasing the figure I wanted to make a survey of peoples' subjective determination of the effect's length, to compare "eclipse time" with the hard and fast measure from an unaffected clock.
Still confused about the car? Yes, you should be. What happened was I parked it as I always did in my driveway. Then I took to my bicycle. No problemo. There the car sat for 1, 2, 3, 4, .... 46, 47, 48, 49 months. I cleared the snow off it when needed, pumped up the tires when they started to look a little low, etc. (The relevant legal concept here is called "Acquiescence" or "course of conduct".)
Evidently 50 months was one too many, as Mr. Big then declared my car "abandoned" -- by having a hoakey "notice" (printed on bright red paper, to look important or official, or something) taped onto the windshield. The basis for this was that the registration tags on the car were expired (not one, two, or three years, but four), something which could only have been determined by someone trespassing onto my side of the invisible three-foot property line around my house, as I always back a car in when parking, so the license plate was up against the garage door.
There was supposedly a way to contest the notice to the Property Theft Mgmt company, which I did by explaining I was in fact going to get the car registered within about another two months in order to drive it to the eclipse (which was also why I held on to the car rather than sell it). What possible difference could 51 months vs. 49 months and a 1 square inch little sticker make to anyone with half a brain left? Not much, so obviously this made little impression. Then the threatening and harassing letters from the lawyers started, followed by them sending their thugs to tow the car away. One threatened to "call the sheriff" when I protested, which I probably should have encouraged him more to do, while the other one was just muscle who didn't say anything.
As Mr. Big had been over here practically ranting at me about how he was going to foreclose on (read: steal) my home -- which made no sense since I have no mortgage (the place is fully paid for) -- this ought to eventually make an interesting test case for Colorado's "Make My Day!" law.
A copy of a letter I sent to my HOA neighbors has another choice Ward Lucas quote in it. He's the only person ever to have cooked up a batch of chili with a solar oven during the two hour stretch of a total eclipse from first to fourth contact!
The previous HOA president replied to my letter, starting out, in typical cult-like, Nazi-esque fashion, by lecturing me on "how we must all follow the rules, like it or not". Like H.L. Mencken said, in his typically acerbic and facetious manner, "the goosestep is the perfect symbol of 'civilization'."
What's actually funny about all this is that as a homeowner I'm ostensibly part of the homeowner's association, which means I'm suing myself, without having done anything! Either way I win. It's kind of like some sort of Jedi trick, only backwards.
The Tyson Effect?
