Brian Head 5/20: eclipses are bullshit

Someone says, "On a scale of 1-10, annular eclipses are a 9, partials a 5, and total eclipses, like, a million". Well, normalize those numbers and you get a 10 for total eclipses, 0.000005 for partials, and 0.000009 for annulars. Sounds about right, at least for the last two.

I wanted to see Brian Head, I wanted to head down south on a whim, I wanted to not miss something that happens rarely enough. So I went to see the eclipse. The day started well enough: during brunch at Sundance, I talk the waitress into giving me their last -- she said -- discount card for all Sundance restaurants. Many visitors coming over the summer and this'll save me a ton. I also got an oil change yesterday and had my tires pumped up to 125% of recommended. As I get on I-15, I am getting crazy good mileage. The drive is pleasant enough. It's been a while since I came this way. As I pull up to the ticket booth, there's a decent line. In front of me are people from LA, Las Vegas, Ogden. First snafu: they're rationing eclipse glasses -- "No eye protection for you!" One pair per group, they say. Well, I should be set, then: party of one. The LA people are eclipse dorks. They are spouting eclipse trivia, and tales from their previous expeditions to Africa, Turkey, France, Caribbean..."and then a cloud appeared out of nowhere!" I pretend to be interested, in case I can't get a pair of glasses -- these people have some extras. They keep the glasses from each trip, apparently.

We get on the lift, get off the lift. Expansive view. I find a somewhat isolated spot and share it with a couple. They're from Austin but recently moved to Cedar City because they love Utah. We exchange tips on trails, dirt roads, favorite red rock vistas. Very mellow, interesting people. Then it starts. That much I know by looking at the time. Nothing of note is really happening. Though, if you put the glasses on and blind yourself to everything else, you see a nondescript light disk with a dark disk in front of it. Fascinating. We keep chatting. It's a nice location to spend an early evening. The tension builds as the clock nears 7:30. I take some pictures of the surrounding area. Just getting reacquainted with the big camera after lazily using iphone for everything. Though, I resolve to put it down in time and just enjoy the eclipse. Which I do. Sort of. The small dark disk moves completely in front of the big light disk. People cheer. One guy has his back turned to the sun and is talking on speakerphone to his wife, "We are seeing the eclipse! It's happening right now!" I don't really see him looking at the eclipse, though he'll probably go home and tell what a grand event it all was. One kid proposes to his girlfriend with a bouquet. It's probably from Smith's. Earlier, the guy I am talking to joked about it being for him and the kid said, "No, I brought it for your wife." He said this very innocently, thinking it a compliment and a witty retort. His girlfriend will spend the rest of the eclipse on the phone to her parents.

There is an unusual light. It's noticeable but not particularly interesting. It had also happened in the 0.000004 less interesting 1994 partial eclipse. In a last attempt to get something out of this eclipse, I glance quickly at the sun with just sunglasses. To hear people talk about it, I should have turned to salt there and then (or, six hours later). I don't. Because the sun is very low, and the moon is in front of it. But you won't hear anyone say that in our infantilizing culture. Someone went as far as to write that you shouldn't look even right at sunset because...? Why? Is everyone who's ever looked at a sunset now blind?

Soon, it is over. We pack up and say our goodbyes. The line to get down the lift is very long and not moving. They are loading every 5th chair, with frequent, long pauses. I notice the eclipse dorks. They have all sorts of equipment out. I look at the pictures they've taken. Very similar to but not as good as the ones you get by typing "annular eclipse" into google. This could be from their previous trip, for all I know. But they are high-fiving because they think they got some obscure phenomenon, having to do with when the two disks touch. Looks to me like camera-shake.

The line is still not moving. Me and some other people decide to walk down. Turns out we will beat not only everyone in the line but also some of the people who were already on the lift. That's how slow it's moving. I wonder how cold it gets at 11,000 feet after 10 pm.

On the way back, I-15 is more crowded than I've seen it on holiday weekends. Some crazy drivers, probably ecstatic from what they've just experienced. South of Nephi, the traffic comes to a standstill. It's taillights to the horizon. Luckily, there's an emergency turn 20 yards ahead and an exit 1 mile back. When I rejoin the highway some miles ahead it's eerily empty. Must've been a big accident (when I check the traffic around 1am at home, that stretch was still flashing red).

All in all a memorable day but the eclipse didn't have much to do with it.

PS If you want to be impressed by the skies, go up to Snowbasin the night when they have the local amateur astronomers bring their telescopes to the top of Needles gondola. Or, just look up on a moonless night in Southern Utah.

That is an exaggeration but the basic principle is correct. I was quite explicit in this regard leading up to this eclipse. It also reinforces the point that come 2017 people who are lazy and stay home because it's 90% or whatever there instead or driving a few hundred miles to get in the path of totality will continue to think that it's not a big deal.

Interesting to hear about the overcrowding at Brian Head. I'll bet Bryce, which has ongoing astronomy programs and scheduled their annual 4-day astronomy festival last weekend, was a real zoo.

I'll let admin tell his story from our get together near Lake Powell. But his well known crowd phobia is probably appropriate in choosing a viewing location. Page, AZ was solidly booked for hotels and there was some restaurant crowding, but here were enough decent viewing spots in the area to avoid crowd or traffic issues.

With 12% of the sun's surface area still exposed it is quite striking how little effect there is on light. Sharper shadow lines, projected crescents, etc., but someone who was doing something else and didn't know there was an eclipse might easily not even know it was happening. You have to cut it down to the last 1-2% for it to be obvious. Admin just missed totality in March 1970 by I'd guess 50-100 miles and does remember it getting much darker. What was noticeable with 88% obscuration was the drop in temperature, quite welcome as warm as it was in Page. This was also noticeable in L.A. 10 years ago for a late in the day 70% partial eclipse.
 
I think Evern might be reacting more to the eclipse watching scene than the eclipse itself, but mostly I agree with his major points. I'm all for cool astronomical events, but there are some I won't travel for - eclipses fall into that category. As an excuse for a party with excessive drinking and eating, sure, but I better be able to see it from my front porch.

Now driving 2hrs into the west desert to view the Perseid or Leonid meteor showers with a bottle of wine and some snacks is something I've done a number of times.

Bingo! Marc... you "get" me :shock:
My impression of eclipses -- granted, formed without seeing a total one -- is that they're more about the scene than the intrinsic qualities of the event. Sort of like all those crowds that congregate in front of the Mona Lisa: if they asked themselves honestly whether they were having a transcendental experience, the answer would have to be no. But then, they are at a "certifiably important" experience, with a bunch of other people who are reacting the same way, so that colors the memories formed. These are the same people whose reaction upon seeing an icon like the Eiffel Tower is to turn their back and have their picture taken -- "I was there" becomes more important than the actual event.
And while there is an intrinsically fascinating object to see in many of these iconic events/places, some of them (like the Mona Lisa) I don't "get". Eclipses (so far) are in the same category.
That's what makes them :bs:
Now, totality may be in a different category altogether but annular was supposed to be much better than partial, too, and I didn't find that to be the case.

It was no more than 150 people, I'd say. The guy on his phone (and some shrill college kids nearby) did make it feel a bit crowded but overall, I'd rather have a crowd that size than none at all, for something like this.

And it turns out, the traffic jam on I-15 was due to UDOT treating this like any other Sunday night and restricting lanes for construction.

I wonder why that is the case. Are we getting that much of perceived sunlight from the sky rather than directly from the sun? Then again, when I briefly looked directly at the sun, the disk itself seemed very bright, despite being 94-96% obstructed.

Staley, I made a good effort to stir things up but... Tony took a very technical approach and Marc_C actually agreed with me #-o . What else is there to do?

I agree, the shortcomings of this thread are no fault of your own.
 
Venus transit on June 5th. Chance of a lifetime \:D/ I smell roadtrip!

No roadtrip necessary for that one, unless you're a fanatic and want to see all 4 contacts. Visibility range for transits are like lunar eclipses, crudely half of the earth. Since the Venus transit lasts 6+ hours, more than half the earth will see at least some of it.
espenak-globalvisibility.png

Contact times within the USA are here: http://eclipse.gsfc.nasa.gov/transit/ve ... y12-2.html
First contact is just after 3PM Pacific, 4PM Mountain time. Second contact is about 18 minutes later. 3rd and 4th contacts are not visible from the continental US but are visible just before sunset from Hawaii. Xavier, who was with us at Lake Powell for the annular eclipse, will be in Kona for the transit. Liz and I will be content to drive ~10 mins to Griffith Observatory where local amateur astronomers will have their scopes set up. Venus is large enough to be seen with appropriate solar protective eyewear without magnification, though it will be better with binoculars or a telescope. The more frequent Mercury transits (I've seen parts of 2 of them at Griffith in 1999 and 2006) are not visible without magnification.

I was on a Mediterranean cruise with Andrew and saw all 4 contacts of the last Venus transit on June 8, 2004. They come in 8 year pairs separated by over a century. So if you miss this one the next will be in 2117.

Contacts? All 4???
 
First contact: Venus and the Sun externally tangent but Venus not yet in front of the Sun
Second contact: Venus covering part of the Sun but outer edges internally tangent
About 6 hours later third contact is the internal contact and fourth the external when Venus is no longer in front of the Sun.
 
These were my best attempts given my hastily engineered camera filter. I like solar events I can see from my backyard O:)

Although it was windy and had cloud bands at times (as seen in the pics).

View from Ottawa was different as Venus was at the top of the sun. We went at the Canadian Science and Tech museum to watch the beginning of it. Telescopes everywhere. Clouds started moving in once we were back at home at around 8pm, so we got a 2-hours clear view. I needed my eye glasses to it (another sign of aging).

As a geographer, I thought it was cool.
