Carlos a good time was had by all and it sounds like you were very successful in avoiding that parking lot called I5.

At 96%, it didn't get dark outside, but the light took on an eerie quality that's hard to describe, and the house's outdoor floodlights turned themselves on.

Yes the light becomes very different and as you say hard to describe even at partial solar eclipses.
Anybody here have an explanation to this?

The eclipse was all white light. 93% here. Sunset and sun rise light is filtered through the more atmosphere, side ways vs. vertical, giving the light color. The lack of colored light was eerie for me.

That's a very good explanation.

More accurately, it was all the red, yellow and green light that was filtered out. All that was left was the blue spectrum from scattered light in the atmosphere. I love the effect of the monochrome light on the surroundings. Everything was in sharp focus.

Message 1885673 - Posted: 23 Aug 2017, 21:54:23 UTC

I drove from Woodland Park, CO up to Nebraska using back roads both ways. About 30 miles north of Scottsbluff was the centerline of totality along a dirt road between State Highways 29 and 71. Lots of folks parked along the dirt road but there was no problem finding a spot to pull off to observe.

The pale light preceding totality was really unusual and the drop in temps enough to pull on my vest.

Totality was really abrupt at my location. I kept looking to the west and really never saw it coming, very flat country western Nebraska. The time of totality was about 2.5 minutes and the so called diamond ring effect coming out of totality was really striking.

The trip home was about 3 hours longer than the trip out, well over 2 hours to cover 12 miles was the worst part.

Never having experienced a total eclipse in my first 65 years of life, this was definitely one of my top 10 life experiences.

I had a NASA volunteer give a presentation the night before and he told us exactly the azimuth and what mountain peak to the west to look for the approaching shadow. He was flying a drone and videoing the entire eclipse. The shadow moves fast, first it wasn't there, and then swoosh, it overruns you.

As I understand it, you'd have to be traveling at Mach 1.5 or slightly faster to follow the shadow.

Nothing an SR-71 Blackbird couldn't handle, but then short of something going to orbit, the SR-71 is no slouch, there isn't a missile that could catch the fastest plane on or above the earth.

Theoretically yes. Modern day SAMs like the 40N6 that travel at speeds of Mach 6 can intercept an SR 71 within an operational range of 250 miles upto an altitude of 18 miles. Moreover, the hostile SAM will fire a salvo of missiles(at least 2-3). So the SR 71 will have to jam, drop decoys and out manoeuvre the incoming hostile missiles.Modern day SAM systems can be loaded with libraries of 3D shapes that can be used by the seeker to identify targets and threats.

Still any missile back when it was flying had this problem, a lack of fuel, I'm sure the top speed is still classified, in any case the SR-71 is at least adequate for doing Mach 1.5, and it has the range too, not bad for plane that uses a decent amount of Titanium.

So who wants to join me for the next one? I am looking a either Texas or Niagara Falls. The falls are right in the middle of totality and it will be at about 3:02 pm making for a good west facing shot.

The NASA guy said the shadow moves at the apparent speed of 900 mph on the ground. It was quick, but your eye did detect the movement.

The i40 near here might be a bit crowded in both directions in 2024, sure I know some will fly, but not everyone will.

This is the exact spot where I was. I took some decent pictures, but I haven't had time to do anything with them yet.

Starting from there about 2:00, my phone kept directing me onto roads farther and farther from the interstates, but there were still huge delays. Small towns had their police and fire departments out directing traffic. At one point, it took 40 minutes of crawling just to get to a stop sign. When I finally got to I-55 at Livingston and saw how slow it was moving, I said forget it. The gas station had a 20+ minute wait for the bathroom. To make it worse, that's a big hole in coverage for Verizon, so I couldn't get any further directions. I got out a paper map and decided to head north on a back road to Staunton, but there was traffic there too. I stopped for a pizza, looked at the map again, and decided to go waaaay west and then north to Jacksonville. When I got to I-74 there, I stopped for gas. The phone had service again, so I checked the traffic on 55. It showed the red (congestion) finally ending north of Springfield, so I got on and headed back over. Traffic did start moving at 50+ mph (70 zone), but was still very heavy and had more slow spots. Getting closer to home, I heard there was an accident dropping the road to a single lane, so I got off at a place i thought I was familiar with. However, in pitch dark and a raging thunderstorm, I turned the wrong way. Combining that with a closed section of road, I went several miles out of my way. I finally got home at 12:30. I understand I-57 was even worse, the journey taking twice or more as long as it should.

Over a span of about 27 hours, there was a total of about an hour, maybe a tad more, that my car was not running, the longest single interval being no more than 20 minutes. I filled up with gas when I got to Chester; my gas mileage came to about 18 mpg. I filled up again on my way out of town; my mileage for all the time I sat idling was about 5.8.

Southern Illinois is the spot where the path of the 2024 eclipse will cross the path of this one.

That's why you get your butt planted a day before the eclipse at your preferred location. And take your time packing up and hitting the road for the return home.

Actually I'd bet a retrofitted for the purpose F-111C could've done the job. :-D

Ah yes, the Aardvark. Of course the terrain hugging ability wouldn't be needed at least.

I wonder how I missed the piggy.

Nor the afterburner function ether, and it does have a cargo bay for the extra instruments required. ;-)
