Ephemeris Extra: My report of the total solar eclipse August 21, 2017

August 24, 2017 1 comment

In planning for this eclipse may main goal was to keep away from crowds and traffic as much as possible.  I originally wanted to stay in Springfield, IL so I could go west or south.  Earlier in the previous week I talked with the University of Missouri Extension service, and offered my services, so I felt kind of was obligated if the weather was half way decent. They were set up at the Howard County Fairgrounds in Fayette, MO.  It turned out that I couldn’t get a room in Springfield, but could 60 miles north in Bloomington.  One of the enticements to placate my granddaughter about the trip, was to visit some Lincoln sites in Springfield, which we did on Sunday the 20th.  On Saturday and Sunday the 19th & 20th the weather forecast for Fayette looked bad with clouds and rain in the afternoon.  So I made plans and checked routes in the direction of Paducah, KY.

I decided, after seeing the traffic heading down to south Illinois on I-55, that if the weather forecast improved for Fayette, MO I’d head there instead. By 11 p.m. the forecast for Fayette improved markedly. It was for partly cloudy skies, and the rain forecast for the afternoon was moved to Tuesday.

We headed out from our Bloomington, IL motel at 3 a.m. The sun came out just before we entered Missouri. The sky was mostly clear with cirrus and some stratus clouds, mostly in the south and west. There was no unusual traffic all the way there.

We were the first to arrive at 8 a.m. About a half hour later we were joined by folks in two cars from Ottumwa, IA. We all stuck pretty much together for the day, away from the building where most of the people, and entertainment was. All in all there were no more than a hundred people there.

As first contact approached it got progressively cloudier. After first contact I went over to the big shed where the entertainment was and some vendors, and gave a short talk on what to expect as totality approached.  We had a $5 hamburger lunch provided by the Howard County Cattlemen’s Association. And bought $10 eclipse T-shirts. For the most part the Sun was visible through the clouds, if hazily. After first contact the skies worsened, eventually losing the Sun at one point, but then the Sun’s image improved, and continually so up to 4th contact. At totality the Sun’s inner corona was visible, but nothing beyond that. So my grand photographic plans were for naught.

However my little action camera recorded the sky for a 45 minutes or so around the time of totality. And with playing it back yesterday, found that it recorded the Moon’s shadow going over very well. From it I’ve created 2 videos, one showing totality in real time, the other a time lapse 2 minute video of 20 minutes centered on totality, in which the shadow of the Moon can be seen passing over us, darkening the translucent clouds from west to east.

I gave my granddaughter, Bernadette (Bea) the job of recording the temperatures as the eclipse progressed.  Here is a chart made from her data:

The high temperature going in was 94.7 degrees, and the lowest was 78.2 degrees just after totality ended.  It was stinking hot going in.  But around totality there was a cool breeze coming from the southwest.  It was refreshing.

I was going to spend more time soaking up the ambiance of the surreal world of totality this time, instead of staring at the Sun and sky. Well, I got it.
