Total Solar Eclipse 2017

Up one level

Total Solar Eclipse - Casper, Wyoming USA - August 21 2017

By Odd Høydalsvik, Bergen, Norway



We observed the eclipse from Casper, not far from Casper Events Center.
Position: 42°51’54” N, 106°19’58” W, Elevation 1583m

Clear sky in the morning. During the first partial phase a few thin clouds were formed. These were present during totality as can be seen from the picture below. Luckily they were so thin they did not obscure the view much. A few details in the corona were lost. But all in all we must be satisfied.

Timing data for the total solar eclipse at the observation site (local time UT-7):
First contact: 10:22:15; Second contact: 11:42:38; Mid eclipse: 11:43:51; Third contact: 11:45:04; Fourth contact: 13:09:26
