Compilation of <a href="https://en.wikipedia.org/wiki/Canon_EOS_400D" class="extiw" title="en:Canon EOS 400D">Canon XTi</a> images (f=18mm) of the southeastern sky, taken before, during, and after the <a href="https://en.wikipedia.org/wiki/Solar_eclipse_of_August_21,_2017" class="extiw" title="en:Solar eclipse of August 21, 2017">Great American Eclipse on 21 August 2017</a>. Photographed from <a href="https://en.wikipedia.org/wiki/Pacific,_Missouri" class="extiw" title="en:Pacific, Missouri">Pacific</a>, <a href="https://en.wikipedia.org/wiki/Missouri" class="extiw" title="en:Missouri">Missouri</a> <a href="https://en.wikipedia.org/wiki/USA" class="extiw" title="en:USA">USA</a>. The timing is based on the totality window presented by <a rel="nofollow" class="external free" href="http://xjubier.free.fr/en/index_en.html">http://xjubier.free.fr/en/index_en.html</a>; latitude/longitude-based inaccuracies are likely. Note the pointed cloud formation at the left edge of the photos above the timberline, and its rapid fade into the background sky.  A smaller cloud nearer the right edge above the timberline, invisible before totality and dark during and soon after, becomes white.
