Eclipse Megamovie 2017: How did we do?

The Eclipse Megamovie program, as set up for the Great American Eclipse of 21 August 2017, will have completed its first phase, data acquisition, on that day or shortly thereafter. Our objective was to create (with Google's help) a vast public archive of amateur and other photography, down to the smartphone level, of the corona itself and of Baily's Beads at the 2nd and 3rd contacts. The archive and the consumer electronics enabling it open a large new domain of parameter space for eclipse science. At whatever level we have succeeded, the archive is an historical first, and we hope that the it already has been a springboard for citizen-science projects. We will discuss the execution of the program and some of its science plans/results.
