This multi-flame picture shows you the progress of the total solar eclipse on Aug 21, 2017 observed at Salem, Oregon. The sun started to be eclipsed from its western rim at 09:05 past in local time, and the sun was totally eclipsed for a bit shorter than two minutes from 10:17 until 10:19. I observed three prominences with comparatively larger scale in west rim. The solar activity has been in time of minimum, the corona is spreading in east and west directions. And in that day, two small scaled sunspot groups of #2671 (in center) and #2672 (around east rim) in NOAA's ID were detected on the solar surface.
