Original Caption Released with Image:

A large group of sunspots that rotated across the Sun over six days (Aug. 21-26, 2015) started out as a single cluster, but gradually separated into distinct groups. This region produced several M-class (medium-sized) flares. These were the only significant spots on the Sun during this period. The still image shows the separated group as it appeared on Aug. 26., 2015.
