Old Sunspot Returns
The large sunspot (called AR2665) that rotated out of view about two weeks ago has returned (Aug. 1-2, 2017). Though much reduced in size, it did blast a good-sized coronal mass ejection about a week ago on the far side of the sun. Sunspots can last from days to months, so for it to return again is not an unusual event. Movies are available at https://photojournal.jpl.nasa.gov/catalog/PIA21873
