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 (see the image and video here: http://sdo.gsfc.nasa.gov/gallery/potw/item/823). It was showing off numerous magnetic loops and arches above it as it came into view. So we will be keeping an eye on this one for more solar activity. Sunspots can last from days to months, so for it to return again is not an unusual event. Credit: Solar Dynamics Observatory, NASA.
