The large sunspot — designated AR2665 — that rotated out of view about two weeks ago has returned, seen in this footage captured by NASA’s Solar Dynamics Observatory on Aug. 1-2, 2017. Sunspots can last for months, so it’s not unusual to see the same sunspot several times. Numerous magnetic loops and arches stretch above the sunspot, seen here in wavelengths of extreme ultraviolet light. This type of light is typically invisible to our eyes, but is colorized here in gold. Though much reduced in
