Sunspots on the increase

NEW SUNSPOTS: In a year when the sun has been utterly blank 80% of the time, the sudden emergence of two large sunspots in a single day is a noteworthy event. Today is such a day. NASA satellites and amateur astronomers are monitoring a pair of growing sunspots, both apparently members of long-overdue Solar Cycle 24. The emergence of these active regions is not enough to end the deepest solar minimum in nearly a hundred years, but they do represent a significant uptick in solar activity.
