A steady stream of sunspot activity continues to dot the Sun. We had just one day with a daily sunspot number of 0 this week -- January 19 (Tuesday) when sunspot group 1040 moved over the horizon. But the next day, old sunspot group 1039 re-emerged as 1041, and it now graces the Sun's southeast (lower left, relative to our view from Earth) quadrant. In fact, now that we have a view of most of the Sun (87.35 percent -- as of 2359 UTC today -- because of advanced orbiting instruments), it appears that the sunspot group that just left is nearly antipodal to the current visible spot, just exiting the Sun's northwest quadrant. If they stay strong, when the current one leaves, the other should return.
