The spot, previously tagged as AR 1944, was renamed AR1967 as it began its second trip across the Sun’s face in early February. The umbra (the darkest region) of the biggest spot alone was considerably larger than the Earth. Indeed, the group was large enough to show up in nonmagnifying eclipse-viewing glasses!
Will the spot make a third appearance toward the end of the month? We’ll have to wait and see to find out.
The Sun undergoes an 11-year cycle, during which the number of sunspots climbs to a peak before settling down for solar minimum. In theory, at least, solar activity is at its maximum for the current cycle right now — though sunspot numbers have been very low. Not all solar maximums are created equal, however, and the relative quiet of this one is likely a feature of normal, long-term, cycle-to-cycle variations.
