And then it disappeared, carried by the Sun's rotation out of sight.
But then it, AR4274, reappeared!
AR4274 had returned. It had been tracked via GONG, a global network of telescopes observing the Sun almost continuously since I first heard of it back in 1988. It is not often that sunspots survive a complete solar rotation.
But it did_
I also observed it on Saturday November 8:
This sunspot group may have been responsible for the aurora seen during this time. Unfortunately it was cloudy wet here and I saw nothing but clouds and maybe a faint glow on the northern horizon.
And now solar rotation has carried it from view. Will it return in a few more weeks?
