Another return?

A small spot or two now logged by SDO at the Sun's eastern limb: latitude and longitude suggest that something of AR12192/12209 is returning from 'farside' transit. "helio" freeware has the limb longitude as ~242, as Dec. 10 UT comes to a close. That's where the huge violet 'following' (f) spot of AR12192 was sited, back in October. Are we to see a third rotation of this active region?
     Heavy cloud and daily thunderstorms making Sun-watching impossible here in the Illawarra region.
