Returning sunspot group??

Today's Sun with a new large AR coming into view- possibly the return of 2673 and all its friends?  (see entry for 9th Sept – the Sun rotates once in about 28 days so spots that last long enough can reappear after about 14 days of disappearing as they are hidden on the far side of the Sun).  If it is then we should be in for a good show over the next couple of weeks:
