Today I could see 4 sunspots split over three active areas. Active area 933 had two spots, one small and one bigger that displayed an obvious penumbra. Active area 934 had a single small spot. Also, just coming around the limb of the Sun, only just visible, was a single spot in active area 935 (which appears to be a return of active area 930). Despite being greatly foreshortened it was obvious that it too had a visible penumbra.
