AR2770 has decayed to 20 millionths with 2 spots.  Yesterday, the day after the light bridge crossed the spot, the penumbra disappeared, and today it decayed even further.  So the question is if it will disappear before it turns to the backside of the Sun.  To make up for this, we see three proms.  One in the NW, one in the NE and SE.  For the rest the Sun is very quiet!
