Morning disappointing with much mid level cloud partially clearing later, then sea fog spreading in. Afternoon clearer but seeing very unsteady.

Solar disc features similar to previous few days

1008 UT. Coronado PST CaK, prime focus, DMK41

Active area 11076 appears to be starting to decline. The large trailing spot has split into two, the penumbra is starting to fragment and the trailing spots are disappearing.

1019 UT. Solarscope 60, 2.5x Powermate, DMK21

1340 UT. WO FLT 110, Lunt solar wedge, 2.5x Powermate, DMK21

The minor activity north west of AR 11073 now consists of a single small spot with just a suspicion of a couple of pores trailing it

1021 UT. Solarscope 60, 2.5x Powermate, DMK21

1341 UT. WO FLT 110, Lunt solar wedge, 2.5x Powermate, DMK21

The train of filaments in the north continues to be a prominent feature in Ha

1320 UT. Solarscope 60, 2.5x Powermate, DMK41

There is a medium sized quiescent prominence on the NNE limb

1038 UT. Solarscope 60, 2.5x Powermate, DMK21

a group of small faint prominences on the east limb

1313 UT. Solarscope 60, 2.5x Powermate, DMK21

and low bright eruptive activity on the west limb

1308 UT. Solarscope 60, 2.5x Powermate, DMK21

but the best prominence on show is a large complex but not very bright one on the SW limb, which is evolving quite fast

Morning session: Transparency poor & variable (drifting sea fog), seeing moderate. Temp 20C, wind NE force 2-3. Afternoon session: Transparency good with occasional interruption from thin mid level cloud. Seeing bad with severe boiling. Temp 19C, wind variable force 1-2.

(I'm still trying to find the time to do some processing from the 4th!)
