Transparent airstream though with some interference from cloud. Seeing was steadier than usual at times but very variable.
Active area 11455 has grown quite large but does not have large spots.
0949 UT. WO FLT 110, 4x Powermate, Lunt solar wedge, ND 3.0 & Wratten 29 filters, DMK21
1130 UT. WO FLT 110, 3x teleconverter, Solarscope SF-100 Ha filter set, DMK21
1005 UT. WO FLT 110, 2.5x Powermate, Lunt B1200 CaK diagonal, DMK21
Several other minor spot groups were recorded. Here's an overview of the solar disc showing that the filaments which have dominated the disc recently are persisting:
0935 UT. Solarscope 60, 0.5x focal reducer, DMK41
There were also several prominences on show, here's the most attractive, on the north west limb:
1110 UT. WO FLT 110, 2x Powermate, Solarscope SF-100 Ha filter set, DMK21
And there is Something Interesting just appearing at the eastern limb!
