Broken cloud today but a very strong wind prevented me from deploying the "big guns".

There is a new active area right on the meridian in the northern hemisphere. Unable to use the FLT110 due to wind vibration, I was restricted to 60mm aperture - the loss of resolution is obvious but I have just about managed to capture the "rice grain" granulation:

1409 UT. Lunt 60mm, Lunt solar wedge, 4x Imagemate, DMK21

1427 UT. Lunt 60mm, Lunt solar wedge, 4x Imagemate, DMK21

Meanwhile, the main spot in AR 11101 persists, but the pores in the trailing plage seem to have decayed:

Here's a 3 frame mosaic showing the active areas in Ha:

Prominences were small but interesting; N limb:

SW limb:

1455 UT. Solarscope 60, 2.5x Powermate, DMK21

ESE limb:

1456 UT. Solarscope 60, 2.5x Powermate, DMK21

Transparency good between broken clouds rapidly forming, decaying and drifting in the strong wind. Seeing moderate with significant boiling. Wind N force 5-6 with occasional gusts to force 7. Temperature 15C.
