Solar observation (20061217)

A big active region is here (AR930), the sky is very clear, but the wind is very strong too, making any high resolution photography impossible.

Did H-alpha and white light, didn't do white light for long.

Photographs pending.

H-alpha full disc 1502-1503 (HKT), very poor seeing, even small detail at this image scale got messed up, no hope, just a record:-

H-alpha close up 1506 (HKT):-




Prominence 1515 (HKT):-

White Light 1521 (HKT):-
