Prominences and sunspots on the Sun in Ha

Prominences and sunspots on the Sun in Ha

Date/Time: July 31, 2012 2:12PM PDT

Location: My home, Victoria, BC, Canada

The large prominence at the 9 o'clock position on the solar disk started life as a flare and is now transitioning into a large prominence. Sunspot 1532 is just above the centre in this photo, and Sunspot AR1530 is to the right, midway between AR1532 and the edge of the solar disk. Sunspot AR1534 is clearly visible at the 8 o'clock position, and has an impressive solar storm swirling around it on the Sun's surface.

Hutech-modified Canon T2i dSLR a-focal through a 2.5x Powermate, IDAS VLC filter & Lunt LS60THa + LS50FHa solar telescope mounted on an HEQ5 tracking mount.
