Considering the low solar activity at present, its good to see some prominences as evidence of increasing magnetic activity on the sun. Indeed, its been nice to see the sun at all! Photograph was taken with a Canon 1000D SLR at prime focus on a 400mm telescope fitted with a Hydrogen-Alpha filter. Exposure was 1/350 sec at f11
