Solar prominences on May 24th, 2009
Sketch and Details by Jeff Young
This solar prominence group appeared off the NE limb on May 24th. While much of it was rather dim, it displayed a few bright sections with fast moving action, and it was all I could do to keep up with them. I was sketching continuously for the entire hour depicted here. I would have liked to have done another pair of frames, but was somewhat surprised to find myself exhausted after concentrating for an hour.

Sketched from County Louth, Ireland.
