The Sun 31-5-09 - Spectacular tall prominence in NW!

Set up for imaging at 9.55UT and was amazed to see a tall hook shaped prominence in the NW. It looked like a cloud capped spike to start with then the "cloud" slowly curved over to re-connect with the surface. It had faded rapidly by 11.00UT and was gone by 15.00UT. The new AR in the NE still has only one main spot and about 3-4 pores. Tried the Herschel wedge today for the first time imaging and was very pleased with the results, clear granulation, sunspots and pores.
