Double Loop Prom - 21-05-2020


Recommended Posts

I held an online solar viewing outreach session from my back garden observatory this afternoon and, despite the hazy cloud's best efforts to scupper it all, there was a beautiful double loop prominence on the upper oncoming limb for all to admire through the wobbly seeing. The session lasted two and a half hours; it was great to see change in this area and little areas of bubbling activity around the limb. Here is an image of the prominence taken during the session. The kit used was a Lunt LS50T Ha with 2.5x Powermate and Chameleon3 camera. One exposure for the limb and one for the surface, 100 frames from 1000 stacked for each image. We named this the Dolphin prominence!
