Thanks for your comment Gus. Considering the conditions, I too, was surprised at the detail. These images are 2 of 25 that I managed to capture at 1 minute intervals. (Avi's of 500 frames in each case) My resulting "movie" shows little structural change over this time. From measurement of the image, the prominence is about 85,000 km high. A faster moving "magnetic loop" prominence would be a better movie challenge. Regards Arthur
Thank you Oernulfs and Phil for your recent comments. It has been so cloudy in Melbourne it is becoming a problem to find the Sun, let alone do some imaging. Regards, Arthur
