The sky this morning was a bit cloudy and I patiently waited for the clouds to persist as I want to monitor the long dark filament that I saw yesterday at the NE limb. Although I can see it in my monitor screen, I wasn't able to image the Sun till past lunchtime! I have to bring all my solar setup down to the laundry area for me to image the Sun at that time!
As I train the PST-Ha at the Sun, I was surprised to see a large bright eruptive prominence in the western limb which I didn't see in the morning. The changes in that prominence was very fast as the prominence changed structure in less than 13 minutes!
