April 23rd. at 1.53 UT. Noticed this monster prominence on the sun today. This single exposure shot was taken thru a SM II 60 mm scope (Ha) with a Canon 550d camera. Light cloud. I measured the proms height at 91,538 km and base length at 242,300 km. Thanks for viewing. Cheers, JW.
Thanks Richard, Glad you saw it too. I have watched it now for a few hours thru the clouds - it appear fairly stable. Too much cloud now (3 pm afternoon). Cheers, JW.
