Description

Lots of going on with two large magnetic flux tubes emanating from a group of sunspots that are coming around that has now been identified as group 3774. I was lucky in that I captured most of the activity that let up shortly after I stopped recording data. This time lapse is 102 min with 51 images taken every 2 minutes. The height of the right loop is about 43,000 miles and the width of the left loop is about 85,000 miles. If my calculations are correct, the speed of the changes in the plasma is about 225,000 mph. The seeing was erratic, sometimes quite good to times of bad seeing.
