Mk4 images show the big prominence on the West, especially visible in the realtime scans, but the prominences are on the East side today.

I offset the Mk4 telescope East so the occulting spill would be on the West side, then I looked for a brighter West side in the scan - it was brighter and the East side of the scan was darker. I recentered occulting by reconnecting the cable (I didn't change any guiding telescope adjustment for this test), then the scan got darker in the West and brighter in the East. This is a weird coincidence,I can see prominence structure on the West in scans that match the shape of an EPL on the East side. There is a small prominence on the West side that coincides with the location of the bright structured streamer. The animation shows no structure in the streamer but the realtime scans look very good. **** EVENT COMMENT ****: Wed Jun 27 18:44:13 GMT 2001 That AR on the West limb is very active, possibly flaring, EPL in progress. PA=290.
