Continuing our conundrum of trying to understand Meteoblue's data, once again they had the seeing as sub 1 arc second while both indexes were average (4 and 2) and the jet stream was high at 31m/s. The actual outcome was worse than the indicated 4/2 indices, more like 2/1. This seems to happen every time with their data, when the arc seconds are less than 1, the seeing is terrible. Go figure!
In the brief time before the clouds came in we captured a full disk and a close up of the amazing complex of ARs 3145, 3140 and 3141.
Full disk Ha image taken with Daystar Solar Scout 60 double stacked with Lunt 40 etalon, ASI178MM camera and 0.5 reducer.
