The Solar Chromosphere - 15th June 2017

[David Smith]

Well I finally managed to bludgeon my Ca-K data into submission! Not sure the end result is quite up to usual standards but here we go anyway. 6 Pane full disk took me a while as AS!2 refused to stack one of the panes and when I did get it to stack AutoStitch wasn't having any of it Had a play with MSICE (blast from the past) but it refused to do anything sensible with the data as well. Eventually got AutoStitch to play but I am not sure the output is as detailed as I would expect looking at the source frames.

Proms were, well less prominent today and with cloud heading my way I decided to skip imaging proms in favour of some close ups on the AR's. In my hurry I neglected to shoot a flat for these so you may find they are a little uneven / have some evidence of

The new group looks pretty active with fluctuations in brightness occurring during the relatively short time I was imaging it.

great Ca-K Dave, days like today are sent to test us, when I got up at 7am went into the obsyroom and opened the curtains there wasn't a cloud in the sky, went down to do a cuppa while everything warmed up because sols not in range till 7.45ish and when id got back to the scope it was like 90% cloud and I'm sure thay was laughing at me . charl.
