Details:
I was taking Helium images with the Sol'Ex when solar activity gradually increased to level M and then exploded to X 1.43!
Long-lasting flare since activity remained at level X for 1 hour, from 2:24 p.m. to 3:20 p.m. UT!
The flare occurred on the "old" and hyper active spot AR3664 which is just returning for a second trip to our side of the Sun and which has been renumbered AR3697...
Here are my results (flare is positioned at ~8 o'clock)...
Helium D3 ("Square" image for more contrast),
The flare appears here as three mini shiny spots.
H-Alpha and Ca K (sorry I don't have any better image in CaK due to lack of time to focus in UV because the Sun was setting at home behind a building).
The next few days are definitely going to be interesting!!
