Some activity of May 23 & 24

Post by krakatoa1883 » Thu May 24, 2018 4:01 pm

Finally there is something interesting to see :) three active regions each one with sunspots is a rare opportunity during a solar minimum. AR12711 shows about 18 spots, some very tiny but the main one has a well defined penumbra. The AR that emerged yesterday from the E limb is flaring with B- and C events but in H-Alpha I couldn't see any major prominence from it.

Rgds!

Nice set of images, Raf. It will be interesting to see what the new AR brings in the coming days.

Thanks to all. I observed 12712 this morning and this afternoon, it seems still growing with small new spots added but I couldn't detect any major activity. AR12711 seems quiet now.
