Details:
On July 18 we had the prominent line-up of sunspot groups on the western limb. Around 12.58-14.06 UTC I captured this little sequence of C-class flare activity. AR4143 to the left, AR4136 to the right. Rather interesting activity, but no mayor flares.
115mm APO, Quark Ha filter, Baader ERF, ASI183MM.
