Because of Storm Eta, I did not expect to image today.  However, a few gaps showed between clouds enough for some 540nm images today, however it was hard to focus and adjust the exposure.  I waited in vain for some more, but did not get enough time, so finally gave up…..  AR2780 has decayed again to a plage. AR2781 decays also some, and shows less activity.  Today 540nm images of the whole disk as well as a close up of AR2780.
