What a show! Yesterday Aug30 around 12/13UT an M3.8 flare occured in new delta AR3806, accompanied by the fast rise and fall of a big eruptive prominence from a region just behind East limb, probably connected to 3806. Also new gamma AR3807 flared in sympathy. The event began at 1215UT at C3 background. In just 5 minutes the M3.8 peak was reached. I was observing in visual and gasped when I saw not only a bright flare in 3806, but that flaring prominence. During the 20-min descent of the flare curve, the prominence lost luminosity but swelled and I got the first three gif (timelapses) (the no.1 is just a crop of no.3). The fourth timelapse covers about the subsequent hour, featuring an afterflare with a C6 plateau peak (again involving the three regions mentioned above); indeed this movie shows a secondary flaring eruption (rising, moving and falling). This phase is also the end of the main peak, and the movie shows the eruptive plasma falling back to the surface, guided inside the prominence's tube of magnetic flux.
