For today’s session the weather was great, with great seeing.  We have one Active Region left, AR2882, while according to SWPC, AR2883 decayed to a plage this morning.  However, a very nice prominence is visible at the SW limb, which seems to be an extension of the filaments which strech along the edge almost from South. The umbra of the AR2882 seems asymmetric with the penumbra being encroached from the SE and SW.   Today full disk images with close ups of the region and the prom/filaments.
