Motion in the southern region of the NE active region, possible an oscillating filament. Small CME at approximately 00:00 UT, coming from the NE active region.
Very bright loop in active region 8226, possibly a c-class flare, at 17:04 UT. At 14:08 UT there is a jet in the NE active region. Very bright active region developing at the boundary of the north coronal hole. This region borders on the large filament in the SW. See ems19980525_fd_195_b.save (08:00-20:00).
