The Active region filament, A, appeared to have blown away as a result of a flare at B. During the declining phase of the flare, this filament seperated out into four distinct segments, which were moving out from the active region. The filament reformed at 0741 UT. Note the umbral flare at C which decayed completely by 0728 UT. Bright matter emanating from the umbral flare-sites is clearly seen in 0708 UT frame.
