Flare rise
time:
1200 min
CME acceleration in rise
phase: 2.8 m/s/s
Source Region:
On the limb at PA ~250 deg
Others:
A gradual CME, as seen through the kinetic evolution of cavity top
EIT: 06:59 UT, blob rising and dimming above limb, PA 270
SXT: 08:06 UT, eruption behind of the limb at PA ~250 deg
C2: H-T is re-measured for the top of cavity, which may be
consistent with C1 feature
C2: the original measurement from CDAW catalog is for the tip of
streamer
