Event 1998/02/20

    CME (C2/C3):
                First appearance in C2:                  08:55 UT
                Average velocity in C2/C3:           519 km/s
                Average acceleration in C2/C3:     15.6 m/s/s
                Position Angle in C2:                     93 degree
                Angular width in C2:                     74 degree
     CME (C1):
                First appearance in C1:                   N/A
                 Magnitude:                                        N/A
                 Onset Time:                                      N/A
                 Peak Time:                                        N/A
                 End Time:                                         N/A
                 CME final speed:                              519 km/s
                 Flare rise time:                                   N/A
                 CME acceleration in rise phase:        N/A
        Source Region:
                 Behind but close to limb based on EIT and SXT
                  C1: no apparent LE seen, probably due to no shparp edge
                  SXT: 08:40 UT, eruption from behind the limb at PA ~135 deg
                  EIT: 08:20 UT, Pos. 135 above the limb, regional expanding
                  GOES: no flare associated. The flare at 10:00 UT is from a different location
