Event 1997/10/21

                First appearance in C2:                  01:27 UT
                Average velocity in C2/C3:           569.7 km/s
                Average acceleration in C2/C3:  0.9 m/s/s
                Position Angle in C2:                     108 degree
                Angular width in C2:                      91 degree
                First appearance in C1:                  00:53 UT
                 Magnitude:                                        B3.4
                 Onset Time:                                       00:50 UT
                 Peak Time:                                         02:36 UT
                 End Time:                                          02:47UT
                 CME final speed:                               569.7 km/s
                 Flare rise time:                                   N/A min
                 CME acceleration in rise phase:     N/A m/s/s
        Source Region:
                 quiet Sun region, S30E45  (from EIT)
                   Impulsive event, no CME-flare temporal coincidence due to complexity of flare
                   EIT: 00:43 UT, S30E45, start dimming,brightening and expanding
                   EIT: possibly filament eruption
                   GOES: irregular multiple peak flare, may associated with this CME
                  CME/flare: does not fit the time coincidence rule, due to irreguar flare
