Event 1997/09/17

    CME (C2/C3):
                First appearance in C2:                  11:34 UT
                Average velocity in C2/C3:          447 km/s
                Average acceleration in C2/C3:    2.3 m/s/s
                Position Angle in C2:                     259 degree
                Angular width in C2:                     68 degree
     CME (C1):
                First appearance in C1:                  N/A (feature seen at 11:39 may not be LE)
                 Magnitude:                                       contaminated flare
                 Onset Time:                                      N/A
                 Peak Time:                                       N/A
                 End Time:                                        N/A
                 CME final speed:                              447  km/s
                 Flare rise time:                                   N/A
                 CME acceleration in rise phase:        N/A
        Source Region:
                 Close to the limb at PA ~300 based on EIT and SXT
                  C1: structure seen 11:39 UT is not the CME LE,
                  C2: the LE is at 2.68 Rs at 11:34 UT in the C2
                  SXT: erutpion at the limb at PA ~300 deg
                  GOES: M1.7 flare, S11:35, P11:43, E 11:52; it may not be coupled with the CME
                  GOES: CME acceleration time is not known because the flare rise time is contaminated by too overlapping flares
