Event 1997/12/27

    CME (C2/C3):
                First appearance in C2:                  00:33 UT
                Average velocity in C2/C3:            231 km/s
                Average acceleration in C2/C3:      4.1 m/s/s
                Position Angle in C2:                     279 degree (Halo CME)
                Angular width in C2:                      63 degree
     CME (C1):
                First appearance in C1:                  23:07 UT (C1 see different feature from C2)
                 Magnitude:                                        No
                 Onset Time:                                       N/A
                 Peak Time:                                        N/A
                 End Time:                                          N/A
                 CME final speed:                              231 km/s
                 Flare rise time:                                   N/A
                 CME acceleration in rise phase:        N/A
        Source Region:
                 West limb at PA ~ 315 (based on EIT)
                 A case of streamer swelling and blowing out
                C2: slow streamer swelling and eventually blow-out
                C2/C3 H-T data:  for the swelling streamer front
                C1 H-T data:  for the rising loop structure, different from swelling streamer front
