Event 1997/09/09

                First appearance in C2:                  20:06 UT
                Average velocity in C2/C3:           726 km/s
                Average acceleration in C2/C3:  -7.4 m/s/s
                Position angle in C2:                       284 degre
                Angular width in C2:                      101 degree
                First appearance in C1:                  19:50 UT
                 Magnitude:                                         N/A
                 Onset Time:                                       N/A
                 Peak Time:                                         N/A
                 CME final speed:                               ~800 km/s
                 CME velocity rise time:                 ~30 min
                 CME acceleration in rise phase:  ~444.4 m/s/s
        Source Region:
                  back-side of the Sun over the weat limb (based on EIT observations)
                  a typical impulsive CME, but no flare observed, because of back-side source (Chen, ApJ 2000, MKIII)
                  EIT: start to dimming, expansion and eruption at 19:26 UT above the limb at Pos. 315, see two frames of LE
