Event 1997/07/08

                First appearance in C2:                  16:09 UT
                Average velocity in C2/C3:           75.3 km/s
                Average acceleration in C2/C3:  9.9 m/s/s
                Position angle in C2:                       279 degre
                Angular width in C2:                      54 degree
                First appearance in C1:                  14:13 UT
                 no association
                 CME final speed:                                       >100.0 km/s
                 CME acceleration time:                          >480 min
                  Average acceleration in C1/C2/C3:    3.5 m/s/s
        Source Region:
                  quiet Sun region close to a small active region at ~S25W80
                  possibly a gradual CME, but more likely an amorphous mass outflow instead of a structure CME
                  C1: cold front expansion, only see CME front in FeX 6376A, but not in FeXIV 5302A
                  C2: very amorphous CME, mixed CME front and streamer, doubt CME ever ejected
                  C2: H-T data is not accurate, not useful for quantification
                  EIT: 12:15 UT, ~S25W80, weak dimming, from a quiet Sun region close to a small active region
                  GOES: no flare
