    CME (C2/C3):
                First appearance in C2:                  23:27 UT
                Average velocity in C2/C3:           289 km/s
                Average acceleration in C2/C3:     1.3 m/s/s
                Position Angle in C2:                    74 degree
                Angular width in C2:                     65 degree
     CME (C1):
                First appearance in C1:                  21:44 UT
                 Magnitude:                                        N/A
                 Onset Time:                                      N/A
                 Peak Time:                                        N/A
                 End Time:                                         N/A
                 CME final speed:                              289 km/s
                 CME velocity rise time:                   ~ 150 m/s/s
                 CME acceleration in rise phase:      ~ 32.1 m/s/s
        Source Region:
                 Behind but close to the limb based on EIT and SXT
                 Probably, an  intermediate CME
                 CME LE in C1 is very weak and diffuse.
                 EIT: no apparent feature, source region behind the limb
                  GOES: no flare associated
