Gradual-type CME
In C1, see a blob slowly rising in multiple length, but no general CME LE
The following H-T, V-T plots are for CME core in C2/C3 and blob top in C1
For C1, we use only the 5302 A green line measurement, other wavelengths offset
C2: very structured, multiple helical loops and core
C2: core and streamer tip (CME LE) motions are in phase
EIT observations are not available
