Note: This is an extremely faint CME and a possible partial halo seen going to the South East in C3. There could be several potential associated eruptions associated with it, with no definite clarity. Now that C2 images are available, it seems that most probably the CME is associated with a slow lift off of a long N-S oriented filament north from the AR 2740. The CME has an unusually-shaped front (as seen in STA and in difference C3 imagery).
