Prediction for CME (2019-05-07T04:42:00-CME-001)

CME Observed Time: 2019-05-07T04:42Z
CME 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).

CCMC Rules of the Road: CCMC requests that users notify the CCMC, CME model/technique developers and submitting forecasters/researchers before performing event and validation studies with data from the CME Arrival Time Scoreboard. It is recommended that such studies be performed with the knowledge and collaboration of developers and submitting forecasters/researchers.
