Prediction for CME (2021-05-22T09:12:00-CME-001)
CME Observed Time: 2021-05-22T09:12ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/16938/-1
CME Note: Source is eruption from AR 2824 at 06:15Z, with dimming towards the S of the AR. Material moving after 06:45Z to the W from AR. In STA Cor2 it is seen as two CMEs, NW one at 08:23 and SW one at 09:38 (the later might be associated with a C-class flare at 06:45Z). The CMEs are seen as one in SOHO/LASCO C2/C3. CME ARRIVAL: Teresa Nieves-Chinchilla: signatures of flux rope(s) between 05/26 ~ 18 hrs to 05/27 ~ 5:00 hrs, but it may be either two flux-ropes or a single complex structure with internal signatures of interaction. First rotation Bz north for ~3 hrs starting after ~18 hr and then ~19 hrs another structure with SN rotation in Bz. The second one displays low solar wind temperature more consistent with the magnetic cloud/flux rope expected signatures. Note that bulk velocity for the whole period is increasing - also a signature of compression, so it seems that there is interaction.

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.
