Prediction for CME (2024-05-07T05:24:00-CME-001)

CME Note: This CME is very faint but visible to the southeast in SOHO LASCO C2/C3 and STEREO A COR2 imagery following a data gap which ends at 2024-05-07T06:53Z. The source may be related to an eruption/rising loop from Active Region 13664 (S25E05) staring around 2024-05-07T03:12Z as seen in SDO AIA 131. This CME likely combined with several other CMEs from 05-07 to 05-09, with the combined front of the CMEs arriving at L1 at 2024-05-10T16:36Z. The possible arrival is characterized by a sharp increase in magnetic field components with Btotal increasing to 45nT at 16:44Z. A subsequent increase in solar wind speed is observed from 462 km/s at 16:36Z to 703 km/s at 16:48Z. Increases in density and temperature are also observed. A possible flux rope signature begins around 2024-05-10T21:38Z which corresponds to a second, more intense amplification of magnetic field components with Btotal reaching a maximum of 73nT. Within this possible flux rope feature, which extends to 2024-05-11T09:30Z, there are three noticeable decreases in density which may correspond to three CMEs that may have merged into the signature. Because of this, it is possible the signature is associated with the arrival of CME: 2024-05-08T05:36Z, CME: 2024-05-08T12:24Z, and/or CME: 2024-05-08T19:12Z. CME: 2024-05-07T03:12Z and CME: 2024-05-07T05:24Z measured slowly and may have been overtaken by CME: 2024-05-08T05:36Z. Preliminary analysis of this arrival signature was provided by Carlos Perez Alanis from the LASSOS team at NASA GSFC.

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.
