Prediction for CME (2023-05-05T08:12:00-CME-001)

CME Observed Time: 2023-05-05T08:12Z
iSWAS Layout URL:
CME Note: Halo CME associated with M2.1 flare from AR13296 (N15E30). From LASSOS team discussion: Arrival on 5/7 is indicated by a sheath crossing and high field strength. No flux rope is observed in this signature. (There could even be 2 iCMEs in this signature, potentially merged). Another candidate CME for this arrival could be 2023-05-04T09:09Z CME.
CME Shock Arrival Time: 2023-05-07T13:20Z
Observed Geomagnetic Storm Parameters due to CME:

Predicted Arrival Time: 2023-05-07T20:30Z (-12.0h, +12.0h)
Confidence that the CME will arrive: 75.0%
Predicted geomagnetic storm max Kp range due to CME: 4.0 - 6.0
Prediction Method: Other (SIDC)
Prediction Method Note:
:Issued: 2023 May 06 1328 UTC
# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
The partial halo coronal mass ejections (CME) was observed in the morning of May 05, first time seen in the SOHO/LASCO C2 field of view at 07:48 UTC. The  partial halo was the result of two CMEs, associated with the C9.5-class flare (from NOAA Active Region 3297 on May 05, peaking at 07:06 UTC) and the M2.1-class flare (from NOAA Active Region 3296 on May 05, peaking at 08:01 UTC). Those two CMEs show an Earth directed component and are expected to arrive on May 07 at the end of the day.
