CME Observed Time: 2024-09-10T00:23ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/33297/-1
CME Note: Wide CME associated with a long duration M1.2-class flare from Active Region 3814 (N15E10) seen predominantly to the northeast in SOHO C2 imagery and east-northeast in STEREO A COR2. The eruptive signature is seen as a large-broad scale destabilization seen as a surge-like brightening in SDO AIA 131, opening and brightening field lines in GOES SUVI 284 with additional dimming and an EUV wave to the north, and bright, high post-eruptive arcades seen best in SDO AIA 171/193/304. There is a data gap in real-time in SOHO LASCO C2/C3 at the start of the CME from approx. 2024-09-09T21:48Z to 2024-09-10T01:25Z. CME arrival detected by ACE starting at 2024-09-12T02:53Z. Increase in B_total to about 16nT with subsequent jump in B_total peaking at ~26nT at ~2024-09-12T09:35Z. This arrival is accompanied by an increase in velocity from ~360 km/s to ~420nT, followed by a second jump in velocity to ~550 km/s corresponding to the additional jumps in B_total. There is also an associated increase in temperature.

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.
