Prediction for CME (2023-07-04T04:36:00-CME-001)
CME Observed Time: 2023-07-04T04:36ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/25808/-1
CME Note: Complex partial halo CME comprised of multiple embedded fronts seen mostly south in SOHO/STEREO A coronagraphs but brightest in STEREO A COR2. The CME appears to contain a wide bulk and a very wide faint shock present in the northeast. Likely associated with an eruption near the vicinity of AR3359 (S22E24) seen best as a spray in SDO 193/171 starting shortly before 03:00Z as well as large-scale brightening in SDO 304 seen near 04:00Z. A broad area of large-scale post-eruptive arcades are seen back towards the northeast after the eruption, particularly in SDO 193. Data gaps due to a STEREO A campaign limits analysis of this event. No clear CME arrivals on July 6-8.
CME was not detected at Earth.

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.
