Prediction for CME (2023-03-12T19:24:00-CME-001)

CME Observed Time: 2023-03-12T19:24Z
CME Note: CME going South in SOHO LASCO and SSW in STEREO A COR2. Its source is a gradual eruption of complex, mostly longitudinally oriented filament centered approximately around ~S25E20 (filament seems to extend from at least S5 to S50) and is seen starting to erupt in AIA 304 and 193 around 2023-03-12T18:30Z. Possible arrival is marked by an increase in B_total from 8 nT to 22.5 nT, reaching a maximum of 26 nT at 2023-03-15T05:02Z. Accompanied by an increase in speed from approximately 420 km/s to 550 km/s, an increase in density, and increase in temperature. This arrival could alternatively be attributed to a predicted glancing blow from 2023-03-13T10:53Z CME (possibly more less likely due to the earlier observed arrival at STEREO A). LASSOS discussion summary about this signature: this is likely a strong glancing blow from a CME, with a sheath and a shock-like structure.
CME Shock Arrival Time: 2023-03-15T03:48Z

CCMC 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.
