Prediction for CME (2022-03-28T20:23:00-CME-001)
CME Observed Time: 2022-03-28T20:23ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/19574/-1
CME Note: This CME is observed as a halo structure in both SOHO LASCO C2/C3 and STEREO A COR2 white light coronagraph imagery. It is associated with an M1.0 flare from Active Region 12975 (N12W06) and eruption signature visible in SDO AIA 171/193 exhibiting a notable brightening/field line movement starting around 2022-03-28T19:03Z. The shock from the combined front of this CME and preceding 2022-03-28T12:09Z CME is observed around 2022-03-31T01:41Z, followed by the the first flux rope (possibly the flux rope for2022-03-28T12:09Z CME) starting around 2022-03-31T012:00Z. We are likely seeing the start of another flux rope (possibly for 2022-03-28T20:23Z CME) slightly after 2022-04-01T12:00Z when there is a sudden increase in the magnetic field and a drop in density. The end of this second ICME seems to happen on the morning of 2022-04-02 when the field becomes more turbulent, and density increases (analysis by Tarik Salman, LASSOS).

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.
