Prediction for CME (2022-05-03T18:12:00-CME-001)

CME Note: CME is seen to the NE in SOHO LASCO C2/C3 and to the NW in STEREO A COR2 imagery. The source is likely the dimming seen near disk center above AR 3004 in SDO AIA 171 around 2022-05-03T15:00Z. This dimming is also observed to the west in STEREO A EUVI 195 around the same time. UPDATE (2022-05-09T16:27Z): Weak arrival signature indicated by sudden but weak field amplification (only to about 8.5 nT), accompanied by component rotation. Because the L1 solar wind is otherwise quiet, we can see an associated pileup beginning around 2022-05-08T08:03Z. The speed and temperature increase, but they're still pretty low at around 330-340 km/s and 25-35 kK, so these are inconclusive. There are potential signs of separate sheath and flux rope at 2022-05-08T06:24Z and 2022-05-08T12:43Z, respectively.

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.
