CME Observed Time: 2022-03-28T12:09Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/19556/-1
CME Note: This CME is visible as a halo in SOHO LASCO C2/C3 and STEREO A COR2 white light imagery. It is associated with an M4.0 flare and eruption from AR 12975 (N12W01). The eruption is characterized by an EUV wave and dimming that is best seen in SDO AIA 193 around 2022-03-28T11:21Z. The eruption is also visible in the northwest quadrant from the viewpoint of STEREO A EUVI 195. The shock from what is probably the combined front of this CME and the 2022-03-28T20:23Z CME was observed around 2022-03-31T01:41Z, it was followed by the sheath and the CME flux rope starting around 2022-03-31T012:00Z (a more coherent magnetic field, rotations, and the sudden drop in proton density at the transition between the sheath to the CME flux rope). We might be seeing the second 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.

CME Shock Arrival Time: 2022-03-31T01:41Z
Observed Geomagnetic Storm Parameters due to CME:
Max Kp: 5.0

## Summary:

Update on CME with ID 2022-03-28T12:09:00-CME-001 (see previous notification 20220329-AL-001), now simulated with CME with ID 2022-03-28T20:23:00-CME-001. Based on preliminary analysis by the Moon to Mars Space Weather Analysis Office and heliospheric modeling carried out at NASA Community Coordinated Modeling Center, it is estimated that the CMEs may affect STEREO A and STEREO B. The leading edge of the CMEs will reach STEREO A at 2022-03-31T07:24Z and STEREO B at 2022-03-31T01:55Z (plus minus 7 hours). 

The simulation also indicates that the CMEs may impact NASA missions near Earth. Simulations indicate that the leading edge of the CMEs will reach NASA missions near Earth at about 2022-03-31T04:12Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 5-7 (minor to strong).
   

Updated CME parameters are:

1: Start time of the event: 2022-03-28T12:09Z.

Estimated speed: ~662 km/s.

Estimated opening half-angle: 50 deg.

Direction (lon./lat.): 3/3 in Heliocentric Earth Equatorial coordinates.

Activity ID: 2022-03-28T20:23:00-CME-001

## Notes: 

The CME with ID 2022-03-28T12:09:00-CME-001 is associated with M4.0 flare with ID 2022-03-28T10:58:00-FLR-001 which peaked at 2022-03-28T11:29Z, SEP at STEREO A with ID 2022-03-28T12:25:00-SEP-001 (see notifications 20220328-AL-001, 20220328-AL-002), SEP at GOES-P with ID 2022-03-28T12:45:00-SEP-001 (see notifications 20220328-AL-003, 20220328-AL-004), SEP at GOES-P with ID 2022-03-28T13:25:00-SEP-001 (see notifications 20220328-AL-005, 20220328-AL-006), and SEP at SOHO with ID 2022-03-28T13:44:00-SEP-001.

The CME with ID 2022-03-28T20:23:00-CME-001 is associated with M1.0 flare with ID 2022-03-28T19:08:00-FLR-001 which peaked at 2022-03-28T19:23Z.

Both CMEs and associated flares originated from Active Region 12975.
