Prediction for CME (2023-04-24T14:12:00-CME-001)CME Observed Time: 2023-04-24T14:12Z
CME Note: This CME is visible to the south in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is a filament eruption centered around S35W25 starting around 2023-04-24T13:20Z as seen in SDO AIA 131, 171, 193, 304 imagery. An EUV wave is visible at this time in SDO AIA 193, with post eruptive loops forming around 14:00Z. Post eruptive dimming is also visible shortly following the eruption.
CME was not detected at Earth.
Observed Geomagnetic Storm Parameters due to CME:
Predicted Arrival Time: 2023-04-27T07:48Z (-7.0h, +7.0h)
Predicted geomagnetic storm max Kp range due to CME: 4.0 - 6.0
Prediction Method: WSA-ENLIL + Cone (NASA M2M)

Start time of the event: 2023-04-24T14:12Z. Estimated speed: ~583 km/s. Estimated opening half-angle: 44 deg. Direction (lon./lat.): 5/-38 in Heliocentric Earth Equatorial coordinates. Activity ID: 2023-04-24T14:12:00-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 this CME may affect STEREO A. The leading edge of the CME may reach STEREO A at 2023-04-27T04:06Z (plus minus 7 hours). The simulation also indicates that the CME may impact NASA missions near Earth. Simulations indicate that the leading edge of the CME will reach NASA missions near Earth at about 2023-04-27T07:48Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 4-6 (below minor to moderate).
