Prediction for CME (2024-03-05T21:24:00-CME-001)CME Observed Time: 2024-03-05T21:24ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/29475/-1 CME Note: This CME is visible to the south/southeast in SOHO LASCO C2, C3 and after a data gap in STEREO A COR2 imagery. The CME appears to have a bright core in initial frames before fading as it progresses throughout the SOHO LASCO C3 field of view. The source is a filament eruption centered around S40E35, but stretches between S25E20 to S55E50 with a southern deflection as it erupts. The eruption begins around 2024-03-06T20:00Z in SDO/AIA and GOES SUVI 304 with associated dimming visible in SDO/AIA 193, brightening in SDO/AIA 304, and minor moving/opening field lines in GOES SUVI 284. A brief post-eruptive arcade is also visible in SDO/AIA 171 and 193 starting around 2024-03-06T00:00Z. CME was not detected at Earth.

The CME associated with a filament eruption centered near S35E40 that was observed in coronagraph imagery starting at 05/2136 UTC was analyzed and indicated most of the ejecta is likely south and behind Earth's orbit. However, a portion of the ejecta could slightly graze the Earth late on 08 Mar into early 09 Mar. Solar Wind .Forecast... Solar wind parameters are expected to remain near nominal levels on 07-08 Mar. Enhancements in the solar wind environment are then possible late on 08 Mar as a small, negative polarity CH HSS combines with the anticipated arrival of a CME that left the Sun on 05 Mar. Geospace .Forecast... Quiet to unsettled conditions are expected on 07-08 Mar, with a chance for isolated active periods late on 08 Mar. The increase in activity is due to the possible combined effects from a weak, negative polarity CH HSS and the anticipated grazing impacts from the CME that left the Sun on 05 Mar. Conditions are then expected to increase to unsettled to active levels, with likely periods of isolated G1 (Minor) geomagnetic storming on 09 Mar as the CME effects increase. ---------------------- :Product: NOAA 3-day Geomagnetic Forecasts :Issued: 2024 Mar 06 2200 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # NOAA Ap Index Forecast Observed Ap 05 Mar 007 Estimated Ap 06 Mar 008 Predicted Ap 07 Mar-09 Mar 008-015-020 NOAA Geomagnetic Activity Probabilities 07 Mar-09 Mar Active 10/35/35 Minor storm 05/25/35 Moderate storm 01/10/15 Strong-Extreme storm 01/01/01 NOAA Kp index forecast 07 Mar - 09 Mar Mar 07 Mar 08 Mar 09 00-03UT 2.33 2.33 3.67 03-06UT 2.00 2.00 4.67 06-09UT 2.00 2.00 3.67 09-12UT 2.00 3.00 3.33 12-15UT 2.00 3.00 3.33 15-18UT 2.00 3.33 3.33 18-21UT 2.00 3.33 2.67 21-00UT 2.33 4.33 2.33 ---------------------- Product: 3-Day Forecast Issued: 2024 Mar 07 1230 UTC Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center A.
