584 FXXX12 KWNP 060031 DAYDIS :Product: Forecast Discussion :Issued: 2026 Mar 06 0030 UTC # Prepared by the US Dept. of Commerce, NOAA, Space Weather Prediction Center # Product description and SWPC contact on the Web # http://www.swpc.noaa.gov/wwire.html # # Forecast Discussion # Solar Activity .24 hr Summary... Solar activity continued at low levels. Predominently B-class, with isolated C-class, flares were observed. Region 4381 (N08E02, Dai/beta) exhibited moderate growth in its intermediate and trailing spots, and kicked off a C1.8 flare at 05/1950 UTC. New Region 4386 (N16W63, Bxo/beta) was numbered, and was the only other spot group to experience growth during the period. The remaining numbered regions were mostly unchanged and inactive. No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is expected to be at low levels, with a slight chance for isolated M-class activity (R1-R2/Minor-Moderate) through 08 Mar. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at moderate levels with a peak of 581 pfu observed at 05/1440 UTC. The greater than 10 MeV proton flux remained at background levels. .Forecast... The greater than 2 MeV electron flux is to remain at moderate levels 06 Mar before reaching high levels on 07-08 Mar. The greater than 10 MeV proton flux is expected to continue at background levels through 08 Mar. Solar Wind .24 hr Summary... Solar wind parameters were indicative of a near-backgroud solar wind regime. Solar wind speed gradually decreased from ~450 to near 350 km/s by the end of the period. Total magnetic field (Bt) averaged around 5 nT, the North-South (Bz) component was variable between +/-5 nT, and the Phi angle was primarily in a positive (away from the Sun) orientation. .Forecast... Solar wind conditions are expected to continue near ambient levels for the first half of 06 Mar. By late on 06 Mar to early on 07 Mar, the onset of a stronger negative polarity coronal hole high-speed stream (-CH HSS) is anticipated. Geospace .24 hr Summary... The geomagnetic field was at quiet levels. .Forecast... The geomagnetic field is expected to be at mostly quiet levels early on 06 Mar as lingering enhancements subside; G1 (Minor) storming is likely later on 06 Mar due to the anticipated onset of a negative polarity coronal hole high-speed stream (-CH HSS). Active conditions are expected 07-08 Mar as high-speed stream influences continue.
