587 FXXX12 KWNP 070031 DAYDIS :Product: Forecast Discussion :Issued: 2025 Mar 07 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 was at low levels with only low level C-class flaring observed. Slight decay and separation was observed in Region 4012 (S13E07, Eki/beta-gamma). Slight decay was observed in Region 4007 (S11W85, Dso/beta) as it approached the SW limb. The rest of the spotted regions were either stable or in decay. No Earth-directed CMEs were observed. .Forecast... A chance for R1-R2 (Minor-Moderate) radio blackouts, along with a slight chance for an isolated R3 (Strong) event, will persist through 09 Mar primarily due to the flare potential of AR 4012 and the evolution presented by AR 4016. Energetic Particles .24 hr Summary... The greater than 2 MeV electron flux was at normal to moderate levels and the greater than 10 MeV proton flux remained at background levels. .Forecast... The greater than 2 MeV electron flux is expected to be at normal to moderate levels through 09 Mar. The greater than 10 MeV proton flux is expected to remain at background levels through 09 Mar barring a significant eruption. Solar Wind .24 hr Summary... Solar wind parameters were mildly enhanced with solar wind speed ranging from about 435-525 km/s. Total field ranged from 2-8 nT while the Bz component was between +7/-6 nT. Phi angle was mostly positive. .Forecast... A gradual decline of solar wind conditions is anticipated through 07 Mar. CIR influences ahead of a recurrent, negative polarity CH HSS are expected by late 08 Mar through 09 Mar.. Geospace .24 hr Summary... The geomagnetic field was quiet to unsettled. .Forecast... Mostly quiet conditions are expected on 07 Mar as weak, glancing CME effects continue to wane. Unsettled to active levels are expected on 08 Mar as CIR effects ahead of a recurrent, negative polarity CH HSS become geoeffective.
