:Product: Forecast Discussion :Issued: 2024 Nov 03 0030 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # Solar Activity .24 hr Summary... Solar activity was moderate this period. Region 3869 (S18W60) produced an M1.0 flare at 02/0738 UTC and Region 3878 (N16W03) produced an M1.2 flare at 02/0831 UTC. Minor growth was observed in Regions 3869, 3871 (S09W79), 3878, and 3881 (S09E12). New Regions 3882 (N23W55), 3883 (S06E66), and 3884 (S06E76) were numbered. The remaining regions were stable or in decay. No Earth-directed CMEs were detected in available imagery. .Forecast... M-class flare are likely, with a chance for X-class flares, over 03-04 Nov. There is a chance for M-class flares, and a slight chance for X-class flares, on 05 Nov. Energetic Particle .24 hr Summary... The greater than 10 MeV proton flux was elevated above background levels but remained below S1 (Minor) levels. The greater than 2 MeV electron flux was at normal to moderate levels. .Forecast... There is a chance for the greater than 10 MeV proton flux to reach S1 (Minor) levels on 03-04 Nov. The greater than 2 MeV electron flux is expected to continue at normal to moderate levels through 05 Nov. Solar Wind .24 hr Summary... Solar wind parameters were mildly enhanced. Solar wind speeds slowly increased from 400 km/s to between 450-500 km/s. Total field strength values slowly increased from 8 nT to 12 nT and the Bz component was sustained southward, by as much as -12 nT, between 02/0730-1130 UTC. The phi angle was negative. .Forecast... Enhanced solar wind conditions are likely over 03-04 Nov due to positive polarity CH HSS influences and the possible glancing blow arrival of a CME from 31 Oct. Nominal conditions are expected to return on 05 Nov. Geospace .24 hr Summary... The geomagnetic field reached active levels this period. .Forecast... Periods of active conditions are likely on 03-04 Nov due to positive polarity CH HSS influences and the possible glancing blow arrival of a CME from 31 Oct. Quiet conditions are expected to prevail on 05 Nov.
