:Product: Forecast Discussion :Issued: 2026 May 02 1230 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # Solar Activity .24 hr Summary... Solar activity was low. Region 4420 (N16W90, Cao/beta) produced an impulsive C7.4/Sf flare at 01/1529 UTC, with associated Type-II radio sweep (est. 593 km/s), as it approached the west limb. Additionally, this region was then also responsible for a C4.0 flare that peaked at 02/1104 UTC and was accompanied by another Type-II radio sweep (est. 641 km/s). Growth was observed in Regions 4424 (N17W56, Eai/beta), 4428 (S23W33, Dai/beta-gamma), 4429 (S04E13, Dsi/beta), and newly-numbered 4431 (S16E46, Dsi/beta). Regions 4430 (N17W38, Cro/beta) and 4432 (N12E61, Axx/alpha) were relatively quiet. Further analysis of a CME that was first seen in C2 coronagraph imagery at approximately 01/1528 UTC determined the event to be a miss well behind Earths orbit. No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is expected to be at low levels with a chance for M-flares (R1-R2/Minor-Moderate) on 02-04 May. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at normal to moderate levels. The greater than 10 MeV proton flux was at background levels. .Forecast... The greater than 2 MeV electron flux is expected to be at normal to moderate levels on 02-04 May. The greater than 10 MeV proton flux is expected to remain at background levels through 04 May. Solar Wind .24 hr Summary... Solar wind parameters remained consistent with ongoing negative polarity CH HSS influences. Total field strength reached a peak of 6 nT, and the Bz component briefly reached -5 nT. Solar wind speeds generally averaged near 450 km/s with lulls between approximately 405-420 km/s. .Forecast... The solar wind environment is expected to remain enhanced under negative polarity CH HSS influences over 02-04 May. Geospace .24 hr Summary... The geomagnetic field ranged from quiet to unsettled levels this period in response to negative polarity CH HSS influences. .Forecast... The geomagnetic field is expected to be quiet and unsettled on 02 and 04 May, with active conditions likely on 03 May, due to continued negative polarity CH HSS influences.
