634 FXXX12 KWNP 040031 DAYDIS :Product: Forecast Discussion :Issued: 2024 Jul 04 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 reached moderate levels due to an isolated M1.5 flare at 03/0741 UTC from Region 3730 (S18W72, Bxo/beta). Associated with this flare were a Type II radio sweep (1,254 km/s) and a CME off the SW limb at 03/0836 UTC. Initial analysis indicates a miss ahead of Earths orbit. Region 3730 exhibited some decay and redevelopment over the period. Slight growth was observed in Regions 3729 (S05W26, Fai/beta-gamma) and 3733 (N05W29, Cro/beta). New Region 3736 (S18E65, Cso/beta) rotated onto the SE limb and was numbered. No Earth-directed CMEs were observed during the period. .Forecast... Solar activity is expected to be low over 04-06 Jul with a chance for M-class (R1-R2/Minor-Moderate) flares. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux high levels at 03/1840 UTC due to residual effects of previous CME activity. The greater than 10 MeV proton flux was at background levels. .Forecast... The greater than 2 MeV electron flux is expected to reach high levels on 04 Jul and then return to normal to moderate levels on 05-06 Jul. The greater than 10 MeV proton flux is expected to persist at background levels. Solar Wind .24 hr Summary... Solar wind parameters were at nominal levels. Total field ranged from 1-6 nT with the Bz component between +/-5 nT. Solar wind speeds were between ~340-400 km/s. Phi angle was predominantly positive. .Forecast... Solar wind parameters are likely to remain at nominal levels through 06 Jul. Geospace .24 hr Summary... The geomagnetic field was quiet. .Forecast... Mostly quiet, with isolated unsettled periods are expected on 04-06 Jul.
