213 FXXX12 KWNP 021231 DAYDIS :Product: Forecast Discussion :Issued: 2024 Jul 02 1230 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. Region 3729 (S05W05, Eai/beta-gamma) and a Region just beyond the SE limb near S17 were responsible for multiple low level C-class flares. The largest was a C3.6 at at 01/2233 UTC from just beyond the SE limb. Slight growth was observed in Region 3729. The rest of the spotted regions were either stable or gradually decaying. At approximately 01/1124 UTC a southwesterly CME associated with the an M2.1 flare was first observed in C2 coronagraph imagery. This relatively narrow CME was modeled and determined to be ahead of Earths orbit. No other potentially Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is expected to be low over 02-04 Jul with a chance for M-class (R1-R2/Minor-Moderate) flares. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at normal to moderate levels and the greater than 10 MeV proton flux was at background levels. .Forecast... The greater than 2 MeV electron flux is expected to continue at normal to moderate levels on 02-04 Jul and the greater than 10 MeV proton flux is expected to persist at background levels. Solar Wind .24 hr Summary... Solar wind parameters decreased to nominal levels. Solar wind speed decreased from 515 km/s to near 415 km/s. Total field was steady at 2-3 nT while the Bz component was between +/-2 nT. Phi angle was predominantly positive. .Forecast... Enhanced solar wind conditions are expected to return on 03-04 Jul due to the anticipated arrival of multiple CMEs that left the Sun between 26-29 Jun. Geospace .24 hr Summary... The geomagnetic field was quiet. .Forecast... The geomagnetic field is expected to be quiet to unsettled for the rest of 02 Jul. Unsettled to active levels are anticipated on 03-04 Jul with isolated minor storm periods likely on 03 Jul due to the anticipated arrival of multiple CMEs that departed the Sun between 26-29 Jun.
