Forecast Discussion

Product: Forecast Discussion Issued: 2020 Aug 01 0030 UTC Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center
Solar Activity
.24 hr Summary… Solar activity remained very low. A-level enhancements were observed from both Region 2767 (S21W60, Hsx/alpha) and Region 2768 (N26E27, Bxo/beta). Region 2767 remained stable while Region 2768 developed a small trailer spot. No Earth-directed CMEs were observed in available coronagraph imagery.
.Forecast… Solar activity is expected to remain at very low levels for 01 – 03 Aug.
Energetic Particles
.24 hr Summary… The greater than 2 MeV electron flux reached moderate levels and the greater than 10 MeV proton flux remained at background levels.
.Forecast… The greater than 2 MeV electron and 10 MeV proton fluxes are expected to remain below event threshold for 01 – 03 Aug.
Solar Wind
.24 hr Summary… Solar wind parameters, as measured by the DSCOVR spacecraft, continued to reflect nominal conditions. Total magnetic field strength was at or below 5 nT. Solar wind speeds were between 312-381 km/s. Phi angle was variable.
.Forecast… Solar wind parameters are expected to become enhanced on 01-03 Aug due to the anticipated onset of a recurrent, negative polarity CH HSS.
.24 hr Summary… The geomagnetic field was quiet.
.Forecast… The geomagnetic field is expected to be unsettled on 01-03 Aug, with isolated active periods possible 02 Aug, due to CH HSS influence.
