Product: Forecast Discussion Issued: 2019 Nov 13 1230 UTC Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center
.24 hr Summary… Solar activity remained very low. New NOAA/SWPC Region 2752 (S24E60, Axx/alpha) was assigned; however, the region was inactive, magnetically weak, and already showed signs of decay. No Earth-directed CMEs were observed in available coronagraph imagery.
.Forecast… Very low solar activity is expected to continue 13-15 Nov despite the emergence of new Region 2752. Analysis suggests weakening of Region 2752’s magnetic field will likely continue and lead to dissipation.
.24 hr Summary… The greater than 2 MeV electron flux was normal and the greater than 10 MeV proton flux continued at background values.
.Forecast… The greater than 2 MeV electron flux is expected to remain at normal levels 13-15 Nov and the greater than 10 MeV proton flux is expected to continue at background.
.24 hr Summary… Solar wind parameters were indicative of a return to an ambient, background state and slow solar wind regime. Total IMF strength decreased steadily from 10 nT to 5 nT; while the Bz component was predominantly northward directed. Solar wind speed ranged mainly from 300-350 km/s and the phi angle was primarily in a negative sector.
.Forecast… A slow solar wind environment is expected to continue 13-15 Nov due to a lack of influential features. Minor disturbances and enhancements are possible late on 15 Nov due to proximity of approaching CH HSS influences.
.24 hr Summary… The geomagnetic field was quiet.
.Forecast… The geomagnetic field is expected to be primarily quiet 13-15 Nov.
