Forecast Discussion

Product: Forecast Discussion Issued: 2019 Nov 14 1230 UTC Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center
Solar Activity
.24 hr Summary… Solar activity remained very low and sunspots were no longer present on the visible disk. No Earth-directed CMEs were observed in available coronagraph imagery.
.Forecast… Very low solar activity is expected to continue 14-16 Nov.
Energetic Particle
.24 hr Summary… The greater than 2 MeV electron flux briefly reached moderate levels, but was otherwise normal. The greater than 10 MeV proton flux continued at background values.
.Forecast… The greater than 2 MeV electron flux is expected to continue at normal levels 14-16 Nov and the greater than 10 MeV proton flux is expected to maintain background levels.
Solar Wind
.24 hr Summary… Solar wind parameters were indicative of a slow regime. Total IMF strength was primarily less than 5 nT and the Bz component underwent only weak deviations. Solar wind speed ranged mainly from 325-350 km/s and the phi angle was predominantly negative, but did undergo a few brief deviations into a positive sector.
.Forecast… A slow solar wind regime is anticipated to continue 14-15 Nov. Minor enhancements are possible beginning 16 Nov due to influences of a negative polarity CH HSS.
.24 hr Summary… The geomagnetic field was quiet.
.Forecast… The geomagnetic field is expected to remain quiet 14-15 Nov. Unsettled to active conditions are likely to be reached 16 Nov due to CH HSS effects.
