Here is the current forecast discussion on space weather and geophysical activity, issued 2019 Nov 13 1230 UTC.

Solar Activity

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 2752s magnetic field will likely continue and lead to dissipation.

Energetic Particle

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.

Solar Wind

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.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be primarily quiet 13-15 Nov.
