Here is the current forecast discussion on space weather and geophysical activity, issued 2019 Sep 11 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was at very low levels. The solar disk was spotless. No Earth-directed CMEs were observed in available imagery.

Forecast: Solar activity is expected to be at very low on 11-13 Sep.

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux reached high levels. The greater than 10 MeV proton flux was at background levels.

Forecast: The greater than 2 MeV electron flux is expected to be at high levels on 11-13 Sep in response to recent CH HSS influence. The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters were slightly enhanced. Solar wind speeds decreased from around 500 km/s to around 450 km/s by periods end. Total field ranged between 4-6 nT, and the Bz component reached a brief, southward deflection of -4 nT. The phi angle was predominantly positive with brief deviations into a negative orientation.

Forecast: Solar wind parameters are expected to be at ambient conditions on 11-13 Sep.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be mostly quiet 11-13 Sep.
