Here is the current forecast discussion on space weather and geophysical activity, issued 2016 Sep 17 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was at very low levels. Region 2592 (N14E46, Bxo/beta) produced only B-level activity throughout the period. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is expected to be very low throughout the forecast period (17-19 Sep).

Energetic Particle

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

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels for the forecast period (17-19 Sep). The greater than 10 MeV proton flux is expected to remain at background levels throughout the forecast period.

Solar Wind

24 hr Summary: Solar wind parameters were at near-background levels. Solar wind speed fluctuated between 280-350 km/s. Total magnetic field strength was variable between 3 nT and 9 nT. The Bz component was variable with a maximum southward deviation of -4 nT. Phi angle was predominately negative.

Forecast: Solar wind parameters are expected to continue at background levels on days one and two (17-18 Sep). Enhanced conditions are expected on day three (19 Sep) due to the onset of a recurrent CH HSS. Solar wind speeds in the 550-600 km/s range are anticipated.

Geospace

24 hr Summary: The geomagnetic field was at quiet to unsettled levels.

Forecast: The geomagnetic field is expected to be mostly quiet on days one and two (17-18 Sep). Quiet conditions are expected early on day three (19 Sep), increasing to unsettled to active conditions midday with isolated G1 (Minor) storm conditions likely due to influence from a recurrent, negative polarity CH HSS.
