Here is the current forecast discussion on space weather and geophysical activity, issued 2018 Dec 12 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. A new active region was numbered today near N08E11 with NOAA sunspot number 2730, then immediately decayed into a plage region. No Earth-directed CMEs were observed in available satellite imagery.

Forecast: Solar activity is expected to continue at very low levels on 12-14 Dec.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux ranged from normal to high levels, today. The greater than 10 MeV proton flux remained at background values.

Forecast: The greater than 2 MeV electron flux is expected to be at moderate to high levels on 12-14 Dec. The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters continued to wane toward near ambient conditions. Solar wind speed decreased from near 510 to 450 km/s. Total field strength remained around 5 nT during the period. Bz ranged between +/- 4 nT. Phi angle was mostly oriented in a negative solar sector.

Forecast: A return to nominal levels is expected for 12-14 Dec.

Geospace

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

Forecast: A return to quiet conditions is expected for 12-14 Dec.
