Here is the current forecast discussion on space weather and geophysical activity, issued 2018 Dec 24 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low and the solar disk remained spotless. A farsided CME, observed in LASCO C2 imagery beginning at 24/0648 UTC, was associated with an eruption beyond the east limb, as seen on STEREO-A 193 imagery at around 24/0600 UTC. Forecast: Solar activity is expected to continue at very low levels on 24-26 Dec.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was at normal to moderate levels and the greater than 10 MeV proton flux was at background levels.

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels on 24-26 Dec and the greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters were at background levels under a nominal solar wind regime.

Forecast: A minor enhancement in the solar wind environment is expected on 24 dec due to the influence of a CH HSS. Background solar wind conditions are expected to prevail on 25-26 Dec.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be quiet to unsetteld on 24 Dec due to CH HSS influence. Generally quiet conditions are expected on 25-26 Dec with the return of a nominal solar wind regime.
