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

Solar Activity

24 hr Summary: Solar activity was very low and the solar disk was spotless. No CMEs were observed in coronagraph imagery.

Forecast: Solar activity is expected to be very low on 24-26 Oct.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux reached moderate levels this period and the greater than 10 MeV proton flux was steady at background levels.

Forecast: The greater than 2 MeV electron flux is expected to reach moderate to high levels on 24-26 Oct and the greater than 10 MeV proton flux is expected to persist at background levels throughout the forecast period.

Solar Wind

24 hr Summary: Solar wind parameters were at background levels. Solar wind speeds ended the period less than 375 km/s. Total field was generally less than 5 nT and the Bz component underwent only minor deviations. Phi angle was mostly positive.

Forecast: Conditions are expected to become enhanced due to the anticipated interaction with a recurrent, CH HSS (negative polarity) on 24 Oct. Periods of elevated activity are likely to continue through 26 Oct.

Geospace

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

Forecast: Mostly unsettled levels are expected 24-26 Oct in response to a recurrent CH HSS (negative polarity).
