Here is the current forecast discussion on space weather and geophysical activity, issued 2018 Oct 22 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 22-24 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 22-24 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 reflected the waning influence of a positive polarity CH HSS this period.

Forecast: Solar wind parameters are expected to decrease to near-background levels over the course of 22-23 Oct as positive polarity CH HSS influence subsides, and a nominal solar wind regime prevails. Another solar wind enhancement is expected on 24 Oct with the onset of negative polarity CH HSS influence.

Geospace

24 hr Summary: The geomagnetic field was quiet to unsettled this period due to weak CH HSS influence.

Forecast: Quiet conditions are expected for the remainder of 22 Oct through 23 Oct. Quiet to unsettled conditions, with a chance for active leves, are expected on 24 Oct due to the influence of a negative polarity CH HSS.
