Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Oct 17 1230 UTC.

Solar Activity

24 hr Summary: Solar activity reached low levels due to C1 and C3 flares observed at 16/1257 UTC and 16/1511 UTC off the SE limb, in the vicinity of Region 2774 (S24, L=313). Associated CMEs were observed in SOHO/LASCO C2 imagery beginning at 16/1325 UTC and 16/1603 UTC, respectively. Due to their location just beyond the SW limb, they are not expected to have a geoeffective component.

Forecast: Solar activity is expected to be very low with a slight chance for C-class flare activity on 17-19 Oct.

Energetic Particle

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

Forecast: The greater than 2 MeV electron flux is expected to be normal to moderate on 17-19 Oct and the greater than 10 MeV proton flux is expected to persist at background levels.

Solar Wind

24 hr Summary: Solar wind parameters were at nominal levels. Solar wind speeds were steady near 300 km/s, total field ranged from 1-9 nT, and Bz reached -4 nT. Phi angle was variable.

Forecast: Solar wind parameters are expected to continue at nominal levels over 17-19 Oct.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be mostly quiet on 17-19 Oct.
