Here is the current forecast discussion on space weather and geophysical activity, issued 2020 Aug 31 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. The visible disk was spotless. An eruptive filament was observed in SDO/AIA 304 imagery beginning at 30/2258 UTC centered near N32E48. A likely associated CME was observed in SOHO/LASCO C2 imagery off the east limb beginning at 31/0336 UTC. Analysis will be performed as further imagery becomes available.

Forecast: Solar activity is expected to persist at very low levels on 31 Aug-02 Sep.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux reached high levels this period with a peak flux of 2,800 pfu observed at 30/1845 UTC. The greater than 10 MeV proton flux was steady at background levels throughout the period.

Forecast: The greater than 2 MeV electron flux is expected to reach high levels on 31 Aug-02 Sep 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 under the influence of a positive polarity CH HSS. Solar wind speed increased from 433 km/s to a maximum of 608 km/s at 31/0841 UTC. Total field ranged from 2-8 nT while the Bz component was between +6/-7 nT. Phi angle was oriented in a positive (away) solar sector.

Forecast: Solar wind parameters are expected to remain enhanced on 31 Aug and slowly wane on 01 Sep. Another positive polarity CH HSS is expected to become geoeffective on 02 Sep causing further enhancement of the solar wind.

Geospace

24 hr Summary: The geomagnetic field was at quiet to G1 (minor) storm levels due to CH HSS activity.

Forecast: The geomagnetic field is expected to be at quiet to active levels on 31 Aug as HSS effects persist. Quiet to unsettled levels are expected on 01 Sep. On 02 Sep, another positive polarity CH HSS is expected to become geoeffective causing unsettled to active levels.
