Here is the current forecast discussion on space weather and geophysical activity, issued 2021 Jun 05 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low with both regions 2827 (N12W49, Hsx/alpha) and 2829 (S18E17, Cao/beta) producing B-flares. Slight decay was observed in the trailing spots of Region 2827. Region 2829 grew initially with the addition of several new trailing spots, but appeared to be in decay towards the second half of the period. No Earth-directed CMEs were observed.

Forecast: Solar activity is expected to be very low, with a chance for C-class flares, on 05-07 Jun.

Energetic Particle

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

Forecast: The greater than 2 MeV electron flux is expected to be normal to moderate over 05-07 Jun 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 nominal levels with solar wind speed ranging from 307-439 km/s. Total field ranged from 1-6 nT while the Bz component was between +/-4 nT. Phi angle was predominantly in a positive sector.

Forecast: Solar wind parameters are expected to be near nominal levels on 05-07 Jun.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be mostly quiet on 05-07 Jun.
