Here is the current forecast discussion on space weather and geophysical activity, issued 2021 Jun 11 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Both Regions 2829 (S20W60, Axx/alpha) and 2832 (N14W19, Bxo/beta) were in decay. No Earth-directed CMEs were observed.

Forecast: Solar activity is expected to be very low with a slight chance for C-class flares on 11-13 Jun.

Energetic Particle

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

Forecast: The greater than 2 MeV electron flux is expected to be normal to moderate on 11-13 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 slightly enhanced over the period beginning at approximately 11/0030 UTC when total field increased to 8 nT. During this time, a prolonged period of southward Bz reaching -7 to -8 nT occurred. Solar wind speed remained in the 320-367 km/s range. Phi angle became variable after 11/0050 UTC.

Forecast: Solar wind parameters are expected to be at or near nominal levels on 11-13 Jun.

Geospace

24 hr Summary: The geomagnetic field was quiet to unsettled.

Forecast: The geomagnetic field is expected to be mostly quiet with isolated unsettled periods through the rest on 11 Jun. Mostly quiet conditions are expected on 12-13 Jun.
