Here is the current forecast discussion on space weather and geophysical activity, issued 2021 Jun 26 1230 UTC.

Solar Activity

24 hr Summary: Solar activity reached low levels. Region 2833 (N24, L=207) produced a C1 flare at 25/1403 UTC, along with B-class flare activity, as it transited the west limb. Newly numbered Region 2835 (S17E59, Dso/beta) produced only B-class flare activity. No Earth-directed CMEs were observed in coronagraph imagery. Forecast: Solar activity is expected to be very low over 26-28 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 at background levels.

Forecast: The greater than 2 MeV electron flux is expected to be normal to moderate over 26-28 Jun and the greater than 10 MeV proton flux is expected to remain at background levels.

Solar Wind

24 hr Summary: Solar wind parameters were at nominal levels. Solar wind speeds varied between 350-425 km/s. Total field strength averaged near 5 nT and Bz was at around +/- 4 nT. The phi angle was predominantly positive. Forecast: An ambient solar wind environment is expected to persist over 26-28 Jun.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be mostly quiet over 26-28 Jun.
