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

Solar Activity

24 hr Summary: Solar activity was very low. Regions 2841 (S18E38, Axx/alpha) and 2842 (N24E72, Hsx/alpha) were unremarkable and absent of significant flare activity. No Earth-directed CMEs were observed in available imagery.

Forecast: Solar activity is expected to be very low on 11-13 Jul.

Energetic Particles

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

Forecast: The greater than 2 MeV electron flux is expected to continue at normal to moderate levels on 11-12 Jul. Moderate to high levels are likely on 13 Jul due to CH HSS influence. The greater than 10 MeV proton flux is expected to remain at background levels.

Solar Wind

24 hr Summary: Solar wind parameters reflected background conditions.

Forecast: By mid to late on 11 Jul, parameters are expected to become enhanced due to the arrival of a negative polarity CH HSS. HSS conditions are expected to continue through 13 Jul.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: Mostly quiet conditions are expected through mid to late on 11 Jul. Unsettled levels are expected late on 11 Jul followed by unsettled to active levels on 12-13 Jul due to CH HSS effects.
