Here is the current forecast discussion on space weather and geophysical activity, issued 2021 Jun 14 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Both numbered regions were quiet and stable. No Earth-directed CMEs were identifiable in solar imagery.

Forecast: Solar activity is expected to be very low on 14-16 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 14-16 Jun and the greater than 10 MeV proton flux is expected to persist at background levels.

Solar Wind

24 hr Summary: Solar wind parameters continued to decline to nominal levels over the period. Solar wind speed decreased from approximately 455 km/s to near 390 km/s. Total field ranged from 2-5 nT while the Bz component was between +4/-3 nT. Phi angle was predominantly in a positive sector.

Forecast: Solar wind parameters are expected to return to nominal levels over 14 Jun. On 15 Jun, influence from a negative polarity CH HSS is expected. Enhancements are likely to continue through 16 Jun.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be mostly quiet on 14 Jun. On 15 and 16 Jun, the geomagnetic field is likely to reach active conditions due to influence from a negative polarity CH HSS.
