Solar Activity

24 h Summary
Solar activity was very low. Region 2664 (N18E32 Cao/beta) developed a leader and intermediate spots over the past 24 hours. Region 2662 (N13W77, Axx/alpha) was slowly decayed. There were no Earth-directed CMEs observed in available coronagraph imagery.
Forecast
Solar activity is expected to be very low with a slight chance for C-class flares over the next three days (25-27 Jun).

Energetic Particles

24 h Summary
The greater than 2 MeV electron flux was at normal to moderate levels. The greater than 10 MeV proton flux remained at background levels.
Forecast
The greater than 2 MeV electron flux is expected to persist at normal to moderate levels for the next three days (25-27 Jun). The greater than 10 MeV proton flux is expected to persist at background levels throughout the forecast period.

Solar Wind

24 h Summary
Solar wind parameters, as measured by the DSCOVR spacecraft, suggested weak influence from a positive polarity CH HSS. Total magnetic field strength ranged 5-8 nT. The Bz component was variable with a maximum southward deflection of -6 nT. Solar wind speeds ranged from 370-425 km/s. Phi was predominantly positive over the reporting period.
Forecast
Solar wind parameters are expected to reflect decreasing influence from the positive polarity CH HSS on day one (25 Jun). A nominal solar wind environment is expected over days two and three (26-27 Jun).

Geospace

24 h Summary
The geomagnetic field was at quiet to unsettled levels.
Forecast
The geomagnetic field is expected to be quiet to unsettled on day one (25 Jun) due to weak CH HSS effects. Quiet conditions are expected over days two and three (26-27 Jun) under a nominal solar wind regime.
Current data suggest that it is not possible to see aurora now at middle latitudes
