Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Jun 25 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Region 2664 (N18E14, Cso/beta) showed signs of growth and consolidation in its intermediate spot group but remained absent of significant flare activity. There were no Earth-directed CMEs observed in available satellite 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 hr 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 hr Summary: Solar wind parameters, as measured by the DSCOVR spacecraft, suggested weak influence from a positive polarity CH HSS. Solar wind speeds increased from starting values near 380 km/s to period ending values at approximately 450 km/s. Total field (Bt) ranged between 3 and 10 nT while the Bz component displayed a maximum southward deflection of -8 nT. Phi was variable but primarily oriented in a positive solar sector throughout 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 on days two and three (26-27 Jun).

Geospace

24 hr Summary: The geomagnetic field was at quiet to unsettled levels with an isolated period of active conditions during the 25/0600-0900 UTC synoptic period.

Forecast: The geomagnetic field is expected to be quiet to unsettled with isolated periods of active conditions on day one (25 Jun) due to weak CH HSS effects. Mostly quiet conditions are expected on days two and three (26-27 Jun) under a nominal solar wind regime.
