Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Jun 27 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Region 2664 (N18W13, Dsi/beta) was stable and inactive. 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 (27-29 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 (27-29 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, indicated continued waning influence from a positive polarity CH HSS. Solar wind speed gradually decreased from near 550 km/s to 450 km/s by periods end. Total field strength was between 1 and 6 nT while the Bz component dropped as low as -3 nT. Phi angle was predominantly positive throughout the reporting period.

Forecast: Solar wind parameters are expected to reflect recovery from the positive polarity CH HSS early on day one (27 Jun), returning to a nominal solar wind environment. Nominal conditions are expected to continue into day two (28 Jun) and early into day three (29 Jun). Later on day three there will likely be a minor enhancement from a positive polarity CH HSS.

Geospace

24 hr Summary: The geomagnetic field was at quiet levels.

Forecast: The geomagnetic field is expected to be mostly quiet for days one and two (27-28 Jun) due to waning CH HSS effects. Quiet to unsettled conditions are likely late on day three (29 Jun) due to the anticipated influence from an equatorial, positive polarity CH HSS.
