Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Jun 28 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Region 2664 (N18W25, Hsx/alpha) underwent decay and was 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 (28-30 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 (28-30 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 were nominal throughout the period. Solar wind speed was between 440 - 475 km/s. Total field strength was between 1 and 5 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 a nominal solar wind environment through day one (28 Jun). Late on day two (29 Jun) and early into day three (30 Jun) 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 day one (28 Jun). Quiet to unsettled conditions are likely late on days two and three (29-30 Jun) due to the anticipated influence from an equatorial, positive polarity CH HSS.
