Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Jun 30 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was at very low levels. Region 2664 (N18W52, Hsx/alpha) continued its decaying trend and produced no flare activity over the past 24 hours.

Forecast: Solar activity is expected to continue at very low levels with a slight chance for C-class flares all three days (30 Jun-02 Jul).

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux continued at normal to moderate levels and the greater than 10 MeV proton flux remained at background values.

Forecast: The greater than 2 MeV electron flux is expected to continue at normal to moderate levels all three days (30 Jun-02 Jul) and the greater than 10 MeV proton flux is expected to remain at background levels.

Solar Wind

24 hr Summary: Solar wind parameters indicated nominal conditions. Total magnetic field strength ranged from 3-6 nT and the Bz component reached a maximum southward deflection of -5 nT. Solar wind speeds steadily declined from 450 km/s to near 340 km/s by the periods end. Phi angle was predominantly oriented in the positive sector.

Forecast: Solar wind parameters are expected to remain at near-background levels on days one and two (30 Jun - 01 Jul). An enhancement is anticipated late on day three (02 Jul) due to the arrival of the 28 June CME.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be mostly quiet over days one and two (30 Jun-01 Jul). Unsettled to active conditions are expected late on day three (02 Jul) due to the anticipated arrival of the 28 June CME.
