Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Jun 23 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. No notable flares occurred during the period. No Earth-directed CMEs were 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 (23-25 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 days one and two (23-24 Jun). High levels are forecast for day three (25 Jun) in response to elevated wind speeds from the positive polarity CH HSS feature. 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 indicated a slightly enhanced solar wind environment under the influence of a CIR in advance of a positive polarity CH HSS. Total Field was between 1 and 7 nT while the Bz component reached a low of -5 nT. Phi angle was variable but oriented in a primarily positive solar sector.

Forecast: Solar wind parameters are expected to reflex a continued disturbance as the solar wind environment transitions into the high speed stream of this forecasted feature.

Geospace

24 hr Summary: The geomagnetic field was quiet to unsettled.

Forecast: The geomagnetic field is expected to be at quiet to active levels on days one and two (23-24 Jun) due to CH HSS influence. Quiet to unsettled conditions are expected on day three (25 Jun) as CH HSS effects begin to taper.
