Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Jun 22 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. No notable flares occurred during the period. The three numbered regions on visible disk were all H-type spots and showed little growth or decay. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is expected to be very low with a slight chance for C-class flares over the next three days (22-24 Jun).

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux reached high levels. The greater than 10 MeV proton flux remained at background levels.

Forecast: The greater than 2 MeV electron flux is expected to reach high levels for day one (22 Jun). A decrease to moderate levels is forecast for days two and three (23-24 Jun), with the expected onset of CIR effects prior to a CH/HSS. 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 continued ambient background conditions. Solar wind velocities were near 300 km/s. Total Field was between 4 and 7 nT while the Bz component was between +/-5 nT. Phi angle was oriented in a negative sector.

Forecast: Solar wind parameters are expected to show disturbances later in the day on day one (22 Jun) as the onset of a CIR prior to a positive polarity CH HSS. A transition into the high speed stream from this feature is forecast for days two and three (23-24 Jun).

Geospace

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

Forecast: The geomagnetic field is expected to be quiet to unsettled on day one (22 Jun), due to anticipated CIR effects. Quiet to active conditions are expected on days two and three (23-24 Jun) due to transition into CH influence.
