Here is the current forecast discussion on space weather and geophysical activity, issued 2018 Aug 30 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. No spots were observed on the visible disk. There were no Earth-directed CMEs observed in available satellite imagery.

Forecast: Solar activity is expected to be very low for the forecast period (30 Aug - 1 Sep).

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux reached very high levels, with a peak flux of 57,922 pfu observed at 29/1945 UTC. The greater than 10 MeV proton flux was steady at background levels.

Forecast: The greater than 2 MeV electron flux is expected to remain at very high levels on day one (30 Aug), and decrease to high levels for days two and three (31 Aug - 1 Sep). The greater than 10 MeV proton flux is expected to continue at background levels throughout the forecast period.

Solar Wind

24 hr Summary: Solar wind parameters remained slightly enhanced during the period. Solar wind speeds began the period near 530 km/s and steadily decreased to near 440 km/s by the end of the period. Total field averaged around 3 nT, Bz was variable between +/- 2 nT, and the Phi angle was mostly positive, with brief isolated oscillations into the negative sector.

Forecast: Solar wind speeds are expected to undergo minor enhancements due to potential weak influence of a negative polarity CH HSS on days one through three (30 Aug - 01 Sep).

Geospace

24 hr Summary: The geomagnetic field was quiet throughout the period.

Forecast: The geomagnetic field is expected to be at quiet to unsettled levels all three days of the forecast period (30 Aug - 1 Sep).
