Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Jul 25 1230 UTC.

Solar Activity

24 hr Summary: Solar activity remained at very low levels. There were no spotted regions on the visible disk. No Earth-directed CMEs were observed in available satellite imagery.

Forecast: Solar activity is expected to be very low on days one through three (25-27 Jul).

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux was high levels with a peak of 14,800 pfu observed at 24/1720 UTC. The greater than 10 MeV proton flux remained at background levels during the reporting period.

Forecast: The greater than 2 MeV electron flux is expected to reach high levels over the next three days (25-27 Jul). The greater than 10 MeV proton flux is expected to remain at background levels throughout the forecast period.

Solar Wind

24 hr Summary: Solar wind parameters reflected the continued influence of a positive polarity CH HSS. Solar wind speeds remained elevated, averaging around 590 km/s for most of the period. Total field measurements ranged between 1 and 6 nT while the Bz component was variable between +/- 5 nT. The phi angle was in a predominately positive orientation.

Forecast: Solar wind parameters are expected to exhibit a gradual waning trend towards nominal conditions throughout the forecast period (25-27 Jul).

Geospace

24 hr Summary: The geomagnetic field was at quiet to active levels due to continued effects from a positive polarity CH HSS.

Forecast: The geomagnetic field is expected to be at predominately unsettled to active levels on day one (25 Jul) due to continued CH HSS effects. Mostly quiet conditions are expected to prevail on days two and three (26-27 Jul) as nominal conditions return.
