Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Jul 24 1230 UTC.

Solar Activity

24 hr Summary: Solar activity remained at very low levels under a spotless 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 (24-26 Jul).

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux was at moderate to high levels with a peak of 5,776 pfu observed at 23/1530 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 (24-26 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 speed began the period near 550 km/s, increased to 707 km/s at 24/0416 UTC and gradually decreased to end the period at about 600 km/s. Total field measurements ranged between 2 and 9 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 (24-26 Jul).

Geospace

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

Forecast: The geomagnetic field is expected to be at predominately quiet to unsettled levels on day one and two (24-25 Jul) as CH HSS influence slowly wanes. Mostly quiet conditions are expected to prevail on day three (26 Jul) as nominal conditions return.
