A joint report from the USAF and NOAA forecasts low solar activity with a chance of M-class flares and significant geomagnetic field disturbances through August 3, 2026. The report, issued on July 31, 2026, indicates eight numbered sunspot regions are currently visible on the solar disk.
Solar activity is expected to remain low, with a 35% probability of M-class flares occurring daily from August 1st to August 3rd. The geomagnetic field, which has been quiet, is predicted to reach quiet to active levels on August 1st and 3rd, escalating to quiet to major storm levels on August 2nd.
Furthermore, there is a 25% chance of protons greater than 10 MeV crossing the threshold on August 1st, decreasing to 15% on August 2nd. High latitudes face a 50% probability of major-severe geomagnetic storms on August 2nd, highlighting potential impacts on space weather.
