A joint report from the USAF and NOAA, issued on May 26, 2026, forecasts continued low solar activity with a chance for M-class flares and quiet to active geomagnetic conditions over the next three days.
Solar activity has remained low for the past 24 hours, with nine numbered sunspot regions currently visible on the solar disk. The forecast indicates a 40% probability for M-class flares on May 27, 28, and 29, though the chance for more powerful X-class flares remains low at 5%.
The geomagnetic field has been at quiet to unsettled levels, with solar wind speed peaking at 459 km/s. Protons greater than 10 MeV reached a peak of 23 pfu. The geomagnetic field is expected to be quiet to active on May 27 and 28, returning to quiet levels on May 29, with a slight chance of protons crossing the threshold on May 27.
These forecasts suggest ongoing low-level space weather phenomena, with potential for minor disruptions from M-class flares and fluctuating geomagnetic conditions.
