The Joint USAF/NOAA Solar Geophysical Activity Report, issued at 2200Z on May 10, 2026, indicates high solar activity over the past 24 hours, with five numbered sunspot regions currently visible. Despite this, solar activity is expected to be low in the coming days, though with a notable chance for M-class flares and a slight chance for X-class flares from May 11 to May 13.
Specifically, the report forecasts a 45% probability for M-class flares and a 20% probability for X-class flares each day. The geomagnetic field, which remained at quiet levels during the past 24 hours, is predicted to be quiet to unsettled on May 11 and 13, and quiet on May 12.
Observed solar wind speed reached 504 km/s, and electrons greater than 2 MeV peaked at 409 pfu. Protons also carry a slight chance of crossing threshold levels over the next three days, indicating ongoing space weather dynamics.
