The latest Joint USAF/NOAA Solar Geophysical Activity Report forecasts low solar activity with a 40% chance of M-class flares over the next three days, while geomagnetic conditions are expected to remain quiet to active.
Solar activity has been low for the past 24 hours, with nine sunspot regions currently visible on the solar disk. The forecast indicates a continued low level of activity, though the probability of M-class flares is 40% for May 31, June 1, and June 2.
Geophysical conditions have ranged from quiet to active. Solar wind speed peaked at 576 km/s, and electrons greater than 2 MeV reached 408 pfu. The geomagnetic field is predicted to be quiet to active on May 31 and June 1, transitioning to quiet levels on June 2. Middle latitudes have a 30% chance of active conditions on May 31 and June 1, while high latitudes face a 40% chance of major-severe storms on May 31.
