Solar activity remained at moderate levels with nine numbered sunspot regions observed, while the geomagnetic field experienced quiet to active conditions over the past 24 hours. Forecasters from the Joint USAF/NOAA Solar Geophysical Activity Report anticipate low solar activity for the next three days, with a 40% daily chance of M-class flares from May 30 to June 1.
The geomagnetic field is expected to continue at quiet to active levels on May 30 and 31, before shifting to quiet to unsettled conditions on June 1. During the analysis period, solar wind speed peaked at 482 km/s, and electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 565 pfu.
Event probabilities indicate a 5-10% chance for minor geomagnetic storms in middle latitudes and a 35% chance in high latitudes over the forecast period. The likelihood of major-severe storms remains low, at 1% for middle latitudes and 30-35% for high latitudes.
