Solar activity has been at moderate levels over the past 24 hours, with nine sunspot regions currently visible on the sun's disk, according to a joint report from the USAF and NOAA. Forecasters anticipate low solar activity in the coming days, but with a chance for M-class flares and a slight chance for X-class flares from June 3rd to June 5th.
The geomagnetic field remained quiet during the last 24-hour period. Solar wind speed peaked at 426 km/s, while total interplanetary magnetic field (IMF) reached 8 nT, and the maximum southward component of Bz was -6 nT. Electrons greater than 2 MeV at geosynchronous orbit peaked at 684 pfu.
Looking ahead, the geomagnetic field is expected to be quiet to unsettled on June 3rd, transitioning to quiet to active levels on June 4th and 5th. Probabilities for M-class flares are 50% daily, with X-class flares at 10% daily for the forecast period. High latitudes face a 30-50% chance of minor storms and a 30-50% chance of major-severe storms over the next three days.
