3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 508 km/s at 29/1514Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 2893 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to minor storm levels on day one (30 Jun) and quiet to active levels on days two and three (01 Jul, 02 Jul). Protons greater than 10 Mev have a slight chance of crossing threshold on day three (02 Jul).
Solar ActivityAnalysis of Solar Active Regions and Activity from 28/2100Z to 29/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 5 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be moderate with a slight chance for an X-class flare on days one, two, and three (30 Jun, 01 Jul, 02 Jul).
