3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 17/2100Z to 18/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 557 km/s at 18/2042Z. Total IMF reached 10 nT at 18/0540Z. The maximum southward component of Bz reached -7 nT at 18/1011Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 892 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (19 Jun), quiet to minor storm levels on day two (20 Jun) and quiet to unsettled levels on day three (21 Jun). Protons have a slight chance of crossing threshold on days one, two, and three (19 Jun, 20 Jun, 21 Jun).
Solar ActivityAnalysis of Solar Active Regions and Activity from 17/2100Z to 18/2100Z: Solar activity has been at high levels for the past 24 hours. There are currently 6 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be moderate with a chance for X-class flares on days one, two, and three (19 Jun, 20 Jun, 21 Jun).
