3-day Solar-Geophysical Forecast
Geophysical Activity	Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic field has been at quiet to severe storm levels for the past 24 hours. Solar wind speed reached a peak of 563 km/s at 18/2211Z according to ACE and DSCOVR, but speeds are likely much higher. Total IMF reached 86 nT at 19/1859Z. The maximum southward component of Bz reached -49 nT at 19/2035Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 36976 pfu at 19/1915Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 7877 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at minor storm to severe storm levels on day one (20 Jan), quiet to minor storm levels on day two (21 Jan) and quiet to unsettled levels on day three (22 Jan). Protons are remained above threshold on day one to three (20-22 Jan).
Solar Activity	Analysis of Solar Active Regions and Activity from 18/2100Z to 19/2100Z: Solar activity has been at moderate levels for the past 24 hours. There are currently 10 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be moderate with a chance for X-class flares on day one (20 Jan) and likely to be moderate with a slight chance for an X-class flare on days two and three (21 Jan, 22 Jan).
