3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 505 km/s at 16/2135Z. Total IMF reached 10 nT at 16/2101Z. The maximum southward component of Bz reached -9 nT at 16/2101Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to minor storm levels on day one (18 Apr) and quiet to unsettled levels on days two and three (19 Apr, 20 Apr). Protons have a slight chance of crossing threshold on days one, two, and three (18 Apr, 19 Apr, 20 Apr).
Solar ActivityAnalysis of Solar Active Regions and Activity from 16/2100Z to 17/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C9 event observed at 17/2004Z from Region 3638 (S17E15). There are currently 12 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 (18 Apr, 19 Apr, 20 Apr).
