3-day Solar-Geophysical Forecast
Geophysical ActivityGeophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 604 km/s at 15/0705Z. Total IMF reached 9 nT at 15/0633Z. The maximum southward component of Bz reached -6 nT at 14/2329Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 396 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on day one (16 May), quiet to active levels on day two (17 May) and active to minor storm levels on day three (18 May).
Solar ActivityAnalysis of Solar Active Regions and Activity from 14/2100Z to 15/2100Z: Solar activity has been at moderate levels for the past 24 hours. There are currently 3 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 days one, two, and three (16 May, 17 May, 18 May).
