Analysis of Solar Active Regions and Activity from 23/2100Z to 24/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 10 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares on days one, two, and three (25 Jul, 26 Jul, 27 Jul). IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic field has been at unsettled to active levels for the past 24 hours. Solar wind speed reached a peak of 818 km/s at 24/0738Z. Total IMF reached 7 nT at 23/2128Z. The maximum southward component of Bz reached -5 nT at 24/0921Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 2294 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (25 Jul), quiet levels on day two (26 Jul) and quiet to minor storm levels on day three (27 Jul).
