Analysis of Solar Active Regions and Activity from 21/2100Z to 22/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 3 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for a C-class flares on days one, two, and three (23 Jul, 24 Jul, 25 Jul). IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 369 km/s at 22/1230Z. Total IMF reached 8 nT at 21/2137Z. The maximum southward component of Bz reached -6 nT at 22/0003Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one and two (23 Jul, 24 Jul) and quiet to unsettled levels on day three (25 Jul). III.
