SDF Number 210 Issued at 2200Z on 28 Jul 2020
IA. Analysis of Solar Active Regions and Activity from 27/2100Z to
28/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 1 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (29 Jul, 30 Jul, 31 Jul).
IIA. Geophysical Activity Summary 27/2100Z to 28/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 443 km/s at 27/2207Z. Total IMF reached 5 nT at
27/2122Z. The maximum southward component of Bz reached -4 nT at
27/2200Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 323 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (29 Jul, 30 Jul, 31
Jul).
