SDF Number 235 Issued at 2200Z on 23 Aug 2019
IA. Analysis of Solar Active Regions and Activity from 22/2100Z to
23/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 0 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (24 Aug, 25 Aug, 26 Aug).
IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 392 km/s at 23/0622Z. Total IMF reached 5 nT at
23/0218Z. The maximum southward component of Bz reached -5 nT at
23/0201Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 528 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (24 Aug, 25 Aug) and quiet to
active levels on day three (26 Aug).
