SDF Number 227 Issued at 2200Z on 15 Aug 2019
IA. Analysis of Solar Active Regions and Activity from 14/2100Z to
15/2100Z: 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 (16 Aug, 17 Aug, 18 Aug).
IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 510 km/s at 14/2240Z. Total IMF reached 7 nT at
15/2100Z. The maximum southward component of Bz reached -2 nT at
15/1014Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 5234 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (16 Aug) and quiet levels
on days two and three (17 Aug, 18 Aug).
