Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 122 Issued at 2200Z on 02 May 2018

IA.  Analysis of Solar Active Regions and Activity from 01/2100Z to
02/2100Z: 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 (03 May, 04 May, 05 May).

IIA.  Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 440 km/s at 01/2150Z. Total IMF reached 6 nT at
02/1058Z. The maximum southward component of Bz reached -4 nT at
02/0630Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 727 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (03 May, 04 May, 05
May).
