Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 140 Issued at 2200Z on 20 May 2018
IA. Analysis of Solar Active Regions and Activity from 19/2100Z to
20/2100Z: 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 (21 May, 22 May, 23 May).
IIA. Geophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 444 km/s at 20/1533Z. Total IMF reached 5 nT at
20/0220Z. The maximum southward component of Bz reached -4 nT at
20/0510Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 626 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (21 May, 22 May) and quiet to
active levels on day three (23 May).
