Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 133 Issued at 2200Z on 13 May 2018
IA. Analysis of Solar Active Regions and Activity from 12/2100Z to
13/2100Z: 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 (14 May, 15 May, 16 May).
IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 495 km/s at 13/0001Z. Total IMF reached 11 nT at
13/1348Z. The maximum southward component of Bz reached -5 nT at
13/0538Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 13623 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (14 May, 15 May, 16
May).
