Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 145 Issued at 2200Z on 25 May 2018
IA. Analysis of Solar Active Regions and Activity from 24/2100Z to
25/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 2 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares on days one, two, and three (26 May,
27 May, 28 May).
IIA. Geophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 449 km/s at 24/2211Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 197 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (26 May, 27 May) and quiet to
unsettled levels on day three (28 May).
