Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 147 Issued at 2200Z on 26 May 2020
IA. Analysis of Solar Active Regions and Activity from 25/2100Z to
26/2100Z: 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 (27 May, 28 May, 29 May).
IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 341 km/s at 26/0612Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 162 pfu.

Experience
Experience is a riverbed, Its source hidden, forever flowing: Its entrance, the
root of the world, The Way moves within it: Draw upon it; it will not run dry.
