Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 174 Issued at 2200Z on 22 Jun 2012
IA. Analysis of Solar Active Regions and Activity from 21/2100Z
to 22/2100Z: Solar activity has been very low. New Region 1511
(N15W17) was numbered.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low during the period. Region 1511 is capable of isolated
C-class flare production.
IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z:
Geomagnetic field activity was at quiet levels. The greater than 2
MeV electron flux at geosynchronous orbit was at high levels
throughout the period.
IIB. Geophysical Activity Forecast: Geomagnetic activity is
expected to be mostly quiet for the next three days (23 - 25 June).
