Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 106 Issued at 2200Z on 15 Apr 2012
IA. Analysis of Solar Active Regions and Activity from 14/2100Z
to 15/2100Z: Solar activity increased to low levels. Two low-level
C-class flares occurred from a source beyond the northeast limb.
Region 1459 (S16E64) produced occasional B-class flares while it
rotated more fully into view as a Dai-type group with a beta
magnetic classification. Region 1455 (N05W46) showed intermediate
spot development during the period and was classified as a Dsi-type
with a beta magnetic classification. Small Axx-type Region 1454
(S12W00) produced a B9 x-ray flare at 15/0908Z associated with a
slow partial-halo CME, which is not expected to be geoeffective. No
new regions were numbered.
IB. Solar Activity Forecast: Solar activity is expected to be low
through the period (16 - 18 April).
IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z:
Geomagnetic field activity decreased to mostly quiet levels. The
greater than 2 MeV electron flux at geosynchronous orbit was at high
levels throughout the period.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at quiet levels during the period (16 - 18 April).
