Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 140 Issued at 2200Z on 19 May 2012
IA. Analysis of Solar Active Regions and Activity from 18/2100Z
to 19/2100Z: Solar activity was low. Only a few weak C-class flares
were observed from old Region 1476 (N10, L=180) and Region 1479
(N15W39). No Earth-directed CMEs were observed during the reporting
period.
IB. Solar Activity Forecast: Solar activity is expected to continue
at low levels with a slight chance for an M-class flare on days 1 -
3 (20 - 22 May).
IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z:
The geomagnetic field was quiet. The greater than 10 MeV proton
event at geosynchronous orbit that began at 17/0210Z and reached a
peak flux of 255 pfu at 17/0430Z, ended at 18/1620Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at mostly quiet levels on day 1 (20 May). Quiet to
unsettled levels are expected on day 2 (21 May). Quiet to unsettled
levels with isolated active periods are expected on day 3 (22 May)
as a coronal hole high speed stream and the 18 May CME are expected
to become geoeffective.
III. Event Probabilities 20 May-22 May
