Rationale: No G1 (Minor) or greater geomagnetic storms are expected. No
significant transient or recurrent solar wind features are forecast.
B. NOAA Solar Radiation Activity Observation and Forecast
Solar radiation, as observed by NOAA GOES-15 over the past 24 hours, was
below S-scale storm level thresholds.

Dec 13 Dec 14 Dec 15
S1 or greater 1% 1% 1%
Rationale: No S1 (Minor) or greater solar radiation storms are expected.
No significant active region activity favorable for radiation storm
production is forecast.
C. NOAA Radio Blackout Activity and Forecast
No radio blackouts were observed over the past 24 hours.

Extended Space Weather Discussion:
Solar Activity
.24 hr Summary...
Solar activity was very low. No Earth-directed CMEs were observed in
available satellite imagery.
.Forecast...
Solar activity is expected to continue at very low levels on 13-15 Dec.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux ranged from normal to high levels,
today. The greater than 10 MeV proton flux remained at background
values.
.Forecast...
The greater than 2 MeV electron flux is expected to be at moderate to
high levels on 13-15 Dec. The greater than 10 MeV proton flux is
expected to continue at background levels.
Solar Wind
.24 hr Summary...
Solar wind parameters were at ambient conditions. Solar wind speed
decreased to near 400 km/s. Total field strength remained less than 5 nT
during the period. Bz ranged between +/- 3nT. Phi angle was mostly
oriented in a negative solar sector.
.Forecast...
Nominal levels is expected for 13-15 Dec.
Geospace
.24 hr Summary...
The geomagnetic field was at quiet levels.
.Forecast...
A return to quiet conditions is expected for 13-15 Dec.
