A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 4 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Dec 03-Dec 05 2018 is 4 (below NOAA
Scale levels).

Solar Activity

.24 hr Summary...
Solar activity was very low under a spotless solar disk. No 
Earth-directed CMEs were observed in available satellite imagery.

.Forecast...
Solar activity is expected to continue at very low levels on 03-05 Dec.

Energetic Particles

.24 hr Summary...
The greater than 2 MeV electron flux continued at normal levels and the
greater than 10 MeV proton flux remained at background values.

.Forecast...
The greater than 2 MeV electron flux is expected to reach moderate to
high levels on days one and two (03-04 Dec) following CH HSS activity.
Normal flux levels are expected on day three (05 Dec) in response to the
the anticipated arrival of the 30 Nov CME. The greater than 10 MeV
proton flux is expected to continue at background levels throughout the
forecast period.

Solar Wind

.24 hr Summary...
Solar wind parameters were enhanced due to the arrival of a CIR in
advance of a positive polarity CH HSS. 

.Forecast...
Enhanced solar wind conditions are expected to prevail throughout the
forecast period due to CH HSS influence and the possible arrival of the
30 Nov CME on day three (05 Dec).

Geospace

.24 hr Summary...
The geomagnetic field was at quiet to unsettled levels, with an
isolated active period.

.Forecast...
The geomagnetic field is expected to be at quiet to active levels
throughout the forecast period (03-05 Dec) in response to CH HSS 
effects and the possible arrival of the 30 Nov CME on day three (05
Dec).

Solar Activity

.24 hr Summary...
Solar activity was very low. The visible disk was spotless. The pair of
CMEs mentioned in the previous discussion product, associated with the
filament eruption centered near S56W09, and occurring at approximately
30/0300 UTC, were analyzed and determined to contain a likely
Earth-directed component. ENLIL modeling suggests a potential arrival
time early on 05 Dec. There were no additional Earth-directed CMEs
observed in available satellite imagery.

CCMC Rules of the Road: CCMC requests that users notify the CCMC, CME model/technique developers and submitting forecasters/researchers before performing event and validation studies with data from the CME Arrival Time Scoreboard. It is recommended that such studies be performed with the knowledge and collaboration of developers and submitting forecasters/researchers.
