Predicted Monthly T index for December:  18
2. FORECAST (14 DECEMBER - 20 DECEMBER) 
MUFS: MUF's are expected to be near predicted monthly
values. Previous weeks HF disturbances and lower MUF's
due to enhanced geomagnetic activity from coronal hole
effects that have subsided.

Propagation conditions: Normal HF conditions are expected.
No large or active solar regions are currently on disc. No
SWFs expected due to low solar activity.

T index:   25

COMMENT: IPS HF Communications Warning 46 was issued on
11 December and is current for interval  11-14 December. 
3. OUTLOOK (21 DECEMBER - 20 JANUARY)
Degraded HF propagation conditions possible:
27-Dec to 30-Dec, 5-Jan to 7-Jan.

PLEASE NOTE:
At this time of the solar cycle, space weather conditions
are frequently determined by short timescale events, not
able to be forecasted a week in advance.
