Predicted Monthly T index for January:  18
2. FORECAST (01 FEBRUARY - 07 FEBRUARY) 
MUFS: MUFs are expected to be near predicted monthly values.
Previous weeks depressed conditions attributed to elevated
geomagnetic activity from coronal hole effects.

Propagation conditions: Normal HF conditions expected.
No SWFs are expected as there are currently no active
solar regions or anticipated returning regions. No
coronal holes present either.

T index:   25

3. OUTLOOK (08 FEBRUARY - 10 MARCH)
Degraded HF propagation conditions possible:
No signficant degraded periods expected.

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.
