Predicted Monthly T index for October:  10
2. FORECAST (18 OCTOBER - 24 OCTOBER) 
MUFS: Possibility of MUF depressions of 10%-20% for the 
entire forecast period. This due to continuation of 
current ionospheric depressions and anticipated rise in
geomagnetic activity from 20Oct-24Oct due to a coronal
hole moving into geoeffective position.

Propagation conditions: Normal-Fair for all latitudes. 
No SWFs expected while there are no active regions on disk.

T index:    5

3. OUTLOOK (25 OCTOBER - 24 NOVEMBER)
Degraded HF propagation conditions possible:
28-Oct,09-Nov,11-Nov,17-Nov.

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.
