2. FORECAST (23 OCTOBER - 29 OCTOBER) 
MUFS: MUFs near predicted monthly values to 15% enhanced.

Propagation conditions: Normal. SWFs probable due to 
anticipated return of previously flare active solar regions.

T index: 140

3. OUTLOOK (30 OCTOBER - 29 NOVEMBER)
Degraded HF propagation conditions possible:
5 Nov,  7 Nov,  17 Nov.

PLEASE NOTE:
Space weather conditions can frequently be determined by short 
timescale events that cannot be forecast a week in advance,
particularly at solar maximum.
