2. FORECAST (05 AUGUST - 11 AUGUST) 
Maximum Usable Frequencies (MUFs) will be near predicted monthly 
values on all days this week, with some mild depressions possible 
over 07-08 Aug due to forecast minor geomagnetic activity. 

Propagation conditions: Gloabl Ionospheric conditions are expected 
to be Normal across 05-11 Aug, with some mild degradations possible 
in high latitude regions over 07-08 Aug.

T index: 64

3. OUTLOOK (12 AUGUST - 11 SEPTEMBER)
Degraded HF propagation conditions possible:
17-19 Aug

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.
