IPS HF Communications Warning 27 was issued on 27 July and is 
current for 27-29 Jul.

3. OUTLOOK (05 AUGUST - 04 SEPTEMBER)
Degraded HF propagation conditions possible:

Due to continued low levels of ionising radiation and no significantly active
region expected to return, 
minor to mild degradations in HF conditions are possible throughout this period.
Relatively stronger degradation
are possible on 7 August.

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.
