COMMENT: IPS HF Communications Warning 1 was issued on 6 February 
and is current for interval 7 February only (SWFs) . Ionospheric 
conditions in the Australian region were mostly normal over the 
UT day with MUFs near predicted monthly values. An M1 solar flare 
at 2138UT produced a weak short wave fade centred over the Pacific 
affecting HF circuits over that region. The solar active region 
which produced the M-class flare continues to flare and may cause 
further fades in the sunlit hemisphere throughout the day. Otherwise 
expect mostly normal HF conditions 07 Feb with MUFs near predicted 
monthly values.
