COMMENT: SWS Preliminary HF Communications Warning 11 was issued 
on 31 January and is current for 2-3 Feb. Australian regional 
maximum usable frequencies (MUFs) were near to 115% above predicted 
monthly values on 2 February, with very strongly enhanced conditions 
observed at Cocos Island. Due to weak overnight geomagnetic activity 
strongly depressed/degraded HF conditions are now not expected, 
with mild to moderately depressed frequencies likely early in 
the UT day 03 February, then recovering. Isolated shortwave fadeouts 
are possible on daylight HF circuits over the next few days.
