COMMENT: IPS HF Communications Warning 16 was issued on 26 February 
and is current for interval 27-29 February (SWFs) . HF conditions 
mostly near normal. Major solar flares from Active Region 564 
at 0200 and 2220UT resulted in brief short-wave fadeout conditions 
in the Australasian region. Although this region is favourably 
positioned on the solar disk, no further geophysical consequence 
is anticipated from these events. The region maintains good potential 
for further flare activity. HF communicators are advised to monitor 
the IPS website for notification of further flare activity over 
the next few days. There is a possibility of slightly degraded 
HF conditions after day three due to a recurrent coronal hole 
wind stream.
