COMMENT: IPS SWF HF Communications Warning 16 was issued on 28 
February and is current for 1-3 Mar. Numerous active regions 
on the disc are emitting C-class flares, and strong background 
ionising flux. AR1990/91 still hold food M flare potential for 
moderate short-wave fadeouts (SWFs). AR1982 has rotated off the 
disc so overall M flare potential has dropped slightly. Observed 
MUF's for most of Australasia were above monthly median values 
during the day and night due to increased ionising EUV/X-ray 
enhanced by numerous active regions on the disc and transport 
of ionisation from dayside to nightside by thermospheric winds. 
Expect this trend to continue for the next three days.
