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.
