COMMENT: The HF propagation conditions were mostly normal during 
UT day, 28 April across mid-latitudes. Enhancements at near-equatorial 
Niue Island station were possibly caused by remnant activity 
in the equatorial anomaly/fountain after the geomagnetic disturbances 
of the previous days. Expect mostly normal HF frequency availability 
for next three days in the absence of significant geomagnetic 
or solar flare activity. There is a chance of isolated M/X flares 
from four of the solar active regions, which if they occur during 
local daytime will cause short wave fadeouts of varying degree.
