COMMENT: The HF propagation conditions were mostly normal during
the UT day 30April at mid-latitudes. Strong enhancements at near-equatorial
northern sites were observed, especially 08-09UT, from an enhanced
equatorial anomaly, possibly caused by remnant activity 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 moderate chance of isolated M/X flares from at least 4 of the
7 solar active regions, which if they occur during local daytime
will cause short wave fadeouts of varying degrees.
