COMMENT: Persistent and occasionally intense sporadic-E conditions
observed at all latitudes. Night time spread-F conditions observed
equatorial and polar latitudes. Ocasionally persistent slant-E
conditions observed polar cusp and polar cap stations. Persistent,
severe ionospheric depressions observed at low to mid latitudes
after local dawn and during local day, with briefly enhanced
propagation conditions during local night. Expect continuing
degraded HF conditions due to coronal hole induced geomagnetic
activity. Increased absorption observed around local mid-day
in Antarctic regions.
