COMMENT: HF frequencies were overall near monthly medians across
the region, albeit with large variations at near-equatorial latitudes.
Near median MUFs may be expected for the next 2 days before mild
geomagnetic activity from a coronal hole may suppress frequencies
on day 3. There was again extensive Sporadic E-layer activity,
both blanketing F layer and non-blanketing. The strongest blanketing
appeared at higher (southern) latitudes. Similar Sporadic-E may
continue over the next few days.
