COMMENT: MUFs were near predicted monthly values across the centre
and south of the region during the last 24 hours but returned
to variable in the north near the active equatorial anomaly.
The anomaly was possibly made more active by Unsettled geomagnetic
conditions from the passage 0030UT of a weak shock in the wake
of the CME on the 12th. Geomagnetic activity is continuing with
sustained Bz southwards so variability should persist into the
14th.
