COMMENT: On UT day 26 January, MUFs were slightly depressed over
most Australian region as the aftermath of the recent geomagnetic
disturbance associated with the coronal hole and very low levels
of ionising radiation from the Sun. Near predicted to depressed
MUFs are expected for the next three UT days, 27-29 January,
as a consequence of very low levels of ionising radiation from
the Sun.
