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.
