COMMENT: MUFs were mostly near predicted monthly values for most
AUS/NZ regions on UT day 23 May. Expect mostly near predicted
monthly values for the next three days (24 - 26 May). The ionospheric
support is expected to be weakest today, but still near monthly
predicted levels. These are the aftermath of the observed minor
magnetic disturbances associated with the passage of the polar
coronal hole.
