COMMENT: Minor MUF depressions to near monthly predicted MUFs 
were observed across Aus/NZ regions on UT day 26 December. Incidence 
of Sporadic E blanketing were mostly confined to Southern Australian 
regions. The two day outlook (27-28 Dec) is for MUFs to be between 
slightly depressed and near monthly predicted levels as the ionosphere 
slowly recovers from the disturbed conditions associated with 
coronal hole.
