COMMENT: On UT day 10 April MUFs were mostly near predicted monthly 
values. There were a few cases of Sporadic E blanketing over 
the Australian Ionosonde sites. The three day outlook (11-13 
April) is for MUFs to be mostly near predicted monthly levels. 
Mild enhancements are also likely on 11 April and mild depressions 
on 12 April in response to the recent increase in geomagnetic 
activity.
