2. FORECAST (23 FEBRUARY - 25 FEBRUARY)
Date   T index  Conditions       MUFs                              
23 Feb    -5    Normal           Near predicted monthly values

COMMENT: MUFs were mostly near predicted monthly values for the 
Australian region during the UT day 22 Feb. However periods of 
minor depressions were noted in the Northern Australian region 
during local day time hours. There were a few cases of Sporadic 
E blanketing over the Australian and other Oceanic ionosonde 
sites. For 23-25 Feb, MUFs are expected to be mostly near predicted 
monthly values. Minor to moderate depressions may occur, particularly 
in the Southern hemisphere as a consequence of the minor increase 
in geomagnetic activity and low EUV levels.
