Date   T index  Conditions       MUFs                              
07 May    65    Normal           Near predicted monthly values

COMMENT: Maximum Usable Frequencies (MUFs) in the Australian 
region were largely near predicted values during local daylight 
hours on UT day 06-May. Some depressions of 15% were observed 
in the southern Australian region as well as at Niue Island during 
local night hours. Spread-F was also observed during local night 
hours at Hobart and Learmonth. MUFs are expected to remain near 
predicted values for 07-May, with some depressions of 10-15% 
possible on 08-May due to forecast geomagnetic activity. These 
are forecast to begin recovering toward predicted values over 
09-May.
