Date   T index  Conditions       MUFs                              
12 Jul    15    Normal           near predicted monthly values/depressed

COMMENT: Variable MUF depressions of up to around 15% observed 
during both local day and night for Northern AUS/Equatorial regions 
with notable sporadic E at times. Ionosphere continues to remain 
weakly ionised due to very low solar activity. Nearly similar 
HF conditions may be expected on 12 July with some possibility 
of further degradations on 13 and 14 July due to the possibility 
of rise in geomagnetic activity levels from 12 July.
