14 Dec   135    Normal           Near to 15% above predicted

COMMENT: Enhanced MUFs observed across all Australian and NZ 
regions over the last 24 hours. Normal to enhanced ionospheric 
support expected for Australian and NZ regions for the next 3 
days due to strong ionising EUV flux (f10.7cm) levels. Possible 
degraded conditions for Antarctic and Southern AUS/NZ regions 
14Dec (during local night) should geomagnetic activity increase.
