COMMENT: MUFs were variable throughout the northern Australasian 
region and low latitudes during 15 July. Conditions in those 
regions were mostly depressed due to the lack of ionising EUV 
and X-rays from the low spot count on the solar disc. This is 
likely to continue for the next 2-3 days. There were some local 
enhancements at low latitudes and spread F observed,suggesting 
activity in the equatorial anomaly/fountain, probably due to 
thermospheric winds, as geomagnetic activity has been Quiet.
