COMMENT: On the UT day 4 January in the Australian region MUFs
were mostly near monthly predicted values with mild depressions
during the local day. On 5 January similar HF conditions are
expected with possible enhancements at low and middle latitudes
due to the predicted increase in the geomagnetic activity associated
with the coronal hole. Mildly depressed MUFs are expected for
the UT days 6-7 January. HF users are advised to use lower than
the monthly predicted frequencies.
