COMMENT: Overall, MUFs over the Australian region were slightly
depressed to near monthly predicted levels on UT day 03 Oct.
The highest MUF depression of 20% - 35% below monthly predicted
levels occurred over the Niue island and North Australian regions.
In contrast, the strongest MUFs of 30% above monthly predicted
levels occurred over the Antarctic during morning. The outlook
for today (UT day 04 Oct) is for the MUFs to be mostly near monthly
predicted values. Depressed MUFs are expected to begin from UT
day 05 Oct in response to the likely disturbed geomagnetic conditions
associated with the coronal hole.
