COMMENT: Some nighttime depressions were observed in Northern 
AUS regions with the daily T index close to long-term predicted 
monthly average but below recent weeks levels. Geomagnetic activity 
early in UT day may account for some of this. As the geomagnetic 
activity was more concentrated in polar regions there was strong 
spread-F observed at some Southern Aus stations such as Hobart. 
Conditions returning to Quiet late in the UT day and expecting 
to continue so the ionosphere will recover to near or slightly 
above predicted monthly medians over the next 3 days.
