Yes, sunspot activity remains at ZERO, with no spots having been observed since November 18!
What a disgrace, and users of HF services are getting exasperated at the narrowing frequency window for securing reliable long distance transmission over darkness, or semi-darkness paths.
But let not that worry us unduly, as our monitoring moves to frequency bands which are available!
Here, in Melbourne, the Garden City, there continues to be a very good daytime propagation window open on 6, 7, and 9 MHz from around early to mid-afternoon, from 0300 to about 0500, for
EUROPE/MIDDLE EAST/AFRICA longpath and AMERICAS shortpath
ASIA shortpath propagation remains well and good, between 0300 and 0500 on 7 and 9 MHz.
Higher up, there is intense activity on 11, 13, 15, and 17 MHz in the same time period, which I will not describe in this report.
On Wednesday December 10 I went out to the Doongalla Forest, in the Dandenong Ranges National Park, about 30 mins drive time from here. The Stables Picnic Ground is always excellent for studying propagation, and this day was no exception.
There is very little power line noise, as the nearest overhead transmission lines are about 2 km away, at the Park entrance.
This is a beautiful spot, next to the site of the former Homestead, with many shady trees and flower gardens.
Good walking tracks radiate from the picnic ground, most following old pony trails.
This is a summary of spectrum occupancy, using the Eton E5 with a random wire about 2 m high, 0330-0500!

The data show that despite low sunspot activity, propagation over great distances is excellent, provided that the appropriate frequency band is chosen for research for any given time period.
