On the Boardwalk, near the monitoring site!
This is a summary of notable frequency occupancies observed in the mid-afternoon, 0330 to 0400 on January 27, 2017, at one of my favourite field sites, in Westerfolds Park, at Templestowe, in Melbourne's outer east.
Receiver was the little Eton E5, with two metres of antenna. Some good E-mode propagation from Asia and Pacific apparent.

Spectrum Research - 9 MHz

Solar activity remains very low, according to the Department nt of Meteorology (Australian Government), with the 10.7 cm Solar Radio Flux at 84, and the Daily Equivalent Sunspot Number down to 26.
Those indices are expected;ected to drop even further in coming days.
This means that long-haul, mufti-hop propagation following darkness or semi-darkness paths on frequencies above about 14 MHz will continue to be unreliable.
Research of frequency usage in the 9 MHz region on January 24, 2017, revealed these notable occupancies, here in Melbourne, across the time span 1900 to 1930.

To all members and readers!
Here in Melbourne, our sunrise and sunset times have started to changed due to later sunrises and earlier sunsets. This altered pattern has resulted in variations in signal fade-in and fade-out timings, particularly on the 6, 7 and 9 MHz bands.
Propagation patterns have also changed, due to the continuing low level of Solar Activity, with the daily Equivalent Sunspot Number falling to as low as zero on some days!
This is a summary of notable frequency occupancies researched on January 9 2017,  across the time span 1930 to 2000.

Monitoring Research

Solar activity continues to be very low, with the 10.7 Solar Radio Flux having dropped to 74 and the Daily Equivalent Sunspot Number down to 11.
These numbers are not expected to change significantly in the immediate future, meaning that long-haul multi-hop propagation on darkness or semi-darkness paths on frequencies above about 13 MHz will continue to be unreliable.
Here in Melbourne, there has been good propagation on 7 and 9 MHz in our sunrise period, from Europe, Africa, Asia the ME and the Americas.
The summary which follows indicates notable occjupancies in the period 1900 to 1930, on December 27, 2016.
