6 MHz snd 7 MHz midday propagation events

Solar Flux 83; SSN 52 - very low levels as at June 4

The onset of the Melbourne winter has opened up the 6 MHz and 7 MHz bands
for long-distance multihop propagation for the full 24-hrs.

Some interesting occupancies have been observed across our midday period,
corresponding to the solar
transit at 0219 UTC, when the sun is at its highest altitude, at 30 degrees
above the northern horizon.

6 MHz and 7 MHz shortpath signals (night time) from Europe, Africa, ME, and
Africa are dominant up to about 0200, then longpath signals appear around
0200, which then becomes the dominant mode until our mid afternoon. Between
0130 and 0230 both modes are evident. North American signals are also
evident via shortpath across the Pacific at 0200-0230.

Solar Transit 0200-0230:

6020 ALBANIA CRI Cerrick Chinese
6100 FRENCH GUYANA WYFR Montsinery English

7270 ARMENIA VOR Yerevan Russian
7285 MOLDOVA VOR Kishinev Russian
7295 GERMANY R. Farda Biblis Farsi
7305 VATICAN VR SMG Spanish
7360 VATICAN VR SMG English
7365 USA R. Marti Greenville Spanish
7400 ROMANIA RRI Spanish
7440 UKRAINE VOR Kiev English

Channel occupancies will increase during June.

Regards from Melbourne!
