7 MHz propagation notes 9.30 am to 10 am

Solar noon is now at 22 minutes past  local noon here in Melbourne, 0222 UTC), when the sun's altitude is only 28.8 degrees above the horizon. Probably not even worth the sun rising at all, as we are only given 9 hrs and 32 mins of daylight now, in the lead-up to the shortest day on Jun 21!
 
This daytime sunlight pattern affects propagation into Melbourne, with later fade-out and earlier fade in times as we move into winter.
 
Morning sigs on 7 MHz are dominant between 9 am and 10 am (2300-0000) – this table denotes the pattern on June 18 2013 up to 0000 – many Chinese transmitters!
