Hi Edgar - We are 9 hours and 3200 years behind Greenwich so sundown is 0715Z and up at 1234Z today - its slowing but we are gaining over 4 mins of extra sun time at the moment here at this lat.
 
Mutual full darkness (sort of, as it really doesn't get completely Astro dark) from 0830Z till around 1130Z for Both ZL and Eastern VK, with Perth becoming mutually dark from 0937Z
 
I think we had a path to ZL on 137kHz this time of year from W5 a few years back but its really pushing it, some would say tongue in cheek, that we are exercising this path at this time of year - Im sure its open to Japan but not a lot of listeners there at the moment and QRM/N is a pain looking at their wx
 
Thanks for looking - Ill be WSPR15  pre  KL7 dusk WSPR15 250W (up a bit) with nominal signaling carrier center 475.815ish kHz GPS ref's with U3
