The higher the latitude the more drawn out the sunset. In Caernarfon, Western Australia which is on the Tropic of Capricorn, I was there near the equinox in 1969. I clearly remember it was as light as midday at 17:50, going dark at 17:55 and was dark at 18:05 with a dull red glow to the west and pitch black at 18:10. Peter
