Parker Solar Probe (Delta IV main rocket engine?) venting over Ma Ma Creek, QLD. This was a spectacular sight. The cloud was bright orange as it rose over the range as the sun went down. Unfortunately only captured that part in my head.
Imaged 18:26 to 19:06 local time (0826 - 0906GMT), exposures 1 to 15 seconds, ISO 800 to 3200, EOS7D @ 200mm.
