This is data just keeps on giving
, so I overlaid the orbital paths of Phobos and Deimos over my image. Paths were obtained from Starry Night Pro Plus 8 with a SNP8 screen capture attached.
On 6th October 2020 as viewed from Brisbane, Phobos was at Western Elongation at 23:08 and so when I grabbed this particular sequence, Phobos was some 0 hours and 32 minutes before reaching Western Elongation.
I have also annotated an image listing the SER File capture times from FireCapture to show the positions of Phobos along its orbital path from 22:21:33 through 23:53:05.
The gaps in timing were mainly due to clouds obscuring Mars, plus an uncommanded BSOD and computer restart incident.
Cheers
