Syrtis Major and Hellas Basin are just past the central meridian.
Mars 2018-10-29 01:34 UTC

CM1: 301.40°
CLat: -19.60°
Description
With Saturn becoming too low to photograph, I turned my attention to Mars, where the seeing was much better due to the higher elevation.

Notes:
Sinus Meridiani is emerging from the night side of Mars.
Syrtis Major and Hellas Basin are just past the central meridian.
The south polar cap is small.
