Since observing 3 hours earlier, Syrtis Major had rotated into view. The break between Mare Cimmerium and Mare Tyrrhenum was still evident. I was surprised how far north Syrtis Major extended. There was still a dark feature flowing northwest from the SPC. I thought I detected some darkening in the midst of Elysium–although I can’t say what feature it might be. The thin dark collar around the SPC wasn’t as evident this time.
