It was the first time I looked for a second time the same region of Mars. Compared with an observation of the 1st of january Hellas was very difficult to see. One month ago it was very bright.
This time I also noticed almost no limb haze. There was only I brighter region at the northwest of Mars (or was it Mare Acidalium rolling in?).
Mare Serpentis and Sinus Sabeus looked like a half-ring on the southwest. Beautiful sight!
Another strange thing is the position of Syrtis Major. I see it in the eyepiece far south (it doesn't cross the "middle" of Mars). In simmulations of Mars it comes far more north.
All comments are wellcome!
