The website I usually consult did forecast seeing I for the morning of Sept. 18, so I drove to Bethany Observing Station (CT). It turned out to be around IV... Pretty weird, as those forecasts are usually reliable.

Anyway, I was there and here's the 1st Mars of the season, with intensity estimates (BAA scale). Not sure about the white clouds on the E limb, but Syrtis Maior should have been right there and I could not see it. I could not find any observations made at the same time. Uncertainties are due to bad seeing, not the small size of the planet; I'm always impressed at how much this planet can show on such a tiny disk.

Overall, the planet looked very much like in Paul Abel's sketch of the previous day but more cloudy.

You must have had a great session and viewing conditions! Your sketch is well detailed and it is reminescent of what I remember from my last sight of Mars, about a year ago at least, I guess. The features do seem to lie and blend the way you've drawn it. Good sketch.
