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.

That's some good detail Ivano in those conditions. Conversely I was getting indications of poor seeing (my latest post thread here) and got superb!

I suspect the S. Maj. was getting shrouded in (blue?) cloud when you were looking for it near the terminator.

Hi David,

Yes that's what I thought. I was looking for a contemporary observation but couldn't find it on the web.

I've been very impressed by your recent observations of Mars by the way; I guess your eyesight is at least as good as your telescope, now I spend most of my time waiting for floaters and other *BEEP* I have in my eyes to get out of the way.

Ivano, good to see you observing Mars. You captured some fine detail, and it looks to be a great observing season with Mars. Can't wait to join you sketching the planet.

Ivano,

Nice work--you pulled some pretty accurate detail out of some poor seeing conditions. I guess we can look forward to more clouds as Mars progresses further into northern spring.
