Last night there was a hole in the cloud cover and I was able to observe Mars for about 15min. Conditions were far from perfect in this opening, with heavy haze and moisture.

The most striking feature is the night time part that now covers 12% of the visible planet disk, which I made a bit too large in my sketch. I was able to observe faint albedo features both to the North and South, which recently seem to be a bit lighter than in previous observations. A large morning cloud was observed in the Tharsis region. There is a large cloud covering over the NPC, and the southern hood also appears very large. The overall color of the visible disk remains a yellow/orange.

Yes, very nice. Did you really make it with a 70mm refractor? :shocked:

Thanks for the compliments.

Yes, it was with my 70mm achromat. I would prefer using either my 5" Mak or 6" Planetary Dob. However, it's the rainy season here in the tropics. Windows for observing show up unexpectedly and usually are short lived, so no time to acclimate or even set up a larger scope - The Mak and Dobs are currently in my storage room and not really being used.

What does help immensely is gaining observing experience. This apparition I have observed Mars at every opportunity since September 2013 and made many sketches. I'm not sure that last apparition I would have been able to see quite as much detail with a small scope. Living in Florida also helps, when it's not raining.

Ed,

An excellent observation and report on Mars. There appears to be a dust storm over the Syrtis Major region. I hope to observe Mars as soon as our weather and schedule allows. Thank you for sharing it with us all.

Regards,
Carlos

Thank you for all the wonderful compliments.

I attached a sketch of Mars from 2011 which took considerably more time to do. Wow, what a difference.

Thanks again,
Ed D

Ed nice work. I enjoy your very distinct presentation - nicy developed and original.

It is a little amazing just how different the features can be from one apparition to another. The shifting sands can really obscure or accentuate details or reinvent the apparent shapes of them. Add the atmospheric effects and suspended dust and it can really be a wildcard every time it swings around - as you amply show!

I always enjoy your work Ed. That its through a 70mm is particularly engaging. Well done.

Pete

Your Mars observation made in 2011 is also excellent. Thank you for sharing it with us all.

Ed,

Very nice observation and sketch. From the amount of detailed you pulled out of the 9 arcsec disk it shows that you have been observing Mars a lot this apparition. :)

Just the opposite for me--so far I've only observed the Red Planet a couple of times early on and haven't made any sketches so far. Guess I'd better hurry up.

Thanks everyone for the compliments.

Ed, you're right. I started observing and sketching Mars in late September of 2013. I currently have 19 sketches for this apparition. For some reason it seemed easier to observe detail during the approach than now as Mars gets further away. I have learned a lot about the planet during the past months, as well as realize how much there is that I don't know.
