Mars - 17th January 2010
      #3565719 - 01/17/10 07:39 AM Attachment (83 downloads)

Here's Mars drawn at 03:15UT with a Takahashi FS-128 at x238.

Seeing was poor - IV.

CM = 200'

Sadly it was the 'quiet side' but the large dark area to the bottom left of the drawing is strange. It does not match anything on the Martian maps but I saw it repeatedly !!!

The polar cap looks much smaller than 6 weeks ago when I first started observing Mars.

That's the area left of Elysium and going from Propontis to Cerberus. See my sketch (with Mars slightly earlier so the blotch more to the right) in another thread (in the solar system observation forum).

I too noticed it this apparition as something large and rather vague rather than two dark blotches with little in between, as I've sometimes seen it.

It's still strange that you didn't manage to catch the somewhat smaller Hyblaeus extension at the other side of Eysium, though, as it's smaller but much more contrasted against the central plains.

dweller25,

Very nice sketch. That patch northeast of Mare Cimmerium down to the Propontis complex is a bit darker than the surroundings including Amazonis to the east.

Thanks for the comments.

Sixela - I don't know why but I have only ever glimpsed the Hyblaeus extension even when favorably placed ! I have noticed before that areas that I should be seeing in the middle of Mars I cannot find. Perhaps I am concentrating too much on the larger easier areas ?

Frank - thanks for the pointer.

Most of the albedo markings in the central plains are fairly low in contrast.

Very nice drawing of mars,seeing anything in the central plains during this unfavorable opposition is very good.

Dweller,

An excellent observation of Mars. You have recorded Mare Sirenum/Mare Cimmerium over the south (extended dark streak) and the Phlegra region over the center of the planet. You may eb able to detect more albedo features under good seeing conditions. Thank you for sharing it with us all.

Carlos
