FROM Makoto Adachi
-------------------------------------------------------------------------------------

I captured my first image of Mars for 2009. 
It’s still very early in the season, with Mars still 288 million
kilometres away, subtending a tiny diameter of a 4.9" on the sky.

Mars doesn’t reach opposition until late January, 2010 when it will be 14
arcseconds in diameter ? a lot smaller than it was at its closest in 2003,
when it grew to 25" in diameter.

No polar cap is visible, but the features of Syrtis Major and the Hellas
Basin can be seen.
