Martian Images taken on 26 April 2003 at 19:04~20:30 GMT by Yukio MORITA.

  λ=175゚Ls,   (ω=331°W - 351°W,   φ=16°S),   δ=9.1",   ι=43°
  Seeing: 3-4/10.

The spc is now definite though still slightly misty at the polar region.
The images at the ω=345°W series are mildly processed and show a morning mist at Chryse. The circumpolar band is still dark, but the usual markings such as S Sabaeus are less dense than usual. M Acidalium finally came out.

Use is made of an f /7.7 Newtonian extended to f /50 having a 25 cm speculum equipped with an ST-5C (at -5゚C).
