Martian Images taken 28 May 2003 at 18:24~19:46 GMT by Yukio MORITA.

  λ=193゚Ls,   (ω=012°- 032°W,   φ=20°S),   δ=12.0",   ι=43°
  Seeing: 4-5 /10.

 The inside of the spc seems to show a rift in addition to the shadowy area. Margaritifer S and Aurorae S look dark, while their southern area adjacent to them is faint. Especially the area to the south of Margaritifer S is devastated to the extent of Argyre.
  Notable is that the white mist along the EB is not seen. The northern area of M Acidalium shows a compact white cloud.

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).
