Martian Images taken on 21 April 2003 at 19:21~20:17 GMT by Yukio MORITA.

  λ=172゚Ls,   (ω=024°W - 036°W,   φ=15°S),   δ=8.7",   ι=43°
  Seeing: 3/10.

  The south polar canopy is bright in R as well as in B, and hencen though the haze is still covering, the south polar cap must show up now definitely beneath the canopy. The canopy looks partly down to the area of Argyre.
  Aurorae S looks dark. Niliacus L is also dark on the NH, and sends a faint Nilokeras.

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).
