2003 06 28 Mo Note
Martian Images taken 28 June 2003 at 17:12 ~ 19:40 GMT by Yukio MORITA.

  λ=211゚Ls,   (ω=057~ 092°W,   φ=21°S),   δ=16.2",   ι=38°
  Seeing: 3 /10.

Note:
  Often interrupted by cloud floats (now midst the rainy season here), and so not every 40 minute observations: The Aurea Chersonesus complex is easily checked because the angular diameter has increased. The Phasis-Phoenicis L hook is also quite evident. The area between Phasis and Solis L is rather bright (as well as Ophir). Notable is a vast expansion of the water vapour mist over the surface and the morning side and even the evening side are thickly covered (the southern high latitude morning limb is the thickest).

Instrument:
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).

Image data are
    23 R + IR Rejection images each with 0.2 secs
