Dear Masatsugu,

Many thanks for finding and telling me about the errors in my images. I have corrected them. For the De, I will start using a program that Jeff recommended called MAPOS. It is more accurate, according to Jeff, although a bit cumbersome to use. Sorry for the mistakes, but I appreciate your diligence in checking the data.

Hope all is well with you. I am getting tired of Mars!

Best,

Hi All,

Masatsugu Minami has pointed out errors in the Ls and Cms on my 14 October images. I have corrected these and enclosed the revised edition. Sorry for the mistakes. The Curse of the Red Planet continues!

Hi All,

I have attached some Mars images from 23 October.

Best,

 

Don PARKER's Images on 23 October 2003 at 00:32~ 01:24 GMT

  λ=285Ls,   (ω=188W, 197W,   φ=23S),   δ=16.5",   ι=36

Seeing poor, "slow" (3-4 Pickering). Transparency = 4.5m.
Wind W 0-7 kts. Altitude = 48-51. No dew.

Note:
Brilliant small cloud on PM limb near Arsia Mons. Bright localized cloud in northern Zephyria-Amazonis SE of the still weak Trivium-Cerberus. Violet Clearing = 0.

PARKER uses a 41 cm Newtonian working at f /59 with an eyepiece projection together with an SBIG ST9XE ccd camera, equipped with a CFW-8C filter wheel and RGB interference filters

Integration times:
  Red      (610 -1100nm) :   0.14s   2 images   (RG610, NO IR ejection)
  Green   (488 - 574nm) :    0.60s   4-5 images
  Blue      (392 - 508nm) :   2.50s   3-6 images
Images bias, flat and dark corrected.
