Hi All,

Here are some Mars images from 17 August. Taken with 16-in Newtonian. In addition I have attached an image taken by Sheldon Faworski with my 10-inch Mewlon, Paramount ME, and ToUCam.

Note tiny orographic cloud over Arsia Mons and bright aureole in the Olympus Mons region.

Best,

Don

Hi Again,

Sorry, I sent the wrong image just now. I have been spending too much time staring at the computer doing these %%^%###@ images! Here is the correct one.

Hi All,

I have attached some Mars images from 19 August (this time with proper color correction!). In addition there are some images taken by Sheldon Faworski with my Mewlon and a ToUCam (18 August & 19 August). The 17 August images have been resubmitted, since the times and CMs were in error.

Best,

Don

Hi All,

I have attached some Mars images from 13 August and 17 August. These had been sent before, but the color balance on my monitor had changed, most likely due to a power surge, making the images pink. A pretty color, but not for Mars! Sorry for the trouble.

Best,

Don

MARS IMAGES 22 August, 2003

D.C. Parker, Coral Gables, FL. 16-in (41cm) Newtonian

ST9XE CCD Camera Eyepiece Projection @ f/58.6

Integration Times:

RED (RG610 Red Filter, 610-1100nm: NO IR Rejection) 0.12-.13s 1-3 images

GREEN (CFW8C, 531nm central; BWHM 86nm) 0.33s 8-11 images

BLUE (CFW8C, 450nm central, BWHM 116nm) 1.00s 7-11 images

Images bias, flat and dark corrected.

Seeing fair (6-7 Pickering). Transparency 4-4.5 m with thin haze and fast cumulus clouds. Wind ESE 3-10 kts. Altitude =41-48 degrees. No dew.

Violet clearing has increased, = 2+. Thyles Mons breaking away from AM side of the SPC. NP hood not as conspicuous as during last few weeks. No dust. Some limb hazes, but Martian atmosphere otherwise clear. Olympus Mons region bright near NW limb -- possible ice fogs at its base? The Tithonius region, north of Solis Lacus has become dark and broad, such like it did in 1926-1929.
