Integration Times:

RED (RG610 Red Filter, 610-1100nm: NO IR Rejection) 0.12s 1-2 images

GREEN (CFW8C, 531nm central; BWHM 86nm) 0.37-0.39s 5-9 images

BLUE (CFW8C, 450nm central, BWHM 116nm) 1.20s 5-7 images

Images bias, flat and dark corrected.

 

Seeing fair (5-7, Pickering). Transparency variable (0-5.0 m) with frequent fast cumulus clouds. Wind E 7-14 kts. No dew. Altitude = 51 degrees.

 

Minimal clouds. Only a small orographic over Arsia Mons. Thin AM limb arc. Light haze over Eridania, bright in green. Possible small dust cloud in Northern Electris near southern border of Atlantis I. Trivium-Cerberus remains weak. SPC rifts prominent: Ulyxix Fr., Rima Australis, Magna Dep. Thyles Mons bright near CM. Violet Clearing = 0. Olympus very dark in blue and green.
