@. . . . . . Well, i finally got around to shooting my first Mars
images* this apparition (seeing at the low altitude was finally
consistently good enough!) I attach the results. Mars was just 10.5degs above
the Horizon when these were obtained - a wonder anything at all is possible.

Time:
Mars
CML: 323degs
Ls:

Diameter:

Altitude
of Mars: 10 - 10.5degs.
Comments: Initially fair seeing allowed a reasonable view, but
this soon deteriorated, with "fast" seeing developing, and
increasing. Hellas appeared bright, with a yellowish tint, noticeably different
from the ruddy orange desert regions of Moab etc. The eastern part of Syrtis
Major was obscured by dust. I suspected the dust extended as far north as
Boreosyrtis. Cloud/haze were seen around the NPC area, again toward Cydonia as
visible last night. Also faint clouds/haze over
