@. . . . . . Here is another Mars
observation. A period of good seeing lasting about an hour gave the most
detailed views of the Planet so far. This is certainly one of the best views i
have had of Mars at less than 7" diameter. I also obtained images which will
follow sometime soon.

Comments: A period of fair-good
seeing occurred during this visual observation and allowed significant detail to
be seen (the best view so far this apparition.) Firstly Hellas was very
distinct, and appeared large unfiltered. It was also prominent in the W#21
filter. Syrtis Major/Deltoton Sinus appeared very prominent and dark. Mare
Serpentis also dark. Sinus Sabeaus/Meridiani prominent. Utopia observed, though
appeared fainter than other surface markings. CCD images incicated at a distinct
cloud/haze over Aeria/Moab. NPC rather indistinct (but a white spot was still observed) as
the North Pole begins to tilt away from Earth.
