Martian Drawings on 27 August 2003
at 03:15~05:00 GMT by Jeffrey D BEISH.

  λ=249゚Ls,   (ω=025°~051°W,   φ=19°S),   δ=25.1",   ι=5°

03:15-03:30 GMT (ω=025°~029°W)   590-670x
  SPC clear. "Mountains of Mitchel" are seperated from main cap and now obvious on east side of cap. NPR hood seen. MH. BC = 1.
  Nearling closest approach in a few hours.

  Seeing = 7-8. Transparency 5, Altitude 37°

04:30-05:00 GMT (ω= 044°~051°W, ).   670-1175x
  SPC clear. NPR hood seen. MH. MC just west of SPC. BC = 1. "Mountains of Mitchel" obvious detached on east side of cap (SPC).
  At times of perfect seeing surface details are sharp and high in contrast. Using this 41-cm f/.6.9 Newtonian with only 12% obstruction accomplishes high contrast images even at nearly 1,200x magnifications when the seeing conditions permit. A light breeze helped.
  As Mars approaches the nearest I will ever see it again I will stay up to observe the event that should occur at 0820 UT. The sky is absolutely clear with a brilliant Milky Way above and transparency is as clear as I have ever seen it. Mars is too bright in the 41-cm aperture, so I will use a neutral density filter.

  Seeing = 7-8. Transparency 5, Altitude 37°.

41cm f /6.9 Newtonian
Wratten Filters: W23A, W25, W33, W57, W64, W38A, W47.

The Beish Observatory is located (81°19'34.7"W, 27°21'07.1"N) at Lake Placid, FL, USA.
