Star: South 390 Date & Time: 2 Nov 2003 9:30pm to midnight Seeing: 2-3 <1-10 Seeing Scale (10 best)>. Transparency: poor Location of site: Silverdale WA, USA 47N 123W Site classification: suburb-rural Conditions: temp 30-35F, dry Sky darkness: 4.0 due moon <Limiting magnitude> Telescope: Celestron C8 Eyepieces: DX-8263SL video camera at prime focus Magnification: app. 333x				Missed this on the first try and landed about a degree south preceding and found a nice triple, BU 234 all in the 8-9th mag range. Finally got to the correct star and found a pair of equal white stars, nice and bright. Measurement; 6.67 sec at 216.3 deg PA.

Star: South 390 Date & Time: November, 19th 2003 10.30-12 mid-night local; UT +10 Seeing: 7 <1-10 Seeing Scale (10 best)>. Transparency: 8 <1-10 Scale (10 best)> Location of site: Terara, New South Wales Australia, Long.150.38 ; Lat -34.52. Site classification: suburb-rural Conditions: Temp 16° No Moon Sky darkness: <Limiting magnitude> Telescope: 8" F9 Newtonian. Eyepieces Eyepieces: 16mm and 12mm Ortho Magnification: Harshaw Scale: 2 <1-5, 1 best>				Mag. 7.0/7.1; Sep. 6.4" In the finderscope this beautiful object is a binocular double and part of a triangle of mag. 7 stars southwest of the line connecting Beta and Eta Ceti. This pair separate nicely at low power with the fainter star Bluish while a bright star sits west in the field.

Star: South 390 Date & Time: Saturday November 29, 2003 Seeing: 7 <1-10 Seeing Scale (10 best)>. Transparency: --- <1-10 Scale (10 best)> Location of site: Texas, USA Site classification: suburban Conditions: Cool, 44°F, 7°C. Crescent moon Sky darkness: 4 <Limiting magnitude> Telescope: C8 Eyepieces: 25mm, 17mm, and 10mm eyepieces Magnification:				Easily split at low power, yellow in color. I estimated the PA at about 225°. This points almost directly at a third star, quite some distance away and almost certainly not related. Near the edge of the low power FOV was a third star, together the 3 form a very flattened scalene triangle.
