Seeing: 9 <1-10 Seeing Scale (10 best)>
Location of site: Lolog, Argentina
71º18´W, 40º02´S 
Site classification: Rural
Sky darkness: 6.0 <Limiting magnitude>
Telescope: Refractor Vixen 60S f/7
on equatorial mount & SS2K 
Eyepieces: ULTIMA 30 mm, Powermate 2.5x
Magnification: 40x
Very rich field shown at this power (40x). There´s a few catalogued doubles in the field making easy to locate our star. The components AB were split clearly at the current power but it is a faint double. Furthermore, A looks oranges and faint, and B is so dim and difficult to determinate the color.

Seeing: 5 <1-10 Seeing Scale (10 best)>
Transparency: 4 <1-10 Seeing Scale (10 best)>
Location of site: Seven HIlls NSW, Australia
Site classification: Suburban
Sky darkness: ---
Telescope: 8 inch Celetron Starhopper
Magnification: 48x
Description No colours noted Easy split at low power . No colour noted in either star. Located just south of CanM 17.

Ambience: After too long a break punctuated by the sword rattling of nations. The near incineration of a nation, and the happier arrival of Santa Claus. It felt good to get out under the celestial sphere. My telesecope was bordering on needing therapy to convince the instrument it wasn’t a piece of houshold furniture.
 
The night was filled with the sounds of insects calling to mates. The air was heavy, and a sent of smoke filled the air – evidence of the vast back burning operations to my west in the mountains. Overhead, Orion, The big dog and the celstial voyager (Carina) reared into the sky. M 42 appeared shrunken indicating a poor night of transparency. While the Trapezium agreed to yeild 5 of it’s members.

A quick inspection of Rigel and Espilon Cma further indicated the night would be not yeild any close doubles So without further ado. Here are the observations for 11/01/02. A paulty collection of fleas of the dogs back, but still enough to remind me why I look up.

A wide pair, mag 8 & 9. Estimated PA about 40d. A third, unrelated star lies to the
SE,  making a long, narrow isoseles trinagle. Both members of this system are
white.
