Seeing: 8 <1-10 Seeing Scale (10 best)>. 
Transparency: 
Location of site: Texas, USA
Site classification: suburban
Conditions: No moon
Sky darkness: 4 <Limiting magnitude> 
Telescope: C8
Eyepieces: 25mm, 17mm, and 
10mm 
Magnification: 		 Another pair of saphires, not quite as bright as psi. Appears at the corner of a somewhat lop-sided square, with some other stars scattered around in the square. Estimated PA about 240°.

Ambience: The weather is getting to be what passes for cool in these parts, although I was quite comfortable wearing shorts and a T-shirt. At one time I thought I saw a satellite in the FOV, but a closer look revealed the red and green navigation lights of some jet liner passing 
overhead. At another time, one of the local puddle-jumpers passed overhead while turning final for the airport about a mile away.
