Location of site: Killeen, TX (Lat 31 N, Elev 600 ft)

Sky darkness: 3.35 <Limiting magnitude> 
Telescope: Orion 6" Dob.

No split at 32x, at 48x and 72x, some signs of elongation. Barely split at 120x. I tried higher powers with the barlow but the seeing did not support that. Both members appeared blue to me. I did an PA estimate of 220d (published 228d)
