Observers: S. Chung, J. Gerke, D. Berg Telescope Operator: D. Gonzalez-Huerta Support Astronomer: Dave Thompson Summary: Only have LBC targets left, but seeing conditions were poor the entire evening. OBs: OSU_MONITOR_N6946,OSU_MONITOR_N672, ND_oldsn/sn09ig_BR, ND_oldsn/sn09ig_VI, OSU_MONITOR_N2403,OSU_MONITOR_N3077,OSU_MONITOR_M81,and OSU_MONITOR_N2903. Weather: Overcast on and off through night, so were closed twice until conditions improved. Light to moderate sirus was present the entire night. Seeing was highly variable.
