It was closed at 19:15 MDT to take cals, and reopened at 20:00 MDT. The observers were Joni Johnson and Tom Harrison for NM08 and Gyula Szokoly for JH03. No problems to report, except seeing has been below average for the past three nights. OBSERVER COMMENTS Joni (NM08) - "Good, dust-free, less windy conditions. Seeing was okay. All of our observational goals for this evening were accomplished, including a (personal) Target of Opportunity, CI Cam, a symbiotic star that recently was a transient x-ray burst source, unheard of in a symbiotic star."
