From: harvanek@apo.nmsu.edu Subject: 2.5-m Obslog 20010116 (MJD 51926) Date: Wed, 17 Jan 2001 05:58:41 -0700 (MST) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday January 16, 2001 (MJD 51926) OBSERVING TEAM: =============== Mike Harvanek (APO) Dan Long (APO) VISITORS: ========= None. THE PLAN: ========= Science. Imaging if possible; otherwise spectroscopy. SYNOPSIS FOR NIGHT: =================== Never opened due to weather. GENERAL COMMENTS (see Problems below for details): ================================================== Clouds, high humidity and snow prevented us from opening. The spectrographs were focused using goSpecFocus. There were no problems. A flat and an arc taken after focusing showed all flat and arc characteristics to be within their tolerances. Neon arc lamp # 2 (directly above counterweight 3) was replaced.
