MDM Observatory 1.3m Telescope Observer's Report for 2007 Jun 14 Observer(s): Vestergaard Institution(s): Arizona Instrument: ccds Worked for 8.5 hours (all night) Conditions were Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Beg: Seeing 2.0 arcsec, Clear, Winds Light & Variable Mid: Seeing 2.0 arcsec, Clear, Winds Light & Variable End: Seeing 1.5 arcsec, Clear, Winds Light & Variable Observing Summary: A few light cirrus in far horizon at sunset, so start might not have been 100% photometric - but as clouds were dissipating toward sunset I presume it became photometric soon afterwards Light variable winds. Nice night, although I was mostly chasing our objects at high airmass so seeing was about 2 arcsec for most of night. At end (at zenith) it seems a typical seeing was about 1.5 . PS: The LN2 was replaced this pm. At 5pm I found a large hole in fill-tube near the metal spout. As I couldn't tell if any of the LN2 was going into dewar I took the liberty of shortening the fill-tube to avoid this hole. ------------------------------ Submitted on 2007 Jun 15 [4:58:48]
