Seeing was initially good, but then the wind turned east, and seeing fell to fair at best. NM01 ended early to allow us to tear down and stow the NAIC. Adler used two instruments, with a changeover at 03:03. All programs had clear weather, and got their data. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 20:32 naic 315( 1253) 72 53 9.7 11.4 10.8 11.7 10.9 600 1.00 01:25 arctic 624( 831) 167 61 7.4 7.0 7.6 7.0 7.0 SDSS-r 0.99 03:24 dcamera 588( 637) -90 68 7.8 6.9 7.5 7.1 7.1 - 1.25 Note: the wind was coming from the azimuth listed.
