Seeing was good. By 22:00 it was clear. Stayed clear until 03:00 when some clouds began pass over us. We had an issue with the NA2 guider that it refused to guide on obviously suitable stars. It would mistake background noise for stars, etc. Checked the gcam temp and it was warm, but even when reset to -25C the behavior continued. Did not PR it just yet, as it may have just been a bad field, but obs specs should keep their eye on this for the next few nights. We were open all night. ------- 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 -------------------------------------------------------------------------- 20:33 AGILE 326( -978) 20 66 16.3 18.1 18.1 18.0 16.8 BG40 0.91 23:37 dcamera 360( 869) 206 56 14.6 15.0 15.6 14.8 14.7 - 1.32 01:17 arctic 322( 1055) -2 52 14.3 14.4 14.9 14.3 14.3 SDSS_z 1.11 Note: the wind was coming from the azimuth listed.
