Telescope and AGw Commissioning at LFBG with IRTC - 15-16 April 2009 MST

Observers: D.Thompson, MPedani (@LBT)
Telescope Operator: W.Wack
Telescope Support: JLittle
Instrument Support: JMorris
SW Support:


  • Three (so far!) complete failures of the chillers. LUCIFER cuts off CCC power due to over-temperatures. See
  • Lost entire night to high winds (up to 88 mph this afternoon) and humidity.
  • John most likely found the source of the high residuals - truncation on conversion to radians somewhere in the path between IRC and PCS. Once fixed, we can test it closed dome.


We have had a 10C drop in temperature since this afternoon. M1 is -0.8C and outside is -9.6C.
