Notes from 4pm meeting

  • For first-half observers, be sure to fill in the CTIO night report and leave it open for the second-half observers.
  • For either first- or second-half observers: try not to "zap" any windows on the observer2 console that would be useful for the program running in the other half.
  • Sultan-of-seeing predicts poor seeing for tonight.
