    v199 v200  
    183183  *  Start VIRUS script {{{vsky.sh }}} when GC2 flux is 6.6k
    184184
     185* Some time in early October (2018), take HPF twilight spectra.
     186    * open the PFIP shutter, make sure ACAM and FCU head are retracted
     187    * 2-3min after sunset, run {{{hpframp twilight 28 1}}}
     188    * this should produce nice twilight flats for HPF, but may eliminate your chance of getting LRS2 sky flats that night
     189
    185190* Take twilight spectra (start GC2 and check flux level - ~22k LRS2 and 4.7k virus for B filter and exp 0.1s);  NOTE:  30k for LRS2 and 5.5k for VIRUS seemed to work better in the summer.  If you end up using GC1 on filter B then you should use ~36k for LRS2 and ~6.9k for VIRUS.
    186191   * First any imaging cameras
