MAO/AERI/M1 - White light failure

No data during this period.  

White light had failed.  Instrument repairs onsite by Jonathan Gero were successfully 
completed and instrument was back operational on December 1.  End of deployment calibration 
verification tests passed, instrument was packed and is ready to be installed at the next 
site.
