Monthly report for November 2000 by Christian A. Hummel: The paper on NPOI observations of Omicron Leonis was accepted for publication by the Astronomical Journal. Hummel developed an HTML lab script on NPOI data reduction for use in the lab sessions at next year's Michelson Summer School in Flagstaff. This script will serve as a container for any lab instructions to be added during the next few months. Hummel provided a new FITS output for the NPOI data files which implements multi-IF and multi-source formats. These files can be directly read with AIPS for imaging purposes and should be more usable with bandwidth synthesis tasks.
