CorMASS (Cornell Massachusetts Slit Spectrograph) is a low-resolution (R~300) prism cross-dispersed NIR Spectrograph. It is used on the Palomar Observatory 60-inch telescope. CorMASS' 2-dimensional spectral format provides simultaneous coverage of the IJHK bands, from ~0.75 microns to 2.5 microns. A remotely operated flip mirror allows the use of a slit viewing mode for object placement on the 15 x 2 arcsec slit. The primary scientific use of CorMASS is for the rapid spectral classification of low-mass stellar and sub-stellar candidate objects as identified by 2MASS (Two-Micron All Sky Survey).

On August 22nd, 1999 CorMASS saw first light, on the 60 in. Telescope at the Palomar Observatory in California. We also observed from October (99), February, March, April, May, and June. We are currently reducing the data from the ~100 targets we investigated. Our next observing runs are in August, September, and November
