These observations were obtained with the HIRES instrument on Keck 1. We observed brightening of both the dust and gas, but at different rates. We report the behavior of OH, NH, CN, C$_{3}$, CH, NH$_{2}$ and C$_{2}$ gas. From our observations, we determined a CN outflow velocity of at least 0.51 km sec$^{-1}$. The dust color did not change substantially. To date, we see no new species in our spectra, nor do we see any evidence ","authors_text":"Anita L. Cochran, Karen J. Meech, Micah Glaz, William M.
