Spitzer observations have a minimum 14 s cadence in standard science observing, which includes 6 s of array conditioning time in which photons are not collected. In order to collect spectra more rapidly, and have continuous photon collection, we observed for half an hour around the impact using a special engineering mode, SRS. We describe SRS mode, the methods used to plan and reduce the SRS data, and preliminary results on continuum and line emission caused by the impact in the 5.2-8.7 micron spectral range. This material is based upon work supported by the National Aeronautics and Space Administration under Award No. NAS7-03001 to The California Institute of Technology and Cornell University, and contract NASW 00004 to the University of Maryland.
