We have started a project to observe a subset of the sample of M, L,
and T dwarfs observed in the IRAC GTO program (Patten et al.  2006)
with the Peters Automated Infrared Imaging Telescope (PAIRITEL).
PAIRITEL is based on the 2MASS instrument and telescope at the Whipple
Observatory which has been upgraded to operate autonomously in a
queue-based mode (Bloom et al.  2006).  The purpose of the
observations is to assist in the search for low mass companions by
obtaining deeper J, H, K photometry of the fields to better match the
depth of the IRAC images, and to be able to search for companions
using similar proper motions.  For a subset of the M, L, and T dwarfs,
we are obtaining repeated measurements to monitor for photometric
variations.  We will summarize the status and results of the project.
