  We have begun a program to search for supernovae and other transients in the
fields of galaxy clusters with the 2.3m Bok Telescope on Kitt Peak. We present
our automated photometric methods for data reduction, efficiency
characterization, and initial spectroscopy. With this program, we aim to
ultimately identify $\sim$25-35 cluster SN Ia ($\sim$10 of which will be
intracluster, hostless events) and constrain the SN Ia rate associated with
old, passive stellar populations. With these measurements we will constrain the
relative contribution of hostless and hosted SN Ia to the metal enrichment of
the intracluster medium. In the current work, we have identified a central
excess of transient events within $1.25 r_{200}$ in our cluster fields after
statistically subtracting out the 'background' transient rate taken from an
off-cluster CCD chip. Based on the published rate of SN Ia for cluster
populations we estimate that $\sim$20 percent of the excess cluster transients
are due to cluster SN Ia, a comparable fraction to core collapse (CC)
supernovae and the remaining are likely to be active galactic nuclei.
Interestingly, we have identified three intracluster SN candidates, all of
which lay beyond $R>r_{200}$. These events, if truly associated with the
cluster, indicate a large deficit of intracluster (IC) SN at smaller radii, and
may be associated with the IC stars of infalling groups or indicate that the
intracluster light (ICL) in the cluster outskirts is actively forming stars
which contribute CC SN or prompt SN Ia.
