We present HST and ground observations of SN 2008A. The early-time
spectra and light curves show that SN 2008A is very similar to SN
2002cx and SN 2005hk, making it part of the SN 2002cx-like subclass of
peculiar type Ia supernovae (Jha et al. 2006). Late-time spectroscopy
of members of this class, including SN 2008A, provide evidence for
significant amounts of high density, low velocity material. Even
though this is a very uniform class of Type Ia supernovae, from HST
imaging we find that SN 2008A is declining faster at late times than
SN 2005hk. We will obtain a second epoch of HST imaging in late August
2009 to follow SN 2008A and constrain models for this subclass,
including the possibility of a pure deflagration explosion.
