Abstract:
Classifications on the DDO system are given for the host galaxies of
177 supernovae (SNe) that have been discovered since 1997 during the
course of the Lick Observatory Supernova Search with the Katzman
Automatic Imaging Telescope. Whereas SNe Ia occur in all galaxy types,
it is found, at a high level of statistical confidence, that SNe Ib,
Ic, and II are strongly concentrated in late-type galaxies. However,
attention is drawn to a possible exception provided by SN 2001I. This
SN IIn occurred in the E2 galaxy UGC 2836, which was not expected to
harbor a massive young supernova progenitor.

Note (1): Remarks:
1: dusty
2: digital IIIaJ image not yet available
3: edge-on
4: possible merger
5: conflicting classifications
6: probable dwarf
7: too distant to classify
8: it would be of interest to obtain large-scale images of the host of
SN 2001I (IIn) to check if this object is indeed an elliptical galaxy
9: possibly intergalactic
Note (2): the position did not exist in the original table -- it was
taken from the SIMBAD database.
