the discovery of 10 supernovae found with the Advanced Camera for Surveys
(ACS) on the Hubble Space Telescope during the period 02-04 April 2004.
Deep F850LP (z'-band) and F775W (i'-band) imaging taken of the GOODS HDF-N
field were compared with the one year old GOODS survey data.  The search
limiting Vega magnitudes were z'=26.2 and i'=26.5.  B. Mobasher provided
host galaxy photometric redshifts and host galaxy types based on results
from the GOODS survey.  We report only those events with magnitudes and
colors which are consistent with the photometric redshifts.  Supernova are
sorted by right ascension.

Photometric redshifts are generally known to better than +/-0.3 (95%
confidence).  "?" or "??" denote redshifts or host types which are less
well constrained.
