Hi Chris,
I've looked at the newest image and now I think I can see what is may
be light from the SN. The host is clearly red since it is strong
compared to the host relative to the I-band SN/host ratio. Thus, it is
likely that at least half the light is host light, putting the SN at
J ~ 23.7 for SN+host of J ~ 23. Under this hypothesis, the SN S/N would
be about 10, meaning that more integration (e.g., the full 10 hours) is
needed.
He haven't yet gotten the HST images for S02-032, so have nothing
more to add to the discussions on that front.
