Supernova 1999et was a hard case. It turns out that there is a nice little mag 16 star just a little to the north of the nucleus of NGC 1643. Several of the images on this page show that as the SN. These images will have a "?" in the comments fields. The real SN was a type II, found a couple months after max, and is to the south east of the core. Many thanks to Arno van Werven who stuck with this SN when nobody else would.
