SUPERNOVAE 2003iy AND 2003iz

The discoveries of two apparent supernovae have been reported
from unfiltered CCD images:  2003iy in NGC 6143 by K. Itagaki
(Teppo-cho, Yamagata, Japan, 0.6-m reflector; via S. Nakano, Sumoto,
Japan) and 2003iz in UGC 638 by B. Beutler and W. Li (LOSS/KAIT; cf.
IAUC 8229).
