SUPERNOVAE 2003gn, 2003go, 2003gp, 2003gq

Four additional apparent supernovae have been found on
unfiltered CCD images, each by LOTOSS/KAIT (via J. Graham, D. Weisz,
and W. Li; cf. IAUC 8162), with SN 2003gq reported initially by T.
Puckett and A. Langoussis (cf. IAUC 8154; Puckett's data for SN
2003gq tabulated below).  Li provides position end figures 20s.74,
57".6 for SN 2003gq.
