SUPERNOVAE 2007G, 2007H, 2007I, 2007J, 2007K, 2007L, 2007M
     Seven apparent supernovae have been discovered on unfiltered
CCD frames:  2007G by C. C. Jin, Y. Cao, F.-Y. Bian, Y.-Q. Lou, X.
F. Wang, Y. Wu, and Y. Yang (THCA Supernova Survey/TNT; cf. IAUC
8648); 2007J independently by J. Newton and T. Puckett (cf. IAUC
8794; 0.40-m reflector at Portal, AZ) and by N. Lee and W. Li
(LOSS/KAIT; cf. IAUC 8794; source of tabulated data below); and the
rest via LOSS (N. Joubert, N. Lee, D. R. Madison, R. Mostardi, and
W. Li).
