2007IAUC.8798A...1J Circular No. 8798 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION 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). SN 2007 UT R.A. (2000.0) Decl. Mag.

The tabulated offset for 2007G is with respect to the center of the eastern component in the double-nucleus galaxy UGC 68 (PGC 167). W. Li provides position end figures 09s.78, 11".2 for 2007G (and offset 0".5 east, 1".5 south of the western component of the nucleus of UGC 68). Additional magnitudes for 2007H: 2006 Dec. 19.39, [19.0; 2007 Jan. 14.37, 17.9. Additional magnitudes for 2007I: 2006 Dec. 7.46, [19.2; 2007 Jan. 15.49, 17.6.
