Numerous supernovae have been discovered on unfiltered CCD frames: 2007cd by K. Itagaki (cf. IAUC 8817; via S. Nakano); 2007ce by R. Quimby (cf. IAUC 8779); 2007cf and 2007ci by T. Puckett (cf. IAUC 8834; 2007cf with W. McDonald, 2007ci with T. Crowley); 2007ch by L. A. G. Monard (cf. IAUC 8814); 2007cj by T.-H. Liou, T.-w. Chen et al. (cf. IAUC 8834); 2007ck by T. Boles (cf. IAUC 8789); and the rest by W. Li via LOSS/KAIT (cf. IAUC 8829; 2007ca with R. Prasad; 2007cb, 2007cc, and 2007cg with P. Thrasher). Discovery observations: SN 2007 UT R.A. (2000.0) Decl. Mag.
