SUPERNOVAE 2007N-2007U
     Eight apparent supernovae have been discovered on unfiltered
CCD frames and reported to the Central Bureau:  2007N, 2007O, 2007P,
and 2007T by W. Li (LOSS/KAIT; cf. IAUC 8798; 2007N and 2007O with
N. Lee, 2007P with D. Winslow, and 2007T with D. R. Madison), and
the rest by T. Puckett (0.35-m reflector at Ellijay, GA, except
0.40-m reflector at Portal, AZ, for 2007U; cf. IAUC 8798; 2007Q and
2007U with J. Newton, 2007R with P. Gray, and 2007S with R. Gorelli).

2.38, [19.0; 2007 Jan. 13.41, [18.1; 24.38, 17.9.  SN 2007P is
probably a young type-II supernova (spectroscopic details on CBET
822).  Additional magnitudes by Puckett for 2007Q in NGC 5888:
2005 Nov. 15, [19.0; 2007 Jan. 26.40, 18.1.  SN 2007Q is a type-II
supernova discovered near the time of explosion (spectroscopic
details on CBET 840).  Additional magnitudes for 2007R in UGC 4008:
2005 Dec. 25, [19.0 (Puckett); 2007 Jan. 27.12, 16.5 (T. Orff).
SN 2007R is a type-Ia supernova next maximum (details on CBET 826).
Additional magnitudes for 2007S in UGC 5378:  2005 Dec. 29, [19.0
(Puckett); 2007 Jan. 31.20, 16.6 (Orff).  SN 2007S is a young
type-Ia supernova (spectroscopic details on CBETs 829 and 839).
Additional approximate KAIT magnitudes for 2007T in NGC 5828:  2006
Aug. 14.20, [19.0; 2007 Feb. 4.50, 16.8.  SN 2007T is a type-II
supernova, discovered near the time of explosion (details on CBET
837).  Additional magnitudes for 2007U in ESO 552-65:  Jan. 11,
[19.0 (Puckett); Feb. 6.02, 17.5 (Orff).  SN 2007U is a type-II
supernova found some 10 days past explosion (spectroscopic details
on CBET 838).
