SUPERNOVAE 2006cl, 2006cm, 2006cn, 2006co, 2006cp, 2006cq, 2006cr
Seven new apparent supernovae found on unfiltered CCD frames
have been reported: 2006cl and 2006cn by the 'Nearby Supernova
Factory' collaboration (cf. CBETs 520, 522); 2006cm and 2006cq by T.
Puckett (with A. Langoussis for 2006cm, and with J. Newton and E.
Briggs for 2006cq); 2006co by C. Colesanti, C. Jacques, E. Pimentel,
and T. Napoleao (cf. IAUC 8658); 2006cp by H. Khandrika and W. Li
(LOSS/KAIT; cf. IAUC 8710); and 2006cr by T. Boles (cf. IAUC 8699).

Spectra show that 2006cl, 2006cn, and 2006co are type-II supernovae
(details on CBETs 520, 522, and 529). Additional magnitudes for
2006cm in UGC 11723: 2005 Nov. 25, [19.3; 2006 May 25.37 UT, 16.4.
A spectrum of 2006cm taken on May 29.47 showed it to be a reddened
type-Ia supernova near maximum (details on CBET 526). Additional
magnitudes for 2006co in ESO 323-G25: May 4.06, [18.5; 27.89, 15.9.
Nothing was visible at the location of 2006co on a red Digitized
Sky Survey (DSS) image from 1994. Additional magnitudes for 2006cp
in UGC 7357: May 16.24, [19.0; 29.20, 17.8. A spectrum of 2006cp
taken on May 30.26 showed it to be a type-Ia supernova around 1
week before maximum (details on CBET 528). Additional magnitudes
for 2006cq in IC 4239: Jan. 20, [19.5 (Puckett); May 30.22, 17.3
(A. Sehgal, 0.50-m reflector, Osoyoos, BC). A spectrum of 2006cq
obtained on May 31 showed it to be a type-Ia supernova close to
maximum brightness (details on CBET 529). Additional magnitudes
for 2006cr in UGC 8205: 1995 Apr. 23, [21.0 (DSS blue); 1997 June
25, [20.5 (DSS red); 2006 Apr. 5 and May 15, [19.5 (Boles). A
spectrum of 2006cr taken on June 1 shows it to be a type-II
supernova about 1 week past explosion (details on CBET 531).
