SUPERNOVAE 2006fo AND 2006le-2006lu
Further to IAUC 8766, seven apparent supernovae have been
reported from unfiltered CCD images: 2006le, 2006lf, 2006lg,
2006li, and 2006lu by R. R. Prasad, N. Joubert, M. Baek, and W. Li
(LOSS/KAIT); and 2006lh and 2006lt by the "Nearby Supernova Factory"
collaboration (details on CBETs 708 and 714).

Additional KAIT magnitudes for 2006le in UGC 3218: Oct. 19.44 UT,
[19.1; 25.45, 18.5; 27.51, 17.6. SN 2006le is a type-Ia supernova,
well before maximum light on Oct. 27 (details on CBET 702).
Additional KAIT magnitudes for 2006lf in UGC 3108: Oct. 19.43,
[19.3; 27.51, 17.6. SN 2006lf is a type-Ia supernova, around 1
week before maximum light on Oct. 28 (details on CBET 705).
Additional KAIT magnitudes for 2006lg in UGC 2243: Oct. 1.38,
[19.0; 26.36, 18.4; 28.34, 18.5. SN 2006lg is a type-II supernova
(details on CBET 707). A spectrogram obtained on Oct. 28 showed
2006lh to be a young type-II supernova (details on CBET 708).
Additional magnitudes for 2006li in UGC 3664: 1989 Oct. 28, [21.0
(Digitized Sky Survey red plate); 2003 Oct. 22.52, 19.8 (KAIT);
2006 Oct. 29.52, 19.4 (KAIT). A spectrogram obtained on Oct. 13
suggests that 2006lt was then already a late type-Ib supernova.
Additional magnitudes for 2006lu: May 4.12, [18.8 (KAIT); Nov.
1.35, r = 17.51 +/- 0.03 (W. Krzeminsky and C. Contreras, on behalf
of the Carnegie Supernova Project; Las Campanas Observatory 1-m
Swope telescope).
J. Frieman, on behalf of the Sloan Digital Sky Survey II
collaboration, has further reported ten additional faint supernovae
(2006lj-2006ls; magnitude range: g = 21.3-23.5); details are given
on CBET 713. Frieman's group has also noted that further analysis
of the spectrum of 2006fo (cf. IAUC 8750) shows it to be consistent
with a type-Ic supernova, with features similar to that of 1999ex
(details on CBET 643).
