Abstract (from CDS):
The "Nearby Supernova Factory" collaboration (E. Pecontal and G. Rigaudier, Centre de Recherche Astronomique de Lyon; P. Antilogus, S. Gilles, R. Pain, and R. Pereira, Laboratoire de Physique Nucleaire et de Haute Energies de Paris; C. Buton, Y. Copin, E. Gangler, and G. Smadja, Institut de Physique Nucleaire de Lyon; G. Aldering, C. Aragon, S. Bailey, S. Bongard, M. J. Childress, S. Koshy, S. Loken, P. Nugent, S. Perlmutter, K. Runge, R. Scalzo, R. C. Thomas, and B. A. Weaver, Lawrence Berkeley National Laboratory, Berkeley; R. Kessler, Kavli Institute for Cosmological Physics, Chicago; and C. Baltay, A. Bauer, D. Herrera, and D. Rabinowitz, Yale University) reports the discovery of a supernova (mag approximately 19.4, calibrated to R) in NEAT images (cf. CBET 263) obtained on Oct. 24.2 UT using the QUEST II camera on the Palomar Oschin 1.2-m Schmidt telescope as a part of the Palomar- QUEST Consortium. The new object is located at R.A. = 23h26m51s.60, Decl. = +9d19'57".6 (equinox 2000.0). Nothing was visible at this location on an image obtained on Oct. 9. A spectrum (range 320-1000 nm) of 2006lh, obtained on Oct. 28.3 with the Supernova Integral Field Spectrograph on the University of Hawaii 2.2-m telescope, reveals that it is a young type-II supernova at a redshift of z = 0.032, judging from the location of the peak of its H-alpha P-Cyg emission. P-Cyg H-beta is also detected. A maximum ejection velocity of 8600 km/s is measured from the blue wing of the H-alpha absorption.
