SUPERNOVA 2010lm
     Further to CBET 2603, and on behalf of the "Palomar Transient Factory"
group (http://www.astro.caltech.edu/ptf/), J. Parrent, D. A. Howell, Richard
Ellis, Avishay Gal-Yam, and P. E. Nugent write that a CCD spectrum (range
350-950 nm), taken on the Gemini South telescope on Dec. 24 UT, reveals that
2010lm is a type-Ia supernova before maximum light, near -7 days.  They
determined z = 0.054 from the host-galaxy's H-alpha and O II 500.7-nm and
from fits to the supernova features.
