SUPERNOVA 2009F IN NGC 1725
     H. Marion, University of Texas; P. Garnavich, University of Notre Dame;
C. L. Gerardy, Florida State University; S. Gooding, Texas A&M University,
J. Vinko, University of Texas; and E. Hsiao, University of Victoria, write
that they obtained a spectrogram (range 0.7-2.4 microns) of 2009F (cf. CBETs
1650, 1654) on Jan. 7.28 UT with the Infrared Telescope Facility (+ SpeX in
low-dispersion mode).  The spectrum displays features from Ca II, Mg II, and
O I lines and is consistent with a type-Ia supernova observed near maximum
light.  The infrared spectrum of SN 2009F is similar to spectra from SNE
2002hw (obtained one day before maximum) and 2000dm (obtained one day after
maximum).
