SUPERNOVA 2006bp IN NGC 3953
     R. Quimby, University of Texas; and P. Brown, Pennsylvania
State University, report that a spectrum (range 420-890 nm) of SN
2006bp (cf. IAUC 8700), obtained on Mar. 11.11 UT with the 9.2-m
Hobby-Eberly Telescope (+ Marcario Low-Resolution Spectrograph) by J.
Caldwell and S. Rostopchin, shows that it is likely a young type-II
supernova.  The spectrum has a blue continuum and shows a narrow
absorption line at 592 nm, consistent with Na I in the NGC 3953 rest
frame, and a narrow emission line consistent with rest-frame H-alpha
(possibly superimposed from the host).  There is also a broad
absorption line around 627 nm, and a narrow but slightly broadened
emission line at 583 nm.  Quimby adds SN 2006bp was not detected in
unfiltered ROTSE-IIIb images taken on Apr. 9.15 (limiting mag about
16.9), but it was found at about 15.3 mag on images taken on Apr. 10.15.
