> SUPERNOVA 2001az IN UGC 10483
> T. Puckett and M. Peoples, Mountain Town, GA, report the
> discovery of an apparent supernova (mag 17.1) on an unfiltered CCD
> frame (limiting mag 19.2) taken with the Puckett Observatory 0.30-m
> automated supernova patrol telescope on Apr. 27.39 UT. SN 2001az
> is located at R.A. = 16h34m27s.71, Decl. = +76o01'46".8 (equinox
> 2000.0), which is 4".9 west and 0".3 north of the center of UGC
> 10483. The new object was also present on an unfiltered CCD frame
> taken on Apr. 28.16, but it does not appear on multiple unfiltered
> images taken by Puckett from 1999 Aug. to 2000 May, and it does not
> appear on Palomar Sky Survey images taken on 1994 June 2, 1992 Apr.
> 10 (limiting mag about 21.0), and 1955 May 20 (limiting mag about
> 19.7).

> SUPERNOVA 2001ba IN MCG -05-28-1
> R. Chassagne, Ste. Clotilde, Ile de Reunion, reports the
> discovery of an apparent supernova (mag about 15.9) on unfiltered
> CCD images taken with a 0.3-m telescope on Apr. 27.8 and 28.7 UT.
> SN 2001ba is located at R.A. = 11h38m01s.76, Decl. = -32o19'51".0
> (equinox 2000.0), which is 18".7 east and 21".8 south of the
> nucleus of MCG -05-28-1 (= ESO 439-G18). An image of the same
> field taken on Feb. 19.9 showed nothing at this position (limiting
> mag about 18).
> P. Nugent and L. Wang, Lawrence Berkeley National Laboratory,
> report: "A spectrum (range 400-800 nm) obtained on Apr. 30.17 UT
> at the Kitt Peak 2.1-m telescope (+ GCAM) shows that SN 2001ba is a
> type-Ia supernova near maximum light. Adopting the NASA/IPAC
> Extragalactic Database recession velocity of 8819 km/s for the host,
> we find that the minimum of the Si II feature is at a velocity of
> 10 900 km/s."

> SUPERNOVA 2001bb IN IC 4319
> M. Schwartz, Cottage Grove, OR; and W. D. Li, University of
> California at Berkeley, on behalf of LOTOSS (cf. IAUC 7514), report
> the discovery of an apparent supernova on unfiltered images taken
> with the 0.5-m Tenagra III automated telescope on Apr. 29.3 (mag
> about 16.5) and 30.2 UT (mag about 16.3). SN 2001bb is located at
> R.A. = 13h43m25s.31, Decl. = -29o48'13".1 (equinox 2000.0), which
> is about 16".8 west and 1".4 south of the nucleus of IC 4319. An
> image taken by the Katzman Automatic Imaging Telescope on Apr. 15.3
> showed nothing at this position (limiting mag about 18.5).
