SUPERNOVA 2009do IN NGC 4537
     A report from the following observers based on a single night image
of 2009do had been received prior to the issuance of CBET 1778; it appears
that NGC 4537 = MCG +09-21-22.
     T. Puckett, Ellijay, GA, U.S.A.; R. Gagliano, Cottonwood, AZ, U.S.A.;
and J. Newton, Portal, AZ, U.S.A., report the independent discovery of
2009do at mag 16.8 on unfiltered CCD images (limiting mag 19.1) taken with a
0.40-m reflector at Portal on Apr. 23.27 UT in the course of the Puckett
Observatory Supernova Search.  The new object was confirmed at mag 16.8 on
images (limiting mag 19.2) taken by T. Orff on Apr. 24.21 with a 0.40-m
reflector at Portal.  They measure the position of SN 2009do as R.A. =
12h34m58s.32, Decl. = +50o51'04".0 (equinox 2000.0), which is 9".9 west and
0".5 south of the center of NGC 4537.  Nothing is visible at this position
on images taken by Puckett on 2009 Apr. 9 (limiting mag 18.8).
     J. Nicolas, Vallauris, France, reports that his CCD image taken on
Apr. 24.871 UT with a 0.28-m f/6.5 reflector yields red mag 17.1 and
position end figures 58s.35, 04".1.
