SUPERNOVA 2009W
     A. U. Sugden and J. J. Salzer, Indiana University, report that images
of 2009W (cf. CBETs 1683, 1689) were obtained in a series of exposures taken
with the WIYN 0.9-m telescope on Kitt Peak using R-band and narrow-band
H_alpha filters on Mar. 19.48 UT; the supernova's magnitude was measured to
be R = 18.8, and its position was measured to be R.A. = 16h23m45s.68, Decl. =
+11o44'08".9 (equinox 2000.0).  No source is visible at the location of 2009W
in Sloan Digital Sky Survey images of the field (limiting r' magnitude about
23).  SN 2009W was detected as an H_alpha source in their WIYN data, with an
equivalent width of about 18 nm.
