SUPERNOVA 2004eu IN MCG +07-5-39
     T. Boles, Coddenham, England, reports the discovery of an
apparent supernova (mag 17.3) on unfiltered CCD images taken on
Oct. 6.203 and 6.890 UT with a 0.35-m reflector.  The new object is
located at R.A. = 2h20m34s.86, Decl. = +41o34'18".5, which is
approximately 2".1 west and 7".9 south of the center of MCG
+07-5-39.  SN 2004eu is not present on Boles' images from 2004
Sept. 15 and 2003 Dec. 28 (limiting mag 19.5) or on Digitized Sky
Survey red (1987 Oct. 18, limiting mag 21.0) and blue plates (1989
Sept. 6, limiting mag 21.5).


SUPERNOVA 2004ev IN ESO 459-G13
     Further to IAUC 8405, T. Puckett and J. Newton report the
discovery of an apparent supernova (mag 18.1) on an unfiltered CCD
frame taken with the 0.35-m automated supernova patrol telescope on
Oct. 6.03 UT, confirmed by Puckett on a frame taken on Oct. 7.03
(at mag 18.1) with a 0.60-m reflector.  The new object is located
at R.A. = 19h20m31s.78, Decl. = -28o55'14".9 (equinox 2000.0),
which is 21".4 east and 3".8 south of the center of ESO 459-G13.
The candidate is not present on images taken by Puckett on Sept. 19
(limiting mag about 20.0) or on Palomar Sky Survey plates taken on
1992 May 29 (limiting mag about 21.0) and 1974 July 23 (limiting
mag about 20.0).


V1187 SCORPII
     R. J. Rudy, D. K. Lynch, and R. W. Russell, The Aerospace
Corporation; and S. J. Bus, University of Hawaii, report infrared
spectroscopy of V1187 Sco between 0.8 and 5 microns using the
Infrared Telescope Facility (+ SpeX).  The object entered its
coronal phase around the middle of September, with the appearance
of the [S VIII] and [S IX] lines on Sept. 22.  Further observations
on Sept. 30 revealed more and strengthening coronal lines.
Currently present are [S VIII] at 0.99 microns and [S IX] at 1.25
microns, [Si VI] and [Si VII] at 1.96 and 2.48 microns, and weak
[Ca VIII] at 2.32 microns.  Despite the existence of coronal
features and the emission lines of He II, fluorescently excited
lines of O I persist.  Brackett_alpha is strong, and there are
weak, unidentified features at 3.82 and 3.91 microns with broad
flat-topped or castellated profiles similar to the hydrogen lines.
There is no evidence that dust formation has occurred.
