COMET C/1999 F1 (CATALINA)
On Apr. 17, T. B. Spahr, Lunar and Planetary Laboratory, reported
the automatic discovery of an object of unusual motion and stellar
appearance in the course of the Catalina Sky Survey (0.41-m
Schmidt + CCD):
     1999 UT             R.A. (2000) Decl.        m2
     Mar. 23.31633   13 22 09.56   - 8 27 59.9   18.3
Spahr obtained follow-up data on Apr. 16 and 17.  Computations by
B. G. Marsden suggested that the object was a long-period comet in
a highly-inclined orbit, yielding an identification in Mar. 13
Spacewatch data.  Further observations (given on MPEC 1999-H09)
produce the orbital elements below.  CCD images (660 s total
exposure) obtained with the Catalina 1.5-m reflector by J.
Bialozynski, D. Dietrich, C. Greenberg, E. Hooper, D. McBee, D.
McCarthy, J. Pici, G. Rudnick, and C. Vedeler, and co-added by C.
W.Hergenrother, show a faint coma of diameter 8"-10".

SUPERNOVA 1999bv IN MCG +10-25-14
Michael Schwartz, Cottage Grove, OR, reports his discovery of an
apparent supernova (mag about 18.1) on an unfiltered CCD frame
taken on Apr. 19.446 UT, utilizing the Tenagra I 0.35-m automated
supernova patrol telescope in Sonoita, AZ.  SN 1999bv is located at
R.A. = 17h22m40s.73, Decl. = +60o00'12".9 (equinox 2000.0), which
is about 2".6 west and 24".3 south of the nucleus of MCG +10-25-14.
The new object was confirmed on a frame taken with the same
equipment on Apr. 20.234.  The object does not appear on either the
first or the second Palomar Sky Survey scans and is absent from
archive images taken on 1998 July 13 and 16 using the same
equipment.  The limiting magnitude on all of the Tenagra I images
of this galaxy is about 19.
