SUPERNOVA 2001ep IN NGC 1699
     D. Hutchings and W. D. Li, University of California at
Berkeley, report the discovery by LOTOSS (cf. IAUC 7514) of an
apparent supernova in unfiltered images taken with the Katzman
Automatic Imaging Telescope (KAIT) on Oct. 3.5 (mag about 17.1) and
4.4 UT (mag about 16.8).  SN 2001ep is located at R.A. =
4h57m00s.26, Decl. = -4 45'40".2 (equinox 2000.0), which is 10".2
east and 15".8 south of the nucleus of NGC 1699.  A KAIT image
taken on Sept. 28.4 showed nothing at this position (limiting mag
about 19.0).

     P. R. Holvorcem, Campinas, Brazil, provides the following
precise position (measured using USNO-A2.0 reference stars) for the
object reported on IAUC 7726, from his CCD images taken with a
0.36-m f/3.6 Schmidt-Cassegrain telescope in twilight and with the
star at low altitude on Oct. 3.907 UT, when he found red mag 8.5:
R.A. = 13h55m41s.27, Decl. = -64o15'57".9 (equinox 2000.0).
Holvorcem adds that this object does not appear on the Digitized
Sky Survey.  G. J. Garradd, Loomberah, New South Wales, reports the
following position end figures (mean of three CCD images using 320
UCAC stars; total rms residuals 0".6) obtained with a 0.45-m f/5.4
reflector on Oct. 4.412:  41s.23, 57".1.  A very red star appears
in the USNO-A2.0 catalogue with position end figures 41s.25, 57".6
(red mag 17.6, blue mag 20.8).  Visual magnitude estimates:  Oct.
3.965 UT, 9.7 (A. Amorim, Florianopolis, Brazil); 4.540, 9.7 (A.
Pearce, Nedlands, W. Australia).

     Visual magnitude estimates:  Sept. 17.956 UT, 7.9 (J. G. de S.
Aguiar, Campinas, Brazil); 19.064, 8.0 (R. Shida, Sao Paulo,
Brazil); 20.762, 8.3 (K. Hornoch, Lelekovice, Czech Republic);
25.584, 8.9 (Pearce); Oct. 3.975, 9.3 (Amorim).

    Total visual magnitude estimates:  Aug. 16.99 UT, 13.8 (R. J.
Bouma, Groningen, The Netherlands, 0.31-m reflector); 25.40, 14.3
(A. Hale, Cloudcroft, NM, 0.41-m reflector); Sept. 15.99, 12.3 (J.
Carvajal, Avila, Spain, 0.45-m reflector); 22.02, 12.4 (K.
Sarneczky, Agasvr, Hungary, 0.44-m reflector); 26.98, 11.5 (G.
Sostero, Remanzacco, Italy, 0.45-m reflector); 29.13, 11.5 (Bouma,
0.25-m reflector).
