     M. Turatto, G. Altavilla, S. Benetti, E. Cappellaro, and A.
Pastorello, Osservatorio di Padova; and A. Clocchiatti, Pontificia
Universidad Catolica (PUC) de Chile, report the discovery of a new
supernova (V = 22.4) on three images taken on Nov. 17.09 UT with
the 2.2-m telescope (+ WFI) at the European Southern Observatory
(ESO), La Silla, in the course of the PUC-Padova Supernova Search.
SN 2000fc is located at R.A. = 0h58m33s.58, Decl. = -27o46'40".1
(equinox 2000.0), which is 0".3 west of the host galaxy's nucleus.
Nothing was present at this location on images taken a year earlier
(cf. SN 1999ey, IAUC 7310).  Comparison of a spectrum (range
598-1025 nm, resolution 1.5 nm), obtained on Nov. 26.10 with the
ESO 3.6-m telescope (+ EFOSC2), with a database of well-observed
nearby supernova spectra indicates that the new object is a type-Ia
event; the best match is obtained with the spectrum of SN 1996X a
few days past past maximum light and redshifted to 0.42.  No direct
measurement of the parent galaxy redshift is possible with the
spectrum obtained.

     A. Retter, Keele University; L. Cook, Concord, CA; R. Novak,
Copernicus Observatory; J. M. Saxton, University of Manchester;
L. T. Jensen, Hundslund, Denmark; and D. Korcakova and J. Janik,
Masaryk University, write: "Analysis of 31 nights of CCD photometry
of V1494 Aql during 2000 June-August suggests a periodicity of
0.13467(2) day, or about twice as long as the signal reported on
IAUC 7448.  The full amplitude of the variation in the R band
increased from 0.03 mag in June to 0.07 mag in August.  The folded
light curve shows a double structure with a shallower dip at phase
0.5, with about half the amplitude of the main periodicity."
     Visual magnitude estimates:  Apr. 1.846 UT, 8.9 (A. Pearce,
Nedlands, W. Australia); May 1.072, 10.1 (M. Lehky, Hradec Kralove,
Czech Republic); June 3.00, 10.0 (K. Sarneczky, Agasvar, Hungary);
July 1.731, 10.5 (S. Yoshida, Ibaraki, Japan); 29.99, 11.0 (J. G. S.
Aguiar, Joaquim Egidio, S.P, Brazil); Sept. 3.00, 11.2 (J. Carvajal,
Avila, Spain); Oct. 2.522, 11.2 (Pearce); Nov. 19.704, 11.5 (Lehky).
