SUPERNOVA 1990af IN ANONYMOUS GALAXY
J. Maza, University of Chile; and M. Hamuy, Cerro Tololo
Interamerican Observatory, report the discovery by Roberto Antezana
of a supernova (B about 17) at R.A. = 21h31m07s.7, Decl. =
-62 57'37" (equinox 1950.0), which is 7" west and 7" north of the
nucleus of an anonymous galaxy.  The supernova was found on an 103a-O
plate taken by Hamuy and S. Ormeno with the CTIO Curtis Schmidt
telescope on Oct. 24.072 UT.  Confirmation was made by R.Lamontagne,
whose B and V CCD images with the CTIO 0.9-m telescope on Oct. 28
yield B about 18, B-V = +0.2 to +0.3; the object was somewhat
brighter in both B and V on Oct. 29.

AX PERSEI (cf E457)
As suggested by Stefan Korth this Z And-type cataclysmic variable has
faded. Selected results (partly from IAUC 5126) follow:
Oct. 12.78 UT, 10.5 (J. Speil, Walbrzych, Poland); 16.0, 11.1
(J. E. Bortle, Stormville, NY); 18.92, 10.6 (P. Schmeer,
Bischmisheim, Germany); 22.81, 10.8 (Speil); 24.16, 10.9 (Schmeer);
27.21, 11.4 (Schmeer); 29.89, 11.8 (Speil); 31.84, 11.9 (Schmeer).

PROBABLE DWARF NOVA IN FORNAX
W. Liller, Vina del Mar, Chile, reports his discovery, with a 0.20-m
Schmidt telescope + Problicom, of a very blue stellar object in
outburst, at R.A. = 3h24m49s, Decl. = -34 37'.0 (equinox 1950.0),
providing the following Tech pan film magnitudes:  Oct. 27.28 UT,
12.5; 28.31, 12.5; 29.32, 12.6.  M. Phillips, Cerro Tololo Inter-
american Observatory, reports the following CCD magnitudes obtained
by M. Hamuy and R. Lamontagne with the CTIO 0.9-m telescope on Oct.
29:  B = 12.79, V = 12.69.  Spectra (range 450-680 nm) obtained by
F. Baganoff and J. Maza with the CTIO 1.5-m and 4-m telescopes on
Oct. 29 show broad absorptions of H-alpha, H-beta, He I, and possibly
weak He II 469-nm; there is no evidence that these lines are shifted,
and there are no emission features.  An exposure of the region on
Oct. 23 (+/- 1 day) by M. Wischnjewsky, University of Chile, shows
nothing to B = 19, and nothing is present to the limit of the ESO Sky
Survey.
