SUPERNOVA 2001cx IN UGC 12266
     C. Yu, M. Modjaz, and W. D. Li, University of California at
Berkeley, report the discovery by LOTOSS (cf. IAUC 7514) of an
apparent supernova (mag about 18.1) in an unfiltered image taken
with the Katzman Automatic Imaging Telescope (KAIT) on June 25.5 UT
(confirmed on an earlier image taken on June 9.5 at mag about 17.9
under partly cloudy conditions).  The new object is located at R.A.
= 22h58m00s.28, Decl. = +6 03'48".4 (equinox 2000.0), which is 2".9
west and 23".3 south of the nucleus of UGC 12266.  A KAIT image
taken on 2000 Dec. 12.3 showed nothing at this position (limiting
mag about 19.0).

     M. Fujii, Okayama, Japan, reports that a spectrum (resolution
about 1 nm; instrumental resolution about 450 km/s) of V1178 Sco
(cf. IAUC 7647, 7650), obtained on June 24.57 UT with a 0.28-m
reflector, shows a very strong H-alpha emission line (FWHM about
1300 km/s) and weaker H-beta.  The signal-to-noise ratio was rather
low due to clouds.

     C. Neiner, Observatoire de Meudon and University of Amsterdam
(UA); H. Henrichs and V. Geers, UA; and J.-F. Donati, Observatoire
de Midi-Pyrenees, Toulouse, write: "The slowly rotating, pulsating,
magnetic star beta Cep (spectral type B1 IVe) has again gone into
an H-alpha emission phase.  In June 1999, H-alpha was still
completely in absorption, with emission nearly absent.  On 2001
June 19, observations made with the Pic du Midi 2-m telescope (+
MuSiCoS spectrograph; resolution 38 000) show the double-peaked
emission (with a stronger red peak) extended above the continuum
from -400 to +400 km/s.  The previous H-alpha outburst occurred in
