51 PEGASI
     W. B. Landsman, Hughes STX; T. Simon, University of Hawaii; M.
Mayor, Geneva Observatory; and I. Skillen, VILSPA Observatory,
communicate:  "We obtained an International Ultraviolet Explorer
(IUE) low-dispersion, short-wavelength observation of 51 Peg on
Nov. 25 (exposure time 360 min).  The spectrum is that of a normal
G dwarf, with no continuum detected shortward of 165.0 nm.  At
160.0 nm, we place an upper limit on the continuum flux of 2.43 x
10E-15 erg cmE-2 sE-1 AE-1.  From this limit, we infer that if a
normal, 0.6-solar-mass white dwarf exists in the system, then it
must be cooler than 10~000 K (for a distance of 17.4 pc).  The
spectrum between 170.0 and 195.0 nm is a very close match to an
archival IUE spectrum of alpha Cen A, scaled by the ratio of the V
magnitudes.  Very weak C II and C IV emission in 51 Peg is detected
with integrated fluxes of 2.5 and 4.0 x 10E-14 erg cmE-2 sE-1,
respectively -- consistent with a solar-activity level and a
rotation period of between 23 and 30 days."


LEONID METEORS 1995
     Various reports, including a summary from J. Rendtel,
International Meteor Organization, indicate that the Leonids in
1995 were evidently less pronounced than in 1994 (cf. IAUC 6109).
Rendtel's data from numerous observers delineate a rather broad
plateau for maximum activity extending from Nov. 17.9 to 18.4 UT
(ZHR about 25-35).


SUPERNOVA 1995an IN UGC 3188
     Magnitude and precise position from H. Tomsik, S. Binnewies,
and P. Riepe (Marl, Germany; 0.45-m f/5 reflector + CCD):  Nov.
20.97 UT, 16.7, R.A. = 4h51m48s.54, Decl. = +8o50'39".7 (equinox
2000.0).


CORRIGENDA
     On IAUC 6264, HT Cassiopeiae, for  17.733, read  18.733.  Add
the negative observation 17.74, [13.0 (Schmeer).  The earliest
positive observation of the star's brightening was that by W.
Warraker on 17.912.  This observation was immediately confirmed by
G. Poyner (Birmingham) and communicated by G. M. Hurst (Basingstoke).
     On IAUC 6265, alpha Monocerotid Meteors 1995, line 13 from
foot, for  K. Sarenczky  read  K. Sarneczky; for  Vertes  read
Gerecse
