     C. Pollas, Observatoire de la Cote d'Azur (OCA), reports his
discovery of a supernova at R.A. = 2h28m36s.64, Decl. =
+41o56'01".9 (equinox 2000.0), which is 5".0 west and 4".9 south of
the spiral galaxy's center (the galaxy having mag B about 18.5).
Estimated magnitudes for SN 1995aj from OCA Schmidt telescope films
taken by D. Albanese and Pollas:  Sept. 29.06 UT, V about 20.0;
Oct. 25.00, 21.4.  A nearby star (V about 18.4) has position end
figures 36s.64, 21".3.  Nothing is present at this location on the
original Palomar Sky Survey prints or the 1989 (Bj) Palomar Survey
      L. Wang, Department of Astronomy, University of Texas,
communicates:  "A low-resolution (1.2-nm FWHM) spectrogram of SN
1995aj was obtained on Oct. 26 UT with the McDonald Observatory's
2.1-m telescope.  Preliminary inspection of the spectrum shows this
to be a type-Ia supernova about 1 month past maximum."

     N. Houk, University of Michigan, has determined a spectral
type of G2-3 V for 51 Peg from a 1-min IIa-O 10-deg objective-prism
plate taken on 1981 Aug. 6 with the Burrell Schmidt telescope at
Kitt Peak.  The high-quality spectrum (resolution about 0.1 nm;
dispersion 10.8 nm/mm, i.e., normal classification dispersion),
together with the use of several standard spectra, revealed no
duplicity or chemical peculiarities.  The spectrum is definitely
not as luminous as IV (quoted in the 1982 Bright Star Catalogue
from Keenan and Pitts 1980, Ap.J. Suppl. 42, 561), or even 'IV-V'.
It is also earlier than the temperature type of G5 given in several
older publications.

SUPERNOVA 1995ag IN UGC 11861
     Magnitude and precise position obtained by E. Jung, Marl,
Germany, with a 0.20-m reflector (+ CCD) on Oct. 21.840 UT:  R =
16.0, R.A. = 21h56m19s.5, Decl. = +73o15'14".3 (equinox 2000.0).

     Total CCD magnitudes:  Oct. 20.80 UT, 13.4 (T. Kojima,
Chiyoda, Japan, 0.25-m reflector); 21.17, 13.2 (S. Garro, Hautes
Alpes, France, 0.20-m reflector; coma diameter 1'.8).
