NOVALIKE VARIABLE IN SAGITTARIUS
     S. Benetti, H. W. Duerbeck, and W. C. Seitter, European
Southern Observatory; and T. Harrison, New Mexico State University,
write:  "CCD spectrograms (439-702 nm, resolution 0.28 nm) taken
of this object (IAUC 6322) by W. Hoff (Astrophysikalisches Institut
Jena) on Feb. 24.4 and 25.4 UT with the ESO 1.52-m telescope (+
Boller & Chivens spectrograph) show a pure absorption-line spectrum
with lines of He I, C I, C II, N I, O I, Si II, and faint lines of
H.  The lines are resolved (FWHM 90-100 km/s), the average
heliocentric radial velocity is +108 km/s, and the strong
interstellar Na I D lines have a radial velocity of +3 km/s.  The
slow brightness evolution, and the C-rich and H-poor spectrum, make
this object the first candidate for a star undergoing its final
helium flash since the eruption of V605 Aql in 1919 (cf. Seitter
1989, IAU Symp. 131, p. 315)."


SUPERNOVA 1996C IN MCG +8-25-47
     P. Sicoli reports the following precise position of SN 1996C,
obtained on Feb. 22.994 UT by A. Testa and P. Ghezzi at Sormano
with the 0.5-m reflector (+ CCD):  R.A. = 13h50m48s.60, Decl. =
+49o19'07".1 (equinox 2000.0).
     D. Balam, University of Victoria, gives the following position
end figures for SN 1996C:  48s.63, 08".3.  The supernova is located
13".4 north and 1".6 west of the galaxy's nucleus; a nearby star (V
= 14.6) has position end figures 47s.80, 18'38".9.  Images (Johnson
V) obtained with the 1.82-m Plaskett reflector of the Dominion
Astrophysical Observatory yielded the following preliminary
magnitudes:  Feb. 24.47 UT, 16.4; 25.40, 16.4.


GK PERSEI
     J. A. Mattei, AAVSO, reports that this old nova (Nova Per
1901) has gone into a minor outburst for the first time since 1992
(when it reached mag 10.3 in late July; cf. IAUC 5558), as
indicated by the following observations reported to the AAVSO:
Feb. 19.03 UT, 12.8 (J. Bortle, Stormville, NY); 20.09, 12.9 (W.
Dillon, Missouri City, TX); 23.13, 13.0 (R. Royer, Lakewood, CA);
23.83, 12.9 (P. Schmeer, Saarbrucken, Germany); 25.05, 12.7 (R. A.
Komorous, London, ON); 25.87, 12.6 (J. R. Osorio, Madrid, Spain);
26.05, 12.4 (J. McKenna, Upper Montclair, NJ).
