SUPERNOVAE 1985B, 1985C, 1985D
     A. Spaenhauer and L. Cameron report their discoveries, using
the 1-m telescope at Las Campanas Observatory, of three supernovae:
(1) Supernova 1985C (B ~ 16.5) was found Feb. 15 near the center of
the Sb galaxy ESO 436-G37 (R.A. = 10h31m28s, Decl. = -27deg44'9, equinox
1950.0); N. Suntzeff confirmed this spectroscopically to be probably
a type-I supernova.  (2) Supernova 1985D (B ~ 18.2) was found
4"6 south and 0"8 west of the center of ESO 264-G32 (R.A. = 10h40m23s,
Decl. = -46deg13', equinox 1985.1) on Feb. 16; spectroscopic confirmation
by Suntzeff reveals emission consistent with a pre-maximum stage.
(3) Supernova 1985B was independently discovered (cf. IAUC 4035)
on Feb. 16 (B ~ 17.5), located 28"8 east and 10" north of the center
of NGC 4045 (R.A. = 12h01m56s6, Decl. = +2deg04'30"2, equinox 1985.1);
Suntzeff has found this to be a type-II supernova.  A telex from
H. Kosai, Tokyo Astronomical Observatory, states that this object
was still at B = 15 on a Kiso Schmidt plate taken Feb. 15.673 UT.


AG DRACONIS
     W. Wenzel, Sonneberg Observatory, telexes that this symbiotic
variable may be developing another outburst; it has been quiescent
for several years (cf. IAUC 3540).  On Feb. 17, Wenzel found U =
10.1, B = 10.7, and V = 9.6.


PG 0834+488
     M. C. Cook, Department of Physics, University of Leicester,
communicates: "EXOSAT observations of the cataclysmic variable PG
0834+488 (Green et al. 1982, PASP 94, 560) have detected a hard,
steady x-ray flux of strength 1.3 x 10**-14 J/m**2/s (2-6 keV) and
photon index 1.16, with a low column density of  2.4 x 10**24 m**-2.
This object also lies inside the error box of the HEAO A-1 source
1H 0832+488.  Detailed optical studies of this object are urged."


PERIODIC COMET AREND-RIGAUX (1984k)
    Total visual magnitude estimates: 1984 Dec. 2.42 UT, 12.4 (C. S.
Morris, Whitaker Peak, CA, 0.25-m reflector); 24.40, 11.8 (J. E.
Bortle, Stormville, NY, 0.32-m reflector); 31.46, 11.8 (Morris);
1985 Jan. 3.50, 11.8 (Morris, near Mt. Wilson, CA); 18.48, 12.2
(Morris); 20.47, 12.0 (Morris).
