1982 RB
     H.-E. Schuster, European Southern Observatory, provides the
following semiaccurate positions, the first three of which replace
those on IAUC 3725:

      1982 UT           R.A. (1950.0)  Decl.   Mag.

      Sept. 14.12286    23 04.09   -23 53.8    17
            14.16441    23 04.14   -23 56.4
            15.11285    23 05.34   -24 51.5
            19.29132    23 10.47   -28 27.0
            21.07917    23 12.94   -29 49.5


SUPERNOVA IN NGC 1332
     D. A. Allen, Anglo-Australian Observatory; and A. Evans,
University of Keele, report that this object (cf. IAUC 3684) has
formed a dust shell at a temperature of ~ 1100 K.  The 2.2-micron
(K band) magnitude ~ 14.  Information regarding the ejection
velocity and the form of the visual light curve is urgently
required for a complete interpretation.  Evans requests that such
information be sent to him at the address: Department of Physics,
The University, Keele ST5 5BG, England.


2 CETI AND lambda ERIDANI
     P. K. Barker, Department of Astronomy, University of Western
Ontario, reports his discovery that 2 Cet = HR 9098 is a Be star;
H-alpha image-dissector-scanner observations on Sept. 5 show
centrally-reversed emission superposed on photospheric absorption.
Further, the bright Be star lambda Eri = HR 1679 is entering a new
active emission phase; H-alpha observations on Sept. 8 show centrally-
reversed emission above the continuum.  From 1980 Sept. to 1981 Oct.
H-alpha in lambda Eri has shown only broad photospheric absorption.


COMET AUSTIN (1982g)
     Total visual magnitude, coma diameters and tail length estimates
by J. Bortle, Stormville, NY: Sept. 4.04 UT, 6.1, 4'.0, - (10x50
binoculars); 6.04, 6.3, 4'.5, - (10x50); 10.05, 6.7, 4', 10' in p.a.
39 (10x50); 12.05, 6.9, 3'.5, 5' in p.a. 35 (10x50); 20.03, 7.8, 4'.2,
5' in p.a. 48 (20x80 binoculars).
