PERIODIC COMET BORRELLY (1980i)
H.-E. Schuster, European Southern observatory, reports that he
has recovered this comet as follows:
1980 UT R. A. (1950) Decl. m1
July 9.31181 23 43.96 -43 32.6
21.34514 23 51.27 -46 30.6 18-18.5
The positions are in close agreement with the ephemeris on MPC 5225.
SUPERNOVA IN ANONYMOUS GALAXY
J. Maza, Department of Astronomy, University of Chile, reports
that E. Gonzalez has found a supernova on a plate taken by Maza of
an anonymous galaxy at R.A. = 23h09m38s, Decl. = -42o05'.9 (equinox 1950.0).
The object is located 3" west and 5" south of the nucleus of the
galaxy; four plates have been found with images of the supernova,
and they provide the following photographic magnitudes: 1980 May
23.326 UT, 16.5; June 13.391, 17.5; July 9.289 (discovery plate),
18.5; July 12.280, 18.5.
NOVALIKE OBJECT IN VULPECULA
A. A. Boyarchuk, Crimean Astrophysical Observatory, communicates:
"T. S. Belyakina, K. K. Chuvaev, R. E. Gershberg and P. P.
Petrov report that on 1980 June 21.9 UT this object dropped to V =
12.1, B = 13.0, U = 13.4. Its spectrum, of the A-type in 1979, is
now a middle or advanced M-type with Ha and Na D emissions but
without any noticeable emission in the green and blue. If the object
is of FU-Ori type, it has an extremely fast-fading flare."
H. M. Maltzen and A. Schnell, Vienna Observatory, report: "We
have observed this object photographically with the 1.5-m
telescope on Mt. Schoepfl; linking the object to NGC 6830, we find:
June 14.01 UT, B = 13.10; June 20.01, V = 12.54, B-V = 0.66."
SS 433
S. van den Bergh, Dominion Astrophysical Observatory, telexes:
"A red (Kodak IIIa-F + RG 645 filter) plate of SS 433 obtained with
the Hale 5-m telescope shows a faint, highly-contorted filament of
length 30" located 7'.6 southeast of SS 433 itself."
