SUPERNOVAE
B. Szeidl, Konkoly Observatory, Budapest, telexes the discovery
by M. Lovas of supernova 1985J 9" east and 5" north of the
nucleus of an anonymous galaxy at R.A. = 11h12m2, Decl. = +34deg06'
(equinox 1950.0). The object was at mpg = 14.0 on May 10.
A. Chalabaev and S. Cristiani, European Southern Observatory,
report that spectra obtained on May 10 at the La Silla 2.2-m
telescope in the range 350-560 nm (resolution 0.4 nm) with the ESA
photon-counting detector show supernova 1985I to be of type I,
near maximum light, closely resembling supernova 1981B (Branch et
al. 1983, Ap.J. 270, 123). The redshift velocity of the galaxy
defined at the [O II] 372.7-nm and the Ca II H and K lines is 8600
+/- 100 km/s. The declination given on IAUC 4058 should be negative.
H0323+022
A. V. Filippenko, University of California at Berkeley; and
W. L. W. Sargent, California Institute of Technology, report that
high-quality spectra of the rapidly-variable x-ray source H0323
+022 (Doxsey et al. 1983, Ap.J. 264, L43) reveal an absorption-
line redshift z = 0.147 +/- 0.001. Observations were made with the
Hale 5-m telescope for one hour on Feb. 24, when the nonstellar
continuum was fainter than usual. The strongest lines in the
nucleus are Na D, Ca II H and K, and the G band (430.4 nm). These
new data confirm the hypothesis of Margon and Jacoby (1984, Ap.J.
286, L31) that H0323+022 is an extragalactic BL-Lac object rather
than a galactic star.
EXO 1846-031
W. Wenzel, Sonneberg Observatory, reports that examination of
745 Sonneberg sky-patrol plates taken by H. Huth between 1954 and
1985 Apr. 20 and reaching mag 13-14 shows no object at the
position given on IAUC 4051, 2' south preceding SAO 142658.
