QSO 0716+332
     B. Wills, Department of Astronomy, University of Texas, Austin,
reports a visual-light outburst of this radio source (1950.0
position from University of Texas Radio Astronomy Observatory Sky
Survey, +/- 1" : R.A. = 7h16m04.5s, Decl. = +33deg12'42"), as indicated by
the following magnitudes: 19 (Palomar Sky Survey photo); 1981 Dec.-
1985 Feb. (one or more occasions), 20 or fainter; 1986 Feb. 6, ~ 17
(A. Crotts, McDonald Obs.); Mar. 13, 15.5 (D. Wills, McDonald
Observatory). The spectrum is featureless except for a probable
absorption doublet near 361.9 nm.  A finding chart was published by
Condon et al. (1979, A.J. 84, 149).


omega ORIONIS

     D. P. Hayes, Astronomy Department, Columbia University, writes
that the Be star omega Ori (HD 37490) recently displayed a large
increase in linear polarization.  On Jan. 29, the star's intrinsic
polarization was 0.0 percent, but by Mar. 16 it had increased to a
value of 0.63 percent.  Polarization observations of this star will
continue through mid-April.

SUPERNOVA 1986A IN NGC 3367
     W. S. Penhallow, Physics Department, University of Rhode
Island, also reports a precise position for this object (cf. IAUC
4179): R.A. = 10h43m57.56s, Decl. = +14deg00'50"4 (equinox 1950.0).
