     P. Murdin, Royal Greenwich Observatory, reports the following
measured positions of recent supernovae:

   SN     1988 UT          R. A. (1950)  Decl.         V     Note

  1988A   Feb. 11.257    12 35 12.1    +12 04 50      15.0     1
  1988D        11.076     7 49 14.4    + 2 56 30      16.5     2
  1988E        11.188    12 50 55.7    + 2 26 39      18.5     3

Notes:  1. SN 1988A in M58, observer Allington-Smith; Murdin notes
this to be a type-II SN.  2. SN 1988D in MCG +0-20-006, observer
Murdin; type-I supernova.  3. SN 1988E in NGC 4772 (cf. IAUC 4543),
observer Murdin; type-II supernova well past maximum.

PKS 0422+00
     R. Falomo, Padua; P. Bouchet, European Southern Observatory,
La Silla; and L. Maraschi, E. G. Tanzi, and A. Treves, Milan,
report: "Multifrequency spectrophotometric observations of the BL-
Lac object PKS 0422+00 were obtained on Jan. 10 at a visual brightness
close to the highest yet recorded.  The following fluxes (in
units of 10E-15 erg cm-2 s-1 A-1) were measured:  F(140 nm) = 2.7
(International Ultraviolet Explorer + SWP), F(550 nm) = 2.2 (ESO
1.52-m telescope + CCD spectrograph), F(2200 nm) = 1.0 (ESO 2.2-m
telescope + InSb photometer).  A brightening of factor 2.1 at 140
nm, and of factor 1.7 at 550 nm, is found with respect to our 1987
Aug. observations.  With respect to our 1987 Jan. infrared observations,
when the visual magnitude was similar to that of 1987 Aug.,
the brightening at 2200 nm amounts to a factor of 1.2."

     J. Arnaud, Canada-France-Hawaii Telescope (CFHT); F. Hammer,
Paris-Meudon Observatory; and J. Jones and O. le Fevre, CFHT,
communicate: "From two R-band CCD frames obtained 1987 June 17 at
the prime focus of the 3.6-m CFHT under very good seeing conditions,
we have discovered a faint galaxy (R = 22.0), only 1".3 from
the line-of-sight of QSO 1209+107 (R = 17.6, z = 2.19).  The fainter
galaxy is very likely responsible for the Mg II and Fe II
absorption systems observed at z = 0.64 in the spectrum of the QSO
(cf. Young et al. 1982, Ap.J. Suppl. 48, 455)."

1988 February 11               (4546)            Daniel W. E. Green
