OH MASER IN MARKARIAN 273
     L. Botinelli, D. Fraix-Burnet, L. Gouguenheim, A. M. le
Squeren, and I. Patey, Observatoire de Paris, Meudon, telex: "In a
recent OH survey of IRAS galaxies with high infrared (100-micron)-to-
blue luminosity ratio made with the Nancay radio telescope, we
detected a new powerful OH maser in the peculiar galaxy Mrk 273 (OH
luminosity [1667 MHz] = 350 LO for an adopted distance of 150 Mpc).
We have also detected a wide (about 450 km/s) H I absorption centered
at the velocity 11 245 km/s."


COMET MACHHOLZ (1985e)
     The following visual magnitude estimate has been reported by
D. Machholz, Loma Prieta, CA (0.25-m reflector): June 9.45 UT, 8.2.

     For the benefit of radio and infrared astronomers, the following
ephemeris is provided to link those published on IAUC 4071-4072
(note that the comet will be at elongation 2.2 deg on June 28.0 ET).
