IR 1017+08 AND Zw 475.056
     I. F. Mirabel, University of Puerto Rico, writes: "OH maser
emission from the galaxies IR 1017+08 and Zw 475.056 was discovered
using the Arecibo radio telescope.  The isotropic luminosities
at 1667 MHz are 463 and 7 LO, respectively (assuming H = 75
km s**-1 Mpc**-1).  In the direction of IR 1017+08 no H I emission
and/or absorption could be detected at the 1667-MHz recession
velocity of 14 720 km/s; the ratio of the peak lines at 1667 and
1665 MHz is greater than 15."
