IRC+10 420, of spectral type F8 Ia, is a maser in the OH molecule's ground-state lines at 1612, 1665, and 1667 MHz. Two 1612 MHz components are separated by 58 km s/sup -1/, with peak fluxes of 47 and 7 Jy. Upper limits are given for the 1720 MHz OH line and the 22,235 MHz H/sub 2/O line. New infrared data are also presented. (AIP)
