B2 1506+34
     I. Kazes and J. Crovisier, Observatoire de Paris, Meudon; D.
Despois, Observatoire de Bordeaux; and J. M. Dickey, University of
Minnesota, report: "In a recent extragalactic OH survey with the
Nancay radio telescope, we detected the radio source B2 1506+34,
which is identified with a 15.6-mag peculiar galaxy (Colla et al.
1975, A. Ap. Suppl. 20, 1).  The spectrum displays a prominent
absorption in both mainlines 1665 (C = 0.035) and 1667 (C = 0.07)
MHz; the line widths are ~ 135 km/s.  Furthermore, some maser
emission is suggested around 13 600 km/s.  This is the first strong
molecular absorption detected at a distance of 270 Mpc."


LILLER'S VARIABLE IN NORMA
     Further to the item on IAUC 4035, H. Drechsel and A. C. Danks
used the European Southern Observatory 1-m telescope with the InSb
detector and obtained the following photometric magnitudes (+/- 0.01)
on Feb. 8 UT: J = 6.53; H = 5.41; K = 4.95; L = 4.47; M = 4.58 (+/-
0.10).  These colors again confirm the object as a very-late-type
star, with strong infrared excess.
