EXTRAGALACTIC CH3CCN
     R. Mauersberger, L. J. Sage, and C. Henkel, Max-Planck-Institut
fur Radioastronomie, Bonn, communicate:  "We have detected
extragalactic CH3CCN (propyne/methyl acetylene), the most
complex molecule known to date outside the Galaxy.  The J = 5-4,
6-5, and 8-7 lines were observed with the IRAM 30-m telescope
near the nucleus of M82.  Several transitions of the K multiplet
of the J = 6-5 spectrum are tentatively resolved, suggesting an
excitation temperature well in excess of 50 K."
