SUPERNOVA IN MCG 9-19-19
     Aksenov and Zaitseva, Sternberg Astronomical Institute, cable
that N. Metlova has discovered a supernova 8" east and 5" south of
the galaxy MCG 9-19-19 (R.A. = 11h12m7, Decl. = +56deg11', equinox
1950.0).  The object, detected at the Sternberg Crimean Station, was of
mpg = 16.7 on Feb. 1.87 UT.


EDITORIAL NOTICE
     Since the 'dial-in' service described on IAUC 3908 is working
so satisfactorily, the Central Bureau has decided to discontinue
its automatic telephone-answering system.  TWX communication will
be maintained, of course, and contributors and subscribers are
advised that both the dial-in service and TWX/telex are generally
effective methods to contact the Central Bureau at all times.
Because of the Bureau's very small staff, telephone communication
tends to be less satisfactory, and it would be helpful if telephone
calls were restricted to urgent scientific matters--not to
problems involving subscriptions, which are best handled by mail.
