Circular No. 3279 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION Postal Address: Central Bureau for Astronomical Telegrams Smithsonian Astrophysical Observatory, Cambridge, MA 02138, U.S.A. TWX 710-320-6842 ASTROGRAM CAM Telephone 617-864-5758 1978 SB G. R. Kastel', Institute for Theoretical Astronomy, Leningrad, and Yu. P. Pskovskij, Sternberg Astronomical Institute, Moscow, cable that Lyudmila I. Chernykh has discovered a fast-moving object at the Crimean Astrophysical Observatory as follows: 1978 UT R. A. (1950) Decl. mpg Sept.27.89242 0 40.3 -17 44 12.5 Oct. 1.83787 0 20.4 -16 04 13.5 H 2155-304 R. E. Griffiths, U. Briel and the HEAO-A3 Group report that they have obtained a small multiplicity of possible positions for a new x-ray source H 2155-304 and that a fourteenth-magnitude object is located near the center of one of these positions, viz. the error box centered at R.A. = 21h55m58s.7, Decl. = -30o27'57" (equinox 1950.0). The error box is ~ 2' long and ~ 30" wide, with the major axis at a position angle of 150o. R. A. Wade, P. Szkody and F. Cordova, California Institute of Technology, report that they have obtained two spectrograms of the above-mentioned object, which is located at R.A. = 21h55m57s.9, Decl. = -30o27'54".0 (equinox 1950.0). The observations were made using the SIT digital spectrograph with 10-A resolution on the 150-cm telescope at Palomar on Aug. 5 and Sept. 23 UT. The spectrum from 3600 to 6800 A appears blue (B-V < 0.1) and featureless (to within 10 percent of the continuum) and cannot be recognized as that of a galaxy or a normal single star. Further optical observations of this peculiar object (i.e., time-resolved photometry and a historical search through old photographic plates) are encouraged. NGC 4945 P. Marques dos Santos and J. R. D. Lepine, Observatono Nacional, Rio de Janeiro, and Universidade Mackenzie, Sao Paulo, report that strong water-vapor emission at 22 GHz was detected from the galaxy NGC 4945 with the 13.5-m Itapetinga radio telescope on Sept. 22 and 23. Three emission features appeared in the spectrum at 675, 698 and 714 km/s (with respect to the local standard of rest), the strongest peak at 675 km/s reaching a flux of 12 Jy. 1978 October 4 (3279) Brian G.
