          14.494      6 37.9     -20 00     10.7   Machholz

D. E. Machholz (Loma Prieta, California).  25-cm reflector.  Object
   diffuse with condensation (on Sept. 13 and 14), no tail.
H.-E. Schuster (European Southern Observatory).
E. Everhart (Denver, Colorado).  Object diffuse.


PERIODIC COMET HANEDA-CAMPOS (1978j)
     Further precise positions have been reported as follows:

     1978 UT             R. A. (1950) Decl.        m1   Observer
     Sept. 2.39625    20 52 14.78   -29 53 41.3   10    Herald
           8.23125    21 02 42.22   -33 13 56.4         Giclas

D. Herald (Kambah, near Canberra).  31-cm reflector.
H. L. Giclas (Lowell Observatory).  Measurer: M. L. Kantz.

     Total visual magnitude estimate by C. S. Morris, Prospect Hill
Observatory (20 x 80 binoculars): Sept. 10.20 UT, 9.9.


NOVA CYGNI 1978
     An objective-prism spectrogram, covering the range from Ca II
H and K to H-beta, was obtained on Sept. 13.2 UT by G. Schwartz and C.
Whitney at the Harvard Observatory's Agassiz Station.  It shows P-Cyg
profiles of the moderately strong H and K absorption lines with
weaker emission components.  Numerous other weak emissions and
absorptions were also observed.  The spectrum shows a strong resemblance
to that of DQ Her twelve days after discovery (1934 Dec. 25).

     Visual magnitude estimates: Sept. 13.16, 6.4 (J. Ashbrook, Weston,
Massachusetts); 14.38, 6.4 (C. S. Morris, Prospect Hill Obs.).


1978 September 14              (3267)              Brian G. Marsden
