NOVA SERPENTIS 1978
     Y. Kozai, Tokyo Astronomical Observatory, communicates the
following precise position, measured by H. Kosai from an exposure by K.
Hamajima with the 105-cm Schmidt telescope at the Kiso Station: R.A. =
17h48m59s.74, Decl. = -14o43'08".2 (equinox 1950.0); at the time (Mar.
4.82 UT) mpg was 8.3.  A spectrogram (2o prism) obtained on Mar.
7.83 UT shows H-alpha emission, and the H-beta and H-gamma lines resemble
those of P Cyg, suggesting that the nova was just past maximum.  Visual
magnitude estimates: Mar. 8.40 UT, 8.6 (T. Schmidt, Colorado
Springs, Colorado); 8.5, 8.5-8.6 (R. Annal, Barstow, California).


PERIODIC COMET TSUCHINSHAN 1 (1978e)
     This comet has been recovered by J. H. Bulger, G. Schwartz and
C.-Y. Shao with the 155-cm reflector at Harvard Observatory's
Agassiz Station, as shown below.  The Feb. 4 image is very weak, the
Mar. 8 image somewhat diffuse with condensation.  The positions are
in very close agreement with the prediction on IAUC 3099.

     1978 UT             R. A. (1950) Decl.       Mag.   Observer
     Feb.  4.05164     2 04 47.59   + 6 28 50.8  20-20.5 Bulger
     Mar.  8.03685     3 06.1       +14 52       ~19.5   Schwartz & Shao


PERIODIC COMET SCHWASSMANN-WACHMANN 1
     J. Bortle, Brooks Observatory, informs us that another outburst
has occurred.  He provides the following total visual magnitude
estimates (32-cm reflector): Mar. 6.07 UT, 13.2; 7.05, 13.0;
8.02, 13.0.  The coma diameter increased from 0'.3 to 0'.5 or more.
On Mar. 7 most of the light was contained in a perfectly stellar
point, which increased in size by Mar. 8 (when seeing was poor).


PERIODIC COMET WOLF-HARRINGTON (1977j)
     The following precise position, by T. Furuta (Tokai), is from
Orient. Astron. Assoc. Comet Bull. No. 159:

     1978 UT             R. A. (1950) Decl.         m1
     Jan.  3.50694     0 10 50.35   +13 40 02.0    14


1978 March 9                   (3188)              Brian G. Marsden
