GK PERSEI
     Independently of the announcement (IAUC 3238) of the x-ray
source A0327+43 and its possible association with GK Per, J. Bortle,
Brooks Observatory, noted the star brighter than normal on July
1.31 UT at visual magnitude 12.5.  J. Mattei, AAVSO, communicates
further magnitude estimates: July 4.35, 12.5 (P. Goodwin, Shreveport,
LA); 4.42, 12.7 (J. Morgan, Prescott, AZ).  She adds that at
its last outburst, early in 1975, the star reached magnitude ~ 10.5.


PERIODIC COMET SHAJN-SCHALDACH (1978i)
     Faint, but definitely nonstellar images of this comet have
been recorded by C.-Y. Shao and G. Schwartz with the Harvard
Observatory's 155-cm reflector, as shown below.  The positions are in
very close agreement with the prediction on IAUC 3217.

     1978 UT          R. A. (1950) Decl.       m2
     July  2.30263   22 51.3     - 3 38     20-20.5
           3.26025   22 51.8     - 3 35     20-20.5


PERIODIC COMET ASHBROOK-JACKSON (1977g)
     Bortle provides the following total visual magnitude estimate
(32-cm reflector): July 1.29 UT, 12.9.  Ephemeris on IAUC 3161.


OBSERVATIONS OF MINOR PLANETS
     Precise positions obtained by R. E. McCrosky and Schwartz at
Harvard's Agassiz Station.  Measurers: J. H. Bulger and Shao.

              1977/78 UT          R. A. (1950) Decl.

4U 1626-67
     Corrigendum.  On IAUC 3233, fifth line from end,  for  full
amplitude of 2 percent  read  full amplitude of 4 percent.


1978 July 5                    (3240)              Brian G. Marsden
