     Charles T. Kowal, Hale Observatories, reports the discovery of
a fast-moving asteroidal object on exposures with the 122-cm
Schmidt telescope at Palomar.  Available positions are:

COMET KOWAL (1977f)
     Kowal also reports the discovery of a comet, diffuse with some
condensation and a tail extending 2' to the northeast:

COMET HELIN (1977e)
     The following precise positions have been reported:

     1977 UT             R. A. (1950) Decl.        m1    Observer

T. Seki (Kochi Observatory, Geisei Station).  40-cm reflector.
P. Jekabsons (Perth Observatory).  Communicated by M. P. Candy, who
   provides a 2-day-arc orbit similar to that on IAUC 3064.
H. L. Giclas (Lowell Observatory).  Measurer: M. L. Kantz.


HEAO-A GUEST INVESTIGATOR PROGRAM
     G. J. Fishman, Marshall Space Flight Center, writes that the
launch of HEAO-A (cf. IAUC 3053) has been delayed until late June
due to a problem in the spacecraft attitude control gyros.


1977 April 26                  (3066)              Brian G. Marsden
