COMET MACHHOLZ (1978l)
     The following positions have been reported:

     1978 UT          R. A. (1950) Decl.    m1
     Sept.14.32986    6 37 57    -19 50.7   11
          15.476      6 37.3     -20 50

H.-E. Schuster (European Southern Observatory).
E. Everhart (Denver, Colorado).  Very difficult in moonlight.


PERIODIC COMET GICLAS (1978k)
     The following precise position has been measured by C.-Y. Shao
from an exposure with Harvard Observatory's 41-cm astrograph:

     1978 UT            R. A. (1950) Decl.
     Sept. 14.32358   0 07 16.65   -10 09 22.1

     The following improved elliptical elements, by B. G. Marsden,
satisfy the five available observations within 1".5:

       T = 1978 Nov. 21.998 ET
   Peri. = 246.320                    e =   0.52645
   Node  = 142.281    1950.0          a =   3.71339 AU
   Incl. =   8.866                    n =   0.137736
       q =   1.75847 AU               P =   7.16 years


EPHEMERIDES OF MINOR PLANETS FOR 1979
     Subscribers are advised that copies of Efemeridy Malykh Planet
for 1979 have now arrived from the Institute for Theoretical Astronomy,
Leningrad, and are available from the Minor Planet Center/Central
Telegram Bureau at the postal address given above.


CORRIGENDA
     On IAUC 3247, the time of the last observation of the undesignated
comet should read 1977 July 19.66848 UT, not July 19.68848.
     In IAU Trans. XVB, p. 189, the figures in the table indicating
the reliability of telegraphed orbits should read 1, 2, 3/4, 5, 6/
7, 8, 9, not 1, 2, 3/4, 2, 3/7, 5, 6.


1978 September 18              (3269)              Brian G. Marsden
