1991 VK
     E. Helin and K. Lawrence (and the latter should also have been
credited with the discovery of 1991 VE on IAUC 5385) have discovered
another fast-moving asteroidal object with the 0.46-m Palomar
Schmidt, with assistance also from P. Rose:

     1991 UT             R.A. (1950) Decl.       Mag.
     Nov.  1.16337   23 45 14.30   +25 09 34.2   15.5

     Preliminary orbital elements from the above observations by
B. G. Marsden, Harvard-Smithsonian Center for Astrophysics:

     e = 0.50349                      Node  = 294.423   1950.0
     q = 0.91076 AU                   Incl. =   5.390
       a =  1.83431 AU     n = 0.396731     P =   2.48 years

(3288) SELEUCUS
     V. A. Shor, Institute for Theoretical Astronomy, St. Petersburg,
informs us that the magnitudes given for this object in the special
ephemerides on pages 454 and 469-470 of Efemeridy Malykh Planet for
1992 require correction by +14.9.  The values given in the
opposition ephemeris on page 402 are correct.
