1983 SA
     The following precise positions have been measured by E.
Bowell from exposures by B. Skiff with the 0.33-m photographic
telescope at the Lowell Observatory's Anderson Mesa Station.  The
Sept. 10 positions are of prediscovery images.  The first observation
on Oct. 4 is somewhat uncertain.  The object is completely
asteroidal in appearance.

     1983 UT            R.A.    (1950.0)    Decl.      Mag.

     The following improved orbital elements have been determined
by the undersigned from the nine observations Sept. 10-Oct. 4:

         T = 1983 July 26.0703 ET
     Peri. = 316.4871                    e =   0.712077
     Node  = 350.0773   1950.0           a =   4.188002 AU
     Incl. =  30.7200                    n =   0.1149989
         q =   1.205822 AU               P =   8.571 years


SUPERNOVAE
     R. Evans, Maclean, N.S.W., reports his visual detection of a
supernova of mag 14.5 in NGC 1448 (R.A. = 3h42m9, Decl. = -44deg48',
equinox 1950.0) on Oct. 6.6 UT.  The object was apparently quickly
confirmed by T. Cragg at the Anglo-Australian Observatory and by
G. Thompson, Brisbane.  The discoverer gave the offset from the
nucleus as 30" east and 5" north, but there is a possibility that
the object is instead south of the nucleus.

     It appears that the NGC 1265 supernova (IAUC 3873) is in fact
the same foreground star reported in January (IAUC 3769, 3770).


VY SCULPTORIS
     M. S. Cropper and B. Warner, University of Cape Town, report
that this novalike variable (Warner and van Citters 1974, Obs. 94,
116: R.A. = 23h23m7, Decl. = -30deg20', equinox 1900.0) is currently at
mag ~ 18.5.  This is the first recorded low state for this star.
Spectroscopic and photometric observations are encouraged.


1983 October 7                 (3877)              Brian G. Marsden
