COMET IRAS (1983k)
A comet accidentally discovered by K. S. Russell on a single
exposure by M. Hawkins with the U.K. Schmidt telescope at Siding
Spring appears to be comet IRAS (1983k). In comparison with its
earlier performance the comet is unexpectedly bright. There is
some evidence of a tail. The positions of the trail ends are:
1984 UT R.A. (1950.0) Decl. m2
Mar. 6.64416 12 10 29.79 -15 50 24.7 16

The following parabolic orbital elements, by the undersigned,
are from observations 1983 July 14-1984 Mar. 6. Residuals of +/- 6"
remain in the positions of the 1984 Mar. 6 trail ends.
