Carolyn S. and Eugene M. Shoemaker report the following
precise positions of a fast-moving asteroidal object discovered by
them on exposures with the 0.46-m Schmidt telescope at Palomar:
1987 UT R.A. (1950) Decl. Mag.
May 29.24670 14 29 57.69 +16 46 45.7 16.5
30.34462 14 29 59.10 +15 44 09.5
31.19462 14 30 03.51 +14 57 40.0
31.39132 14 30 03.23 +14 47 06.0
June 1.28247 14 30 09.63 +14 00 30.7
An orbit computation from these positions shows that the
object is of Apollo type:
T = 1987 Mar. 10.745 ET
W = 11.454 e = 0.65616
O = 110.613 1950.0 a = 1.70526 AU
i = 11.080 n = 0.442606
q = 0.58634 AU P = 2.23 years
