Another fast-moving asteroidal object has been discovered by
C. and E. Shoemaker with the 0.46-m Schmidt telescope at Palomar:
1987 UT R.A. (1950) Decl. Mag.
Sept.27.30850 0 42 01.95 - 6 04 02.1 16
27.33923 0 41 58.28 - 6 03 37.8

30.40138 0 36 08.17 - 5 23 49.7
The object is evidently a borderline Apollo, but the semimajor
axis is completely indeterminate:
T = 1987 June 27.99 ET
