Eleanor Helin, Jet Propulsion Laboratory, reports that she has
discovered a fast-moving asteroidal object on an exposure with the
1.2-m Schmidt telescope at Palomar as follows:
1982 UT R. A. (1950) Decl. Mag.
Feb. 13.24375 10 13.8 +30 15 18.5
The daily motion is 1o.88 westward (and slightly southward); the
sense of motion seems to be unambiguous.

J. Gibson, Jet Propulsion Laboratory, informs us that he has
recovered this Alinda-type object at Palomar as follows:
1982 UT R. A. (1950) Decl. Mag.
Feb. 2.52781 15 29 39.39 -18 19 52.8 19.5
3.53892 15 35 42.31 -18 12 26.0
The indicated correction to the prediction (MPC 5840, IAUC 3653,
IAUC 3658) is Delta-T = -0.43 day. A revised ephemeris follows:
