COMET C/1998 K2 (LINEAR)
     F. Shelly, Lincoln Laboratory ETS, Socorro, reports that one of the
37 fast-moving objects found in the LINEAR program on May 24 is a new comet.
Computations at the Minor Planet Center then linked this object to one
of 25 fast-movers reported by the program two nights earlier.
