---

1998OR₂= D99PMJ is an Amor asteroid discovered with NEAT on 24 July 1998 and followed up by others. It was moving 0.4 degrees/day with V = 18.8. It is a Potentially Hazardous Asteroid, determined to be 1-3 km (1 mile) in the latest orbital solution. It poses no immediate threat to the Earth. It poses no immediate threat to the Earth. It has a,e,i,q = 2.36067, 0.56575, 5.865, 1.025 (G. Williams, MPC).

1998OH = D7HYU0 is an Apollo Earth-crossing asteroid discovered with NEAT on 19 July and recovered on subsequent nights. It was moving 0.4 degrees/day with V = 18.2. Prediscovery observations by F. Seelos and K. Lawrence using PCAS data (E.Helin, PI) combined with other observations confirm it to be 2-4 km in diameter, making it the largest Potentially Hazardous Asteroid discovered since 1990, although it is of no immediate threat to the Earth. It is of no immediate threat to the Earth. It has a,e,i,q = 1.54, 0.41, 25, 0.9150 (G. Williams, MPC).

D8IOXD, a candidate Near-Earth Asteroid, was discovered with NEAT on 22 July 1998. It was moving 0.47 degrees/day with magnitude V = 16. It has not been recovered for 5 nights and is considered lost.

NEAT serendipitously observed Comet LINEAR M2 on 19 July 1998.
