Comments: Discovered with SH4 on the same CCD image. See comments for 1998 SH4.
In the Daily Orbital Update for 14 March 2000, the second opposition recovery of SH4 was reported! For a brief while, it had been known as 2000 EV62. We kept the primary designation.

Comments: Discovered by Keith Rivich on an unused Supernova Search team night. Keith confirmed on the following night, just beating low clouds rolling in from the Gulf.
On 5 March, 2000 (UT), Keith Rivich, Max Eastman and I recovered BC3 for its second opposition. We didn't know it at the time, but someone (probably one of the professional surveys) had recovered it a few days before us (when it was known briefly as 2000 DM71). We kept the primary designation. BC3 was tagged many times in the next month.

Comments: Discovered by Keith Rivich while continuing our attempts to recover his and Cynthia's Christmas Eve discovery of 1997 (1997 YC8). This asteroid was found near the predicted position of YC8, but it's motion rapidly diverged from YC8's, so it had to be a new object.

Comments: This discovery ended a long discovery drought. We shot 40 fields in July-August of 1999 without finding a single (unknown) moving object. Usually we have a good chance at discovery (~80%) if we shoot eight fields. On 9/9/99 (local time) we shot four fields, finding three moving objects not listed in the MPC database (plus the known object 5149). We were "scooped" on two of the objects, but the first one we kept.
