I had hoped my explanation near the lower right of the map would be sufficient. Apparently not. Those numerals represent the number hours before or after the closest approach of the asteroid to Earth at 19:24:41 UT. Each oneís placement is at the location where the asteroid will appear in the zenith at that time.
