There is a 18119 day observation arc, the Condition Code=0 and the Earth MOID=0.109022 AU. The solution date was 2024-May-02 05:51:38 PDT. This object is not on MPC's Potentially Hazardous Asteroids list.

Using MPC's elements for 2024 May 2 0000 UT, ST4v predicts that this object is currently moving slowly through Hercules at 15.5 magnitude, brightening to a peak brightness of 13.4 magnitude on the evening of May 19-20 when it will be traveling through Libra at ~9"/minute and 0.11 AU distant. This NEO will be best visible from the southern hemisphere.
