2026 LD1 and 2018 NC15

 U-Code for asteroid 2026 LD1 is 8 so the uncertainty is exremely high

Backward integration taking into account all big planets plus Ceres, Pallas, Vesta:

it seems that these asteroid are near the end of their synodic cycle on about 16 february 2026.

=== Update --- to avoid sampling errors, just quering JPL Horizons asking for daily resolution:
