Photometric observations at the Oakley Observatory in Terre Haute, Indiana, during 2007 were used to build a light curve for 892 Seeligeria. The asteroid displayed a rotation period of 15.78 ± 0.04 hours and a brightness variation of 0.35 ± 0.07 in magnitude.[3]
Seeligeria is a member of the Alauda family (902),[1] a large family of typically bright carbonaceous asteroids and named after its parent body, 702 Alauda.[4]: 23
