It was named after German astronomer Hugo Hans von Seeliger. 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.Seeligeria is a member of the Alauda family ({{small|902}}),[1] a large family of typically bright carbonaceous asteroids and named after its parent body, 702 Alauda.[7]{{rp|23}} References1. ^1 {{Cite web |url=http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=892;cad=1 |title=892 Seeligeria (1918 DR) |work=JPL Small-Body Database |publisher=NASA/Jet Propulsion Laboratory |access-date=3 May 2016}} [2][3]2. ^1 2 {{cite web |title = Small Bodies Data Ferret |work = Nesvorny HCM Asteroid Families V3.0 |url = https://sbntools.psi.edu/ferret/PropertySearch/familyForm.action |accessdate = 7 November 2017}} 3. ^1 {{Cite journal |first1 = D. |last1 = Nesvorný |first2 = M. |last2 = Broz |first3 = V. |last3 = Carruba |date = December 2014 |title = Identification and Dynamical Properties of Asteroid Families |url = https://arxiv.org/pdf/1502.01628.pdf |journal = Asteroids IV |pages = 297–321 |bibcode = 2015aste.book..297N |doi = 10.2458/azu_uapress_9780816532131-ch016 |arxiv = 1502.01628 |accessdate = 7 November 2017}} }} External links
