It was discovered on 22 March 1939, by French astronomer Louis Boyer at the Algerian Algiers Observatory, North Africa, and named after Paul Daléra, a friend of the discoverer.
[11] In March 2015, three rotational lightcurves of Daléra were independently obtained by Italian astronomers Maurizio Scardella (D06), Fabio Salvaggio (K54, A81), and Giovanni Casalnuovo (C62) after being reported as a light-curve photometry opportunity at minorplanet.info (CALL).
[7][8][9] Previously, photometric observations at the Palomar Transient Factory in September 2013, gave a longer period of 4.2227 hours and an amplitude of 0.14 magnitude (U=2).
[3] However, based on the low albedos (0.03, 0.08, 0.10) determined by WISE/NEOWISE, Daléra is not a stony but rather a carbonaceous asteroid, which are uncommon in the inner main-belt.
This minor planet was named after Paul Daléra, a friend of the discovering astronomer Louis Boyer.
