摘要

Observations of the synchronous double asteroid (3905) Doppler were carried out during a campaign of 3 months between October 2017 and December 2017. Several eclipse events of 0.2–0.3 mag were recorded. We refined the rotational period to 50.826 ± 0.002 h. The J2000 ecliptic coordinates of the pole of the system are: λ = 215 ± 2° and β = 65 ± 2°.
