Collaborative Asteroid Rotation Period Discoveries From MPC 171. Thus it would be nearly impossible that a single station can derive the asteroid's rotation period in one lunation.
Collaboration is the key to answer.
Also an important requirement is computer software that is capable to export nightly sessions from one observatory to another to be later combined. A program for this purpose is readily available. Canopus by Brian Warner is mainly focused for such work. Thanks to Brian's effort to produce such program, collaboration between observatories is now possible. The table below show asteroid collaborative projects between MPC 171 Flarestar, MPC 713 Thronton and other observatories.
