帕洛马山天文台
Observatories, telescopes and surveys that report astrometric observations of small Solar System bodies to the MPC receive a numeric or alphanumeric code such as 675 for the Palomar Observatory, or I41 for the Palomar Transient Factory, a dedicated survey that was conducted at Palomar Observatory during 2009–2012. On numbering, such an observatory may directly be credited by the MPC as discoverer.
