BOAO meaning in Academic & Science ?

The list of asteroid-discovering observatories contains a section for each observatory which has discovered one or more asteroids, along with a list of those asteroids.

For each numbered asteroid, the Minor Planet Center lists one or more discoverers who have been given credit for the discovery. Sometimes these are individuals (by modern rules there can be no more than three co-discoverers), and sometimes the credit is given to an organization (for instance, Purple Mountain Observatory).
