In October, the Navy Prototype Optical Interferometer (NPOI) was renamed the Navy Optical Interferometer (NOI), reflecting the instrument’s evolution into a very productive, modern research tool. The NOI is the result of a collaborative effort between the U.S. Naval Observatory, the Naval Research Laboratory, and Lowell Observatory. The NOI will be expanded in the coming years with the addition of new imaging stations (called siderostats) to the array, a new 6-telescope beam combiner, and other facility upgrades.
