Astronomers first detected the JI903+0327 in October 2005 as part of Arecibo's Pulsar ALFA (Arecibo L-band Feed Array) or PALFA Survey, an ongoing sky survey using ALFA -- a system of detectors with seven feeds that enables researchers to image large swaths of sky. Follow-up observations of the pulsar and its companion star used Arecibo, the Robert C. Byrd Green Bank Telescope in West Virginia, the Westerbork Synthesis Radio Telescope in the Netherlands and the Gemini North Observatory in Hilo, Hawaii.
