The first radio pulsar, CP 1919, with a pulse period of 1.337 seconds and a pulse width of 0.04 second, was discovered by Jocelyn Bell in the constellation of Vulpecula, just south of Cygnus. in July 1967. The present day designation of this pulsar is PSR 1919+21: pulsar at right ascension 19 hours 19 minutes, declination 21 degrees.
