Scientific paper

A search has been made for optical pulses from the 1.6 ms pulsar PSR1937+214 using the 3.9 m Anglo-Australian Telescope. Despite previously reported indications of pulsed emission at this period from the red star discussed by Djorgovski (1982), it is concluded that the results of the search are negative with an upper limit of about 25 on the R magnitude of the pulsed emission. Furthermore, astrometric observations show that the red star is displaced about 2.4 arc s north of the pulsar position; hence, the association is probably a chance one.
