Abstract

Using time-resolved two-dimensional aperture photometry we have put upper limits on the pulsed emission from two proposed optical counterparts for PSR B1951+32. Our pulsed upper limits of m(upsilon,pulsed) 23.3, m(b,pulsed) 24.4, for the first candidate and m(upsilon,pulsed) 23.6, m(b,pulsed) 24.3 for the second, make it unlikely that either of these is, in fact, the pulsar. We discuss three further candidates, but also reject these on the basis of timing results. A search of a 5.5 x 5.5 area centred close to these stars failed to find any significant pulsations at the reported pulsar period.
