Scientific paper

Djorgovski identified a candidate optical counterpart of the pulsar PSR 1937+214 with a red-sensitive CCD on a 1-m telescope. Two of the authors have found a bright IR flux of 12.3 mag at 2.2 μm, an image at the plate limit on the red-sensitive glass print of the POSS, and CO absorption bands, all for the red candidate. The authors report here that it is probably an ordinary red giant. They do not find statistically significant pulsations at the pulsar frequency or any harmonic up to the fourth in 6 to 8 arc s fields including both the red candidate and the radio pulsar positions.
