Abstract
The first millisecond pulsar, 1937+2141, has given rise to much observational and theoretical excitement (reviewed in ref. 2). A 20th magnitude red object was proposed earlier as a possible optical counterpart3, but we show here that this is not the case: this object is probably a giant star at a distance of 5–6 kpc. There is no evidence for an optical source brighter than the 23rd red magnitude at the improved optical position. We also present results of the search for the optical counterpart of the new millisecond pulsar 1953+2904. A grid of astrometric offset stars for this source is given, and possibility of optical detection discussed.
