Location of NGC 1851A, with the blue circles corresponding to radius of 0$\stackrel{″}{.}$069 around the position of the pulsar as estimated for the time the left frame was taken (MJD = 55558). Given the small proper motion, correcting for it does not induce any noticeable changes in the position of the pulsar.
