  We present here the results of a study carried out at the Harvard College
Observatory Plate Collection. We examined 3995 plates covering the error box of
the gamma-ray burst GRB 910122, over a time span of 90 yr (from 1889 to 1979).
The total exposure time is ~0.55 yr. No convincing evidence of optical
transient emission was found within the GRB 910122 IPN error box. However, a
possible OT was found outside the GRB 910122 error box. Optical ground based
observations have revealed a V~22.3 object consistent with the position of the
new object. The colours of the object are typical of a K7/M0 star or a reddened
galaxy, which could have caused the OT, but the fact that the object is far
away from the GRB error box makes both events unrelated.
