We imaged the field of GRB 120320A detected by SWIFT
(trigger 518200) with the UWA Zadko robotic telescope (D=100cm)
located at Gingin, Australia.
The observations started 6.8 hr after the GRB trigger.
The elevation of the field was 49 deg and humid= 63%.
9 images have been maded with a duration of 180.0s each.
At the position of the XRT afterglow (Beardmore et al., GCN 13075),
we do not detect any source with a limiting magnitude of
r = 20.7 on the summed images.
The nearest object, which is about 14 arcsec, in our summed image to
the XRT location, is a SDSS galaxy (J141005.65+084149.2 ) with a
photometric z = 0.34 +- 0.167.
