We have obtained R-band images of the error box of GRB 020409
(Piro 2002, GCN 1347) using the IC AMER 2m telescope at peak Terskol and
MPAE two-channel focal reducer.
Twelve 600s images were taken on 2002 April 10 at 19:33 UT.
The second epoch three 600s images were taken on 2002 April 12 at 00:51 UT.
We find no evidence that any object in the BeppoSAX error box varies by
more than approximately 0.5 mag.
The limiting magnitude of this search is approximately R = 22.
