We observed the position of the INTEGRAL hard X-ray transient IGR J18284-0345 and its Swift XRT counterpart (Blanchard et al., ATel #1981) in the I- band, using the MDM 1.3m telescope on 2009 March 21 11:48 UT. No optical counterpart is detected to a limiting magnitude of I=20 in a 15 minute exposure. The surrounding region is largely devoid of stars, which can be related to the high extinction estimates, E(B-V) = 3.49, A(V)=11.57, A(I)=6.77 derived by Schlegel et al.
