Deep VLT/FORS1 R_C-band (top) and HAWKI K_s-band image (bottom) of the XRT error circle of GRB 080915A taken 28 h after the burst. Also shown is the 90% c.l. XRT error circle (), as well as a circle of radius 2r₀. In the K_s-band image, object E is not visible and, therefore, is indicated by a cross. Note that all objects visible in the ISAAC image have a counterpart in the FORS1 image taken 11 days later.
