Fox (Penn State) report on behalf of a larger collaboration:\n\nWe have imaged the field of GRB070219 (Sakamoto et al., GCN 6104)) with\nthe Gemini Multi-Object Spectrograph mounted on the Gemini North\nTelescope.  Images consisted of 4 x 180 s exposures in z' and 2 x 180 s\nexposures in i' at a mean epoch of approximately 14:50 19 February UT (~\n13.7 hr after the burst).  Inside the revised XRT error circle (Starling\net al., GCN 6112), we see no sources to limiting magnitudues of i' >\n23.0, z' > 22.0.  Photometric calibration was performed relative to the\nSDSS fields provided by Cool et al. (GCN 6105)",
