Images taken during the following two nights showed the source to fade, and this further supports the identification. The following image has a dimension of 5 x 4 arcmin.
North is up and East is to the left.
Since the limiting magnitude of the DSS image is at least 21, the new source is most likely the optical counterpart of GRB 990712. Further observations are urged. Note that the Magnitudes given in the GCN were based on the red-magnitudes of the USNO stars in the field. Subsequent standard star observations revealed that the USNO magnitudes were off by as much as 2 magnitudes in a few cases.
