We used a 320 by 240 InGaAs IR camera and a broadband filter centered at 1.565 micron to carry out a sequence of near IR observations at Big Bear Solar Observatory. The target is a delta sunspot and our objective is to study the properties of umbral dots in the opacity minimum. Because of the lower scattering light in IR, we can resolve the very center of the umbra. We discuss the contrasts, sizes, lifetimes and proper motions of umbral dots observed in IR and compared with visible observations.
