We will present the microlocal properties of a limited data transform in thermoacoustic tomography. We consider the case in which data are recovered on a small circular arc, and we use microlocal analysis to prove how the reconstruction operator $R^*R$ adds artifacts unless one truncates smoothly at the boundaries of the arc. We prove generalizations to the three-dimensional case and provide a framework for other limited data problems.
