摘要：

We present near-infrared photometric and speckle interferometric observations showing long-term changes in the apparent nature of the circumstellar shell surrounding IRC + 10216. We consider both models in which dynamical changes occur in the shell and in which the direct light from the star to a portion of the shell is blocked by intervening material.
