The variable reflection nebula Cepheus A East.

HODAPP K.W. and BRESSERT E.

Abstract (from CDS):

We report K'-band imaging observations of the reflection nebula associated with Cepheus A East covering the time interval from 1990 to 2004. Over this time the reflection nebula shows variations of flux distribution, which we interpret as the effect of inhomogeneous and varying extinction in the light path from the illuminating source HW2 to the reflection nebula. The obscuring material is located within typical distances of ~ 10 AU from the illuminating source.
