Scientific paper

The size of the emission region of NGC 4151 at 11.2 microns has been
measured to be 0.16 + or - 0.04 arcsec (1 sigma). This size is in
agreement with that expected from thermal emission from dust grains
heated by a central luminosity source, but is inconsistent with
nonthermal emission.
