A surface brightness map and point-wise photometry at 10 μm of the infrared reflection nebula GSS30 were made with the Wyoming 2.3 m telescope. Extended emission is detected as far as 10 arc seconds north of the illuminating star, IRS 1. The photometry shows that the nebular surface brightness is a factor of three more than that expected from thermal emission from dust grains. If the 10 μm flux is due to scattering, then grains with a radius of 1.6 μm are required. Alternatively, the 10 μm flux is consistent with the flux expected from the unidentified IR emission features at 7.7, 8.6, and 11.3 μm.
