AB: Spectropolarimetric data of the active region 10663 was taken with the CSUN-NSO IR camera and the McMath-Pierce telescope on August 26, 2004 from 16:35 to 21:02 UT. Utilizing the Zeeman split Fe I line near 1565 nm, the data is processed to remove instrumental polarization and a Milne-Eddington inversion technique is applied. The results of the inversion are used to examine the physical properties and radial motions of moving magnetic features which appear to originate in the sunspot penumbra.
