Abstract The discovery of variable NIR polarization in the star-forming region W33C IRS 3 and IRS 1 is reported. The polarization for both of these sources varies on time scales of a few years. For IRS 3, the K polarization ranges from a low of about 1 percent in the late 1970s to about 20 percent in 1985. Between 1985 and 1989, the K polarization of IRS 1 dropped from about 19 percent to about 3 percent. The observed polarization properties and variations of both IRS 1 and IRS 3 can be explained by a clumpy disk in IRS 3.
