We present 610 and 235 MHz GMRT observations of the supernova remnant (SNR) G11.2—0.3 which shows a very large roation measure gradient (ΔRM∼1600 rad m−2) across it. The GMRT observations are the first high-resolution observations of this object at low frequencies. There are differences between the structure observed at 610 and at 235 MHz only some of which can be explained by free-free absorption.
