Abstract

IC 342 recently has been observed in total and polarized intensity at λ20 cm with the VLA in its D-configuration. The angular resolution is 45” HPBW corresponding to a resolution in the plane of the galaxy of 750 × 680 pc (RA × DEC), assuming a dis-tance of 3.1 Mpc [1]. The polarized intensity is shown in Fig. 1. The emission is asymmetric with respect to the major axis: In the western part the structure is very fragmentary, but in the eastern part two long ridges of polarized intensity are prominent. The outer one can be traced along about 20 kpc. Both ridges coincide with two optical spiral arms and two HI spiral arms[2]. The region of maximal polarized intensity is near the bifurcation of the optical and HI spiral arms.
