Low Frequency Polarization Observations Of The Galactic Radio Emission

Multifrequency polarization observations of a number of regions of the Galaxy in the frequency range 200-1250 MHz have been carried out. The area of enhanced linear polarization at meter wavelengths around alpha(1950) = 4(h)30(m),delta(1950) = 61degrees (1=146degrees47', b=9degrees03') reveals a nonmonotonic, oscillating spectrum of the polarized brightness temperature. On the contrary, the region of the North Celestial Pole (l=123degrees, b= 27degrees24') has practically monotonic spectrum. The possible reasons for this difference are discussed.
