N2 - The results of measurements of the tilt angle of the sunspot magnetic field (MF) axis foractive regions (ARs) of different morphological structure are presented. The data archive ofthe RATAN-600 radio telescope and the NoRH radio interferometer observations was takenand analyzed using a new processing technique. The method is based on the image peculiarities of the cyclotron radiation source over the sunspot and its changes depending on the sunspot coordinates on the disk caused by the rotation of the Sun. Measurements showed that thetilt angle of the sunspot MF axis is quite small (within 1-10°) and practically does not dependon the morphology of AR. At the same time, the MF of the head sunspot in most cases as expected is inclined to the E-limb. Deviations from this rule are presumably explained if thesunspot MF is partially closed upon other ARs located nearby.
