Scientific paper

The spiral structure of the M31 galaxy is distorted, two-armed and of a trailing type. It can be traced up to ≈1 kpc distance from the centre. The sequences of high brightness regions in the central part resemble a multi-armed spiral structure. In the central part a bar-like formation with ≈6 kpc extension and ≈70° position angle was found. The positions of the spiral arms on the major axis and on the north-west small semi-axis show that the inclination angle of the M31 plane is 12°.9±0°.2.
