Abstract
The Jodrell Bank Mark I paraboloid has been used to map a large area between 8 h and 16 h R.A. and +18° and −36° declination, at a frequency of 240 Mc/s and with a resolution of 1°. A new method of scanning was employed. The results show that even at high galactic latitudes the main ridge of the Spur encloses an area of complicated structure, where the most prominent features are highly elongated. An analysis of the geometry of the Spur supports the conclusion that it lies closely on a small circle of diameter 113° and centred at lII = 330°, bII = 19°.5. The brightness distribution is consistent with the Spur being a shell source of emission.Keywords
