摘要：
We report total-power observations at 1435 MHz of the Upper-Scorpius region. The spectral index distribution has been computed using available data from a previous 408 MHz all-sky survey by Haslam et al. (1981). An extended spur-like structure dominated by nonthermal emission has been detected surrounding the region. We discuss the origin and nature of this region on the basis of a model of the interaction between a shock front and a cloudy ISM. Several physical parameters are estimated.
