Scientific paper

We present 430-MHz continuum mapping of a region on the edge of the nearby Loop I (the North Polar Spur) where a semi-circular emission arc is superposed upon the larger feature, showing apparent interaction. This arc could represent the remnant of a second generation supernova resulting from star formation within the compressed cool shell of the Loop I supernova remnant. With a ten-fold smaller beam area than any previous survey of this region, we investigate the nature of the arc, and its relation to Loop I as a promising candidate for the reheating event which has often been invoked to explain the X-ray emission of Loop I.
Arecibo Observatory is operated by NAIC, Cornell University, under a cooprative agreement with the NSF.
