在对北极射电连续突进行四次扫描期间进行的软X射线观测提供了额外的证据，证明该突环绕着一个古老的超新星遗迹。根据测量到的X射线发射强度和已知的残骸直径，估计它的年龄是几十万年，超新星属于II型，能量在10的51次方尔格和10的53次方尔格之间。
Soft X-ray observations during four scans across the North Polar radio continuum spur have provided additional evidence that the spur encircles an old supernova remnant. From the measured intensity of the X-ray emission, and the known diameter of the remnant, it is estimated that its age is several hundred thousand years and that the supernova was of Type II, with an energy between 10 to the 51st and 10 to the 53rd ergs.
