【Abstract】 With the observed images provided by the 1.56m telescope of Shanghai Astronomical Observatory, two independent methods are used to orient the spin axis of comet Hale Bopp. The two sets of results thus obtained coincide with each other. The R.A. and the Decl. of the spin axis of the comet are about 0 h14 m32 s and -49°09′35″ (epoch 2000), respectively.更多还原
