论文摘要
分析了彗星29p/Schwassmann-Wachmann 1的光度观测结果。该彗星在水冰升华区域以外的大于5 au的地中心距离时表现出实质性活性。该彗星的CCD图像是在俄罗斯科学院（Sao RAS）的6M望远镜的宽带R滤镜中获得的，并在Terskol天文台的2M望远镜上获得。使用特殊的数字过滤器处理图像的处理使活动结构（JET）可以在彗星的尘埃昏迷中区分。使用互相关方法，分别在2008年12月和2009年2月进行的观测值确定彗星核的旋转周期为12.1和11.7天。讨论了通过不同作者获得的彗星核旋转周期估计估计的差异的可能原因。
The results of the photometric observations of comet 29P/Schwassmann-Wachmann 1 are analyzed. The comet demonstrates substantial activity at heliocentric distances larger than 5 AU, outside the water ice sublimation zone. The CCD images of the comet were obtained in wideband R filters at the 6m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences (SAO RAS) and at the 2m telescope of the Peak Terskol Observatory. The processing of the images with special digital filters allowed the active structures (jets) to be distinguished in the dust coma of the comet. With the cross correlation method, the rotation period of the cometary nucleus was determined as 12.1 and 11.7 days for the observations taken in December 2008, and February 2009, respectively. The probable causes of the difference in the estimates of the rotation period of the cometary nucleus obtained by differen authors are discussed.
