He MiaoA statistical test of superluminal motion &in Yi-ping, Xie Guang-zhong, than, & Fan Jun-hui Yunnan Observatory, Chinese Academy of Sciences, Kunming 650011 Using the data of superluminal motion listed in AAnS 1995, 36, 147, we show that the standard cosmological model, the relativistic beaming model and the synchrotron selfCompton mechanism together provide a consistent and reasonable interpretation of the superluminal motion.

The relation between ascending prominence and coronal mass ejection Wu Guiping, Xu Ao-ao & Yao Rue-xin Faculty of Physics, Nanjing Railway Medical College, Nanjing 210009
On the basis of the close relation between ascending prominences and coronal mass ejections (CME) and the dynamics of prominences, we study the dynamical evolution of the helmet loop above an ascending prominence under the action of the background magnetic field, with particular reference to the events of 1980-08-18. We found 1) that the slowly ascending prominence caused only a slow evolution of the loop, 2) that the acceleration and ultimate velocity of the prominence determined the degree of violence of the CME, and 3) that the energy of the CME probably came from the magnetic energy released by the eruptive prominence.

Highly sheared configurations and many flares occur across the 2nd and 3rd lines, including separatrices

Comet Hale-Bopp was observed at the Yunuan Observatory using a newly commissioned 1024x 1024 CCD camera attached to our 1 m telescope in February and March, 1996. Our results indicate systematic deviations from Yeoman’s ephemerides for 1966-02-22 and our measured
