英文摘要	Using the high-resolution vector magnetic field data of the CHAMP satellite, we investigate the distribution of large-scale FACs during the great magnetic storm on Nov. 7-8, 2004. The results show that there are different latitudinal distribution characteristics between the morning sector (0200-0400MLT) and afternoon sector (1400-1600MLT). In morning sector, the extent of FACs expand to higher latitudes along with increasing geomagnetic disturbance, while the afternoon sector FACs expand to lower latitudes. In terms of SYM-H and AE magnetic indices, we find that the large-scale FACs in morning sector are significantly affected by substorm activities, and in afternoon sector the large-scale FACs mainly indicate the fluctuations of the ring current in storm time.
