AB: A big magnetic storm with Dst of order - 472 nT occurred on November 20, 2003. Cluster spacecrafts passed through the magnetopause at about 16:33:20 on the dusk flank, and crossed LLBL between 14:4:00 and 16:13:20. The dusk electric field component Edusk was observed in LLBL. Edusk is about order of 0 ­C 45 mV/m during big magnetic storm, but Edusk is about order of (-1) ­C 1 mV/m during quiet time. At the same time Edusk is about order of 20-70 mV/m during big magnetic storm in the magnetosheath, and the variance of Edusk is correlative with Bz and V.
