During the 2003 Halloween storms, an interplanetary magnetic cloud event provided an exceptionally long period of more than 30 hours of stable solar wind conditions with a nearly purely northward IMF. Meanwhile, the four Cluster spacecraft were in the tail, observing a gradual transition from a "normal" hot and tenuous plasma sheet to a cold and dense plasma sheet, as a result of the IMF turning and staying northward.
