ISEE-3 magnetometer observations are presented that are consistant with flux ropes within the magnetotail. Three instances have been found. The flux ropes are identified by a strong magnetic field in their core, a bipolar magnetic field signature, and a double peaked field signature indicative of an offcenter crossing. The axes of the flux ropes lie nearly parallel to the magnetotail axis. Inside the flux ropes, a hot plasma streams tailward and there is an increase in the flux of energetic protons and the intensity of plasma waves. When the flux ropes were observed, ground magnetograms near local magnetic midnight were highly disturbed.
