Abstract

Using two-probe ARTEMIS magnetic field and plasma measurements we have accomplished a survey of the occurrence of magnetic reconnection signatures in the distant magnetotail between October 2010 and June 2011. We have considered highly accelerated electron and fast bulk plasma flow events during ARTEMIS tail crossings. Our findings suggest that the deep-tail region between \(-60{R}_{E} < X(\mathit{GSM}) < -40{R}_{E}\) is rather active. Fourteen events have been found exhibiting signatures of magnetic reconnection occurrence during 29 days of plasma sheet crossings. Comparisons with mid-tail surveys of reconnection statistics indicate that the deep-tail region can play a significant role in global magnetosphere dynamics.
