摘要

The magnetic reconnection process at the Earth's magnetopause is observed at various times and places as either anti-parallel or component reconnection. The two scenarios are combined in a model known as the Maximum Magnetic Shear model, which predicts the location of long and continuous reconnection X-lines across the dayside magnetopause along the ridge of maximum magnetic shear. This study investigates a Magnetospheric Multiscale Mission (MMS) magnetopause encounter where the spacecraft had repeated contact with the boundary layers for about 40 min. While in contact with the magnetopause boundary layers, the Interplanetary Magnetic Field (IMF) slowly and continuously rotated,magnetically connecting the MMS spacecraft to different sections along an extended dayside reconnection X-line. These magnetic connection points slide along component reconnection tilted X-lines and also connect several times to the anti-parallel section of the magnetopause X-line. Despite the continuously changing IMF conditions, each magnetopause boundary layer encounter shows accelerated ion beams,indicating an active reconnection X-line at the magnetopause that covers a length of about 20 R_E.
