Extended Magnetic Reconnection across the Dayside Magnetopause
Berchem, J.; Lavraud, B.; Wild, J. A. +18 more
The extent of where magnetic reconnection (MR), the dominant process responsible for energy and plasma transport into the magnetosphere, operates across Earth’s dayside magnetopause has previously been only indirectly shown by observations. We report the first direct evidence of X-line structure resulting from the operation of MR at each of two wi…
Reconnection at High Latitudes: Antiparallel Merging
Escoubet, C. P.; Dunlop, M. W.; Fear, R. C. +5 more
New investigations have renewed the debate on the occurrence of magnetic reconnection of Earth’s dayside magnetopause. Here, we show for the first time strong evidence for a high-latitude reconnection site, located on initially closed field lines, where the magnetic field orientations inside and outside the magnetopause are close to antiparallel. …
