Magnetospheric substorms explosively release solar wind energy previously stored in Earth's magnetotail, encompassing the entire magnetosphere and producing spectacular auroral displays. It has been unclear whether a substorm is triggered by a disruption of the electrical current flowing across the near-Earth magnetotail, at ∼10 RE (RE: Earth radius, or 6374 kilometers), or by the process of magnetic reconnection typically seen farther out in the magnetotail, at ∼20 to 30 RE. We report on… 
Mid‐Tail Magnetic Reconnection Triggering Substorm: A Case Study
Onset of a substorm is closely correlated with the current disruption in the near-Earth magnetotail, about 6~8 RE and magnetic reconnection in the middle magnetotail, around 20~30 RE. It is vital to
Evolution of kinklike fluctuations associated with ion pickup within reconnection outflows in the Earth's magnetotail
Magnetic reconnection (MR) in Earth's magnetotail is usually followed by a systemwide redistribution of explosively released kinetic and thermal energy. Recently, multispacecraft observations from
Magnetotail reconnection onset caused by electron kinetics with a strong external driver
TLDR
It is shown, using spacecraft observations and particle-in-cell (PIC) simulations, that magnetotail reconnection starts from electron reconnection in the presence of a strong external driver and develops into ion reconnection.
Multipoint observations of dipolarization front formation by magnetotail reconnection
[1] We present multipoint observations of magnetotail plasma sheet dynamics during an event in which magnetic reconnection and dipolarization were observed at −16 < X < −15 RE (mid-tail) and at −10 <
On the retreat of near-Earth neutral line during substorm expansion phase: a THEMIS case study during the 9 January 2008 substorm
Abstract. The location of magnetic reconnection in the mid-tail during a substorm was studied in many researches. Here we present multi-point THEMIS observations of a reconnection event in the
Bursty magnetic reconnection at the Earth's magnetopause triggered by high-speed jets
The impact of high-speed jets – dynamic pressure enhancements in the magnetosheath – on the Earth’s magnetopause has been observed to trigger local magnetic reconnection. We perform a
Magnetic reconnection X‐line retreat associated with dipolarization of the Earth's magnetosphere
Magnetic reconnection is the key process of plasma transport in the Earth's magnetotail. The ‘X‐line’ where magnetic field lines reconnect often moves away from the Earth. However, the precise cause
Comment on “Tail Reconnection Triggering Substorm Onset”
TLDR
Evidence is provided that near-Earth current disruption, occurring before the conventional tail reconnection signatures, triggered the onset of a magnetospheric substorm, and the observed auroral intensification and tail reconnections are not causally linked.
Inner magnetospheric onset preceding reconnection and tail dynamics during substorms: Can substorms initiate in two different regions?
We present a detailed ground‐based and in situ examination of two substorms on 9 April 2011 providing one of the most detailed observations of a series of activations to date. Using auroral
Construction of magnetic reconnection in the near‐Earth magnetotail with Geotail
[1] The Geotail spacecraft made in situ observations of magnetic reconnection on 15 May 2003 in the near-Earth magnetotail at a radial distance of 28 RE when a moderate substorm started on the

TLDR
The serendipitous encounter of the Wind spacecraft with an active reconnection diffusion region is reported, in which are detected key processes predicted by models of collisionless reconnection in the magnetotail.

The magnetotail and substorms
The tail plays a very active and important role in substorms. Magnetic flux eroded from the dayside magnetosphere is stored here. As more and more flux is transported to the magnetotail and stored,
