Antidipolarization fronts observed by ARTEMIS

Using three years of ARTEMIS data, our results describe sharp, highly asymmetric north-then-south bipolar magnetic field variations that mirror Earthward dipolarization fronts. These do not fit the classical plasmoid model and so we call them antidipolarization fronts. Read more.

ARTEMIS observations of extreme diamagnetic fields in the lunar wake

While crossing through the lunar wake, the ARTEMIS probes have observed diamagnetic fields compressed to over twice the interplanetary magnetic field strength correlated with high plasma beta conditions in the solar wind. Read more.

Azimuthal Extent and Properties of Mid-tail Plasmoids From Two-point ARTEMIS Observations at the Earth-Moon Lagrange Points

For the first time, ARTEMIS is able to provide direct two-point observations at X~ -60 RE, where plasmoids have newly originated. We estimate the typical plasmoid extent at the mid-tail region by the correlation between the two-point observations. Read more.

Size and shape of the distant magnetotail

We present the predictions of the BATS-R-US model for magnetotail and bow shock cross sections at lunar distance as a function of IMF strength and orientation. The cross section of the distant magnetotail responds almost immediately to abrupt transitions in the IMF orientation. These transitions cause changes in the location of reconnection on the dayside magnetopause as well as the locations where the resulting newly reconnected magnetic field lines enter the magnetotail.
