Ion Kinetics in a Hot Flow Anomaly: MMS Observations [PDF]

Geophysical Research Letters, 2018
AbstractHot Flow Anomalies (HFAs) are transients observed at planetary bow shocks, formed by the shock interaction with a convected interplanetary current sheet. The primary interpretation relies on reflected ions channeled upstream along the current sheet. The short duration of HFAs has made direct observations of this process difficult.

A hot flow anomaly at Mars

Geophysical Research Letters, 2015
AbstractOne of the most important modes of planet/solar wind interaction are “foreshock transients” such as hot flow anomalies (HFAs). Here we present early observations by the NASA Mars Atmosphere and Volatile EvolutioN spacecraft, confirming their presence at Mars and for the first time at an unmagnetized planet revealing the underlying ion ...

Ion‐Scale Flux Rope Observed inside a Hot Flow Anomaly

Geophysical Research Letters, 2020
AbstractWe report an earthward moving ion‐scale flux rope embedded within the trailing edge of a hot flow anomaly (HFA) observed by the Magnetospheric Multiscale satellite constellation on 17 December 2016 upstream of Earth's quasi‐parallel bow shock.

Hot flow anomaly observed at Jupiter's bow shock

Geophysical Research Letters, 2017
AbstractA Hot Flow Anomaly (HFA) is created when an interplanetary current sheet interacts with a planetary bow shock. Previous studies have reported observing HFAs at Earth, Mercury, Venus, Mars, and Saturn. During Juno's approach to Jupiter, a number of its instruments operated in the solar wind.

Magnetic flux rope formation within a magnetosheath hot flow anomaly [PDF]

Journal of Geophysical Research: Space Physics, 2012
We report observations on 1 March 2004 by the Cluster spacecraft of a hot flow anomaly (HFA) encountered in the dayside magnetosheath near Earth's bow shock. Embedded within the HFA was a magnetic flux rope with a diameter of a few thousand km, which was moving sunward and was presumably expanding.

Asymmetric magnetosphere deformation driven by hot flow anomaly(ies) [PDF]

Geophysical Research Letters, 2012
We present a case study of a large deformation of the magnetopause on November 26, 2008. The investigation is based on observations of five THEMIS spacecraft located at the dawn flank in the magnetosphere and magnetosheath, on Cluster measurements at the dusk magnetosheath, and is supported by ACE solar wind monitoring. The main revelation of our study

Global ULF waves generated by a hot flow anomaly [PDF]

Geophysical Research Letters, 2017
AbstractHot flow anomalies (HFAs), which are frequently observed near Earth's bow shock, are phenomena resulting from the interaction between interplanetary discontinuities and Earth's bow shock. Such transient phenomena upstream the bow shock can cause significant deformation of the bow shock and the magnetosphere, generating traveling convection ...

A statistical study on hot flow anomaly current sheets [PDF]

Journal of Geophysical Research: Space Physics, 2017
AbstractHot flow anomalies (HFAs) are phenomena frequently observed near Earth's bow shock and form when the interplanetary discontinuities interact with Earth's bow shock. We perform a statistical study to determine what kind of discontinuities are more efficient to generate HFAs.
