First Observations of a Geomagnetic Superstorm With a Sub‐L1 Monitor

Space Weather
Forecasting the geomagnetic effects of solar coronal mass ejections (CMEs) is currently an unsolved problem. CMEs, responsible for the largest values of the north‐south component of the interplanetary magnetic field, are the key driver of intense and ...

Simultaneous Two‐Point Study of the Martian Bow Shock Affected by an Interplanetary Coronal Mass Ejection: Tianwen‐1 and MAVEN Observations

Geophysical Research Letters
The Martian bow shock (BS) plays a significant role in the Martian plasma environment. Based on observations from Tianwen‐1 and MAVEN, we first report two cases of simultaneous two‐point crossings of the Martian BS affected by an interplanetary coronal ...

Solar Cycle Dependence of Migrating Diurnal Tide in the Equatorial Mesosphere and Lower Thermosphere

Remote Sensing
Atmospheric migrating diurnal tide (DW1) is one of the prominent variabilities in the mesosphere and lower thermosphere (MLT). The existence of the solar cycle dependence of DW1 is debated, and there exist different and even opposite findings at ...
