A Case Study on the Impact of Interplanetary Coronal Mass Ejection on the Martian O(1S) 557.7 nm Dayglow Emission Using ExoMars TGO/NOMAD‐UVIS Observations: First Results

Geophysical Research Letters
We report, for the first time, the impact of interplanetary coronal mass ejections (ICME) on the recently discovered O(1S) 557.7 nm dayglow emission in the Martian atmosphere.

Multi-scale energy release events in the quiet Sun: a possible source for coronal heating

Frontiers in Astronomy and Space Sciences
The coronal heating problem remains one of the most challenging questions in solar physics. The energy driving coronal heating is widely understood to be associated with convective motions below the photosphere. Recent high-resolution observations reveal

Bright Dots and Coronal Plume Formation in Sunspot Penumbra

The Astrophysical Journal
Coronal plumes are narrow, collimated structures that are primarily viewed above the solar poles and in coronal holes in the extreme ultraviolet, but also in sunspots.

Evolution of Coronal Jets during Solar Cycle 24

The Astrophysical Journal
The focus of this study is on the spatial and temporal distributions of 2704 solar jets throughout Solar Cycle 24, from beginning to end. This work is a follow-up paper by Liu et al. With this extended data set, we have further confirmed the two distinct

Azimuthal Size Scales of Solar Wind Periodic Density Structures

The Astrophysical Journal
Periodic density structures (PDSs) are quasiperiodic variations of solar wind density ranging from a few minutes to a few hours. PDSs advect with the solar wind and have radial length scales ( L _x ) of tens to several thousand megameters, thus belonging
