During Solar Minimum, the Sun is relatively inactive with few sunspots observed on the solar surface. Consequently, we observe a smaller number of highly energetic events such as solar flares or coronal mass ejections (CMEs), which are often associated with active regions on the photosphere. Nonetheless, our magnetofrictional simulations during the minimum period suggest that the solar corona...

The stellar atmospheric simulation code $\textit{Bifrost}$ is useful for exploring the plasma dynamics of the solar atmosphere, but also for tracking magnetically energetic events that may be efficient in heating the chromosphere and corona. In this study, a cube of quiet Sun was modeled in order to track a) the evolution of quiet Sun photosphere and atmosphere, and b) the effect of a...

The High-Resolution Coronal Imager (Hi-C) was launched for a third time on 29th May 2018, resulting in 329 s of 17.2 nm data of target active region AR 12712 with a cadence of approx. 4 s, and a plate scale of 0.129 arcsec^2/pixel.
Co-aligned with SDO/AIA 17.1nm observations, this presentation outlines investigations of the widths of 49 coronal structures. Firstly, evidence of substructure...

The role of magnetic fields in the chromospheric heating problem remains greatly unconstrained. Most theoretical predictions from numerical models rely on a magnetic configuration, field strength, and connectivity; the details of which have not been well established with observational studies for many chromospheric scenarios. High-resolution studies of chromospheric magnetic fields in plage...

With the advent of next generation high resolution telescopes, our understanding of how the magnetic field is organized in the internetwork (IN) photosphere is likely to advance significantly. We present high spatio-temporal resolution observations that reveal the dynamics of two disk-centre IN regions taken by the GREGOR Infrared Spectrograph Integral Field Unit (GRIS-IFU) with the highly...

High-resolution UV observations of the solar atmosphere, complemented by photospheric measurements conveying information about the magnetic configuration of the region of interest, allow us to investigate the magnetic and plasma processes that drive coronal heating and energy release.

The Nuclear Spectroscopic Telescope Array (NuSTAR) is a hard X-ray focusing telescope designed to observe astrophysical sources, but with the capability of observing the Sun. NuSTAR’s higher sensitivity in the HXR range compared to previous solar X-ray instruments, such as RHESSI, combined with the recent solar minimum has provided a unique opportunity to study the faint HXR emission from...
