Joint X-ray, EUV and UV Observations of a Small Microflare
Iain G. Hannah, Lucia Kleint, Säm Krucker +5
We present the first joint observation of a small microflare in X-rays with the Nuclear Spectroscopic Telescope ARray (NuSTAR), UV with the Interface Region Imaging Spectrograph (I…
The Origin of Major Solar Activity - Collisional Shearing Between Nonconjugated Polarities of Multiple Bipoles Emerging Within Active Regions
Georgios Chintzoglou, Jie Zhang, Mark C. M. Cheung +1
Active Regions (ARs) that exhibit compact Polarity Inversion Lines (PILs) are known to be very flare-productive. However, the physical mechanisms behind this statistical inference…
First high-resolution look at the quiet Sun with ALMA at 3 mm
A. Nindos, C. E. Alissandrakis, T. S. Bastian +9
We present an overview of high resolution quiet Sun observations, from disk center to the limb, obtained with the Atacama Large mm and sub-mm Array (ALMA) at 3 mm. Seven quiet Sun…
Magnetic Clouds: Solar Cycle Dependence, Sources, and Geomagnetic Impacts
Y. Li, J. G. Luhmann, B. J. Lynch
Magnetic clouds (MCs) are transient magnetic structures giving the strongest southward magnetic field (Bz south) in the solar wind. The sheath regions of MCs may also carry southwa…
The association of the Hale Sector Boundary with RHESSI solar flares and active longitudes
K. Loumou, I. G. Hannah, H. S. Hudson
The heliospheric magnetic field (HMF) is structured into large sectors of positive and negative polarity. The parts of the boundary between these sectors where the change in polari…
Hard X-Ray Constraints on Small-Scale Coronal Heating Events
Andrew J. Marsh, David M. Smith, Lindsay Glesener +7
Much evidence suggests that the solar corona is heated impulsively, meaning that nanoflares may be ubiquitous in quiet and active regions (ARs). Hard X-ray (HXR) observations with…
A new inner heliosphere proton parameter data set from the Helios mission
D. Stansby, C. S. Salem, L. Matteini +1
In the near future, Parker Solar Probe and Solar Orbiter will provide the first comprehensive in-situ measurements of the solar wind in the inner heliosphere since the Helios missi…
Microwave and Hard X-Ray Observations of the 2017 September 10 Solar Limb Flare
Dale E. Gary, Bin Chen, Brian R. Dennis +8
We report the first science results from the newly completed Expanded Owens Valley Solar Array (EOVSA), which obtained excellent microwave imaging spectroscopy observations of SOL2…
Identifying typical Mg II flare spectra using machine learning
B. Panos, L. Kleint, C. Huwyler +4
IRIS performs solar observations over a large range of atmospheric heights, including the chromosphere where the majority of flare energy is dissipated. The strong Mg II h&k spectr…
Electron Power-Law Spectra in Solar and Space Plasmas
M. Oka, J. Birn, M. Battaglia +10
Particles are accelerated to very high, non-thermal energies in solar and space plasma environments. While energy spectra of accelerated electrons often exhibit a power law, it rem…
Impact of Residual Energy on Solar Wind Turbulent Spectra
Trevor A. Bowen, Alfred Mallet, John W. Bonnell +1
It is widely reported that the power spectra of magnetic field and velocity fluctuations in the solar wind have power law scalings with inertial-range spectral indices of -5/3 and…
The Multi-Instrument (EVE-RHESSI) DEM for Solar Flares, and Implications for Non-Thermal Emission
James M. McTiernan, Amir Caspi, Harry P. Warren
Solar flare X-ray spectra are typically dominated by thermal bremsstrahlung emission in the soft X-ray (10 keV) energy range; for hard X-ray energies (30 keV), e…
NuSTAR Detection of X-Ray Heating Events in the Quiet Sun
Matej Kuhar, Säm Krucker, Lindsay Glesener +5
The explanation of the coronal heating problem potentially lies in the existence of nanoflares, numerous small-scale heating events occuring across the whole solar disk. In this pa…
