GOES class estimation for behind-the-limb solar flares using MESSENGER SAX
Erica Lastufka, Säm Krucker
Mercury mission MESSENGER's %(MErcury Surface, Space ENvironment, GEochemistry, and Ranging Solar Assembly for X-rays (SAX) observed almost 700 solar flares between May 28, 2007 an…
Multiwavelength Stereoscopic Observation of the May 1, 2013 Solar Flare and CME
Erica Lastufka, Säm Krucker, Ivan Zimovets +7
A M-class behind-the-limb solar flare on 1 May 2013 (SOL2013-05-01T02:32), accompanied by a ( 400 km/s) CME was observed by several space-based observatories with different v…
NuSTAR Observation of Energy Release in Eleven Solar Microflares
Jessie Duncan, Lindsay Glesener, Brian W. Grefenstette +6
Solar flares are explosive releases of magnetic energy. Hard X-ray (HXR) flare emission originates from both hot (millions of Kelvin) plasma and nonthermal accelerated particles, g…
FOXSI-2 Solar Microflares II: Hard X-ray Imaging Spectroscopy and Flare Energetics
Juliana T. Vievering, Lindsay Glesener, P. S. Athiray +7
We study the nature of energy release and transfer for two sub-A class solar microflares observed during the second flight of the Focusing Optics X-ray Solar Imager (FOXSI-2) sound…
Radio and X-ray Observations of Short-lived Episodes of Electron Acceleration in a Solar Microflare
Rohit Sharma, Marina Battaglia, Yingjie Luo +2
Solar flares are sudden energy release events in the solar corona, resulting from magnetic reconnection, that accelerates particles and heats the ambient plasma. During a flare, th…
The Solar Orbiter Science Activity Plan: translating solar and heliospheric physics questions into action
I. Zouganelis, A. De Groof, A. P. Walsh +182
Solar Orbiter is the first space mission observing the solar plasma both in situ and remotely, from a close distance, in and out of the ecliptic. The ultimate goal is to understand…
The Solar Orbiter mission -- Science overview
D. Müller, O. C. St. Cyr, I. Zouganelis +32
Solar Orbiter, the first mission of ESA's Cosmic Vision 2015-2025 programme and a mission of international collaboration between ESA and NASA, will explore the Sun and heliosphere…
Propagation Effects in Quiet Sun Observations at Meter Wavelengths
Rohit Sharma, Divya Oberoi
Quiet sun meterwave emission arises from thermal bremsstrahlung in the MK corona, and can potentially be a rich source of coronal diagnostics. On its way to the observer, it gets m…
Solar activity classification based on Mg II spectra: towards classification on compressed data
Sergey Ivanov, Maksym Tsizh, Denis Ullmann +2
Although large volumes of solar data are available for study, the vast majority of these data remain unlabeled and are therefore not amenable to supervised machine learning methods…
New light on an old problem of the cores of solar resonance lines
Philip Judge, Lucia Kleint, Jorrit Leenaarts +2
We re-examine a 50+ year-old problem of deep central reversals predicted for strong solar spectral lines, in contrast to the smaller reversals seen in observations. We examine data…
Measurement of magnetic field and relativistic electrons along a solar flare current sheet
Bin Chen, Chengcai Shen, Dale E. Gary +8
In the standard model of solar flares, a large-scale reconnection current sheet is postulated as the central engine for powering the flare energy release and accelerating particles…
High-resolution observations of the solar photosphere, chromosphere and transition region. A database of coordinated IRIS and SST observations
L. H. M. Rouppe van der Voort, B. De Pontieu, M. Carlsson +30
NASA's Interface Region Imaging Spectrograph (IRIS) provides high resolution observations of the solar atmosphere through UV spectroscopy and imaging. Since the launch of IRIS in J…
NuSTAR Observation of a Minuscule Microflare in a Solar Active Region
Kristopher Cooper, Iain G. Hannah, Brian W. Grefenstette +5
We present X-ray imaging spectroscopy of one of the weakest active region (AR) microflares ever studied. The microflare occurred at 11:04 UT on 2018 September 9 and we studie…
Accelerated electrons observed down to <7 keV in a NuSTAR solar microflare
Lindsay Glesener, S"am Krucker, Jessie Duncan +6
We report the detection of emission from a non-thermal electron distribution in a small solar microflare (GOES class A5.7) observed by the Nuclear Spectroscopic Telescope Array (Nu…
FOXSI-2 Solar Microflares I : Multi-instrument Differential Emission Measure Analysis and Thermal Energies
P. S. Athiray, Juliana Vievering, Lindsay Glesener +8
In this paper we present the differential emission measures (DEMs) of two sub-A class microflares observed in hard X-rays (HXRs) by the FOXSI-2 sounding rocket experiment, on 2014…
