SMARPs and SHARPs: Two Solar Cycles of Active Region Data
Monica G. Bobra, Paul J. Wright, Xudong Sun +1
We present a new data product, called Space-Weather MDI Active Region Patches (SMARPs), derived from maps of the solar surface magnetic field taken by the Michelson Doppler Imager…
A Machine Learning Dataset Prepared From the NASA Solar Dynamics Observatory Mission
Richard Galvez, David F. Fouhey, Meng Jin +8
In this paper we present a curated dataset from the NASA Solar Dynamics Observatory (SDO) mission in a format suitable for machine learning research. Beginning from level 1 scienti…
First NuSTAR Limits on Quiet Sun Hard X-Ray Transient Events
Andrew J. Marsh, David M. Smith, Lindsay Glesener +16
We present the first results of a search for transient hard X-ray (HXR) emission in the quiet solar corona with the \textit{Nuclear Spectroscopic Telescope Array} (\textit{NuSTAR})…
Observations of Reconnection Flows in a Flare on the Solar Disk
Juntao Wang, P. J. A. Simoes, N. L. S. Jeffrey +3
Magnetic reconnection is a well-accepted part of the theory of solar eruptive events, though the evidence is still circumstantial. Intrinsic to the reconnection picture of a solar…
Microflare Heating of a Solar Active Region Observed with NuSTAR, Hinode/XRT, and SDO/AIA
Paul J. Wright, Iain G. Hannah, Brian W. Grefenstette +7
NuSTAR is a highly sensitive focusing hard X-ray (HXR) telescope and has observed several small microflares in its initial solar pointings. In this paper, we present the first join…
Evidence of Significant Energy Input in the Late Phase of a Solar Flare from NuSTAR X-Ray Observations
Matej Kuhar, Säm Krucker, Iain G. Hannah +15
We present observations of the occulted active region AR12222 during the third {\em NuSTAR} solar campaign on 2014 December 11, with concurrent {\em SDO/}AIA and {\em FOXSI-2} soun…
