Non-thermal Broadening of IRIS Fe XXI Line Caused by Turbulent Plasma Flows in the Magnetic Reconnection Region During Solar Eruptions
Reeves, Katharine K.; Polito, Vanessa; Chen, Bin +3 more
Magnetic reconnection is the key mechanism for energy release in solar eruptions, where the high-temperature emission is the primary diagnostic for investigating the plasma properties during the reconnection process. Non-thermal broadening of high-temperature lines has been observed in both the reconnection current sheet (CS) and flare loop-top re…
On orbit performance of the solar flare trigger for the Hinode EUV imaging spectrometer
Warren, Harry P.; Ugarte-Urra, Ignacio; Brooks, David H. +1 more
We assess the on-orbit performance of the flare event trigger for the Hinode EUV Imaging Spectrometer. Our goal is to understand the time-delay between the occurrence of a flare, as defined by a prompt rise in soft X-ray emission, and the initiation of the response observing study. Wide (266″) slit patrol images in the He II 256.32 Å spectral line…
