Effect of transport coefficients on excitation of flare-induced standing slow-mode waves in coronal loops
Tongjiang Wang, Leon Ofman, Xudong Sun +2
Standing slow-mode waves have been recently observed in flaring loops by the Atmospheric Imaging Assembly (AIA) of the Solar Dynamics Observatory (SDO). By means of the coronal sei…
Towards a Quantitative Comparison of Magnetic Field Extrapolations and Observed Coronal Loops
Harry P. Warren, Nicholas A. Crump, Ignacio Ugarte-Urra +3
It is widely believed that loops observed in the solar atmosphere trace out magnetic field lines. However, the degree to which magnetic field extrapolations yield field lines that…
High resolution observations of sympathetic eruptions by NVST
Shangwei Li, Yingna Su, Tuanhui Zhou +3
We investigate two sympathetic filament eruptions observed by the New Vacuum Solar Telescope (NVST) on 2015 October 15. The full picture of the eruptions is obtained from the corre…
Polar Field Correction for HMI Line-of-Sight Synoptic Data
Xudong Sun
This document provides some technical notes on the polar field correction scheme for the HMI synoptic maps and daily updated synchronic frames. It is intended as a reference for th…
