|05-20||C. Denis||Mapping the magnetic field of flare coronal loops||in the short talk I am going to introduce the following paper: "Mapping the magnetic field of flare coronal loops", by Kuridze et al. 2019. https://iopscience.iop.org/article/10.3847/1538-4357/ab08e9/meta I will also briefly discuss on the possibility to derive some physical parameters (e.g. temperature, electron density) of the post-flare loop observed by SDDI on 2017 Sep. 10. This based on the theoretical correlations found by Heinzel, Gouttebroze, Vial (1994).|

|S. Ueno||40 Years History of Spectroscopic Researches using Domeless Solar Telescope of Hida Observatory (1979 – 2018)||
In this year, just 40 years passed after the Domeless Solar Telescope
(DST) was built at Hida Observatory in 1979.
In this talk, I would like to look back on spectroscopic researches
that have been performed in the past 40 years with classifying them by
each observation object, as follows.
Photosphere (Quiet Region)
- Differential Rotation
- Gravitational Redshift
- Line Formation
Chromospheric Small Activities
- Ellerman Bomb & Jet
- Grains, Oscillation
Prominence & Dark Filament
- Quiescent Prominence & Filament
- Active Prominence & Filament
- Kernel (Asymmetry)
Sunspot & Active Region
- Evershed Effect
- Emerging Flux

|C. Denis||Fast-filament eruption detected by SMART/SDDI on 2017 April 23||
Tomorrow in main talk of the solar seminar, I will present progress about
my analysis of the "fast-filament eruption detected by SMART/SDDI
on 2017 April 23".
In the first part of my presentation I am going to discuss the kinematics, while in the second part I will show a very rough estimation of the kinetic and potential energies of the filament eruption.
