SOTSP: HOP 373 filament @S20
2019-09-27T07:31:00 to 2019-09-27T08:18:24
Science Goal: Formation and destabilisation of filaments
Program: Fast map, 230"x164", Q65, 1-side CCD
Target: Active Region
xcen=782 ycen=-374
Instrument: SOTSP
HOP/JOP: 206
Description: Main Objective: SOT/SP would measure the parasitic polarities in the barbs of filaments. Scientific Justification: Filaments are formed with shear flows in channel. It will be interesting to detect the footpoints of filament and mass motions inside the barbs and along the filaments. Spectroscopic observations on the disk in chromosphere lines (Mg II h and k, Halpha) and photosphere lines are required to show the dynamics of the filament by counter-streaming or by turbulence. HMI continua and magnetogram will provide data to follow the large scale evolution of the channel. With HMI surface velocities by using CST (LCT) methods will be determined leading to an estimate of the shear at large scale of the filament and Hinode/SOT will locate the parasitic polarities where the filament has its footpoints.
