A study of vertical motions in filaments based on Hα observations

  • A.N. Shakhovskaya Crimean Astrophysical Observatory

Abstract

From filtergrams derived in the center of the Hα line and with a shift in the wings 0.25 Å and 0.5 Å obtained at the Crimean coronagraph KG-1 in May–August 2016 we studied the vertical motions of quiescent filaments. The differential images of filaments were constructed in red and blue wings. For these images, using the Doppler effect, we determined areas with rising or descending matter with velocities in the range of 5–20 km/s.
