Measurements of plasma motions in dynamic fibrils
Oystein Langangen, Luc Rouppe van der Voort, Yong Lin
We present a 40 minute time series of filtergrams from the red and the blue wing of the \halpha line in an active region near the solar disk center. From these filtergrams we const…

Spectroscopic measurements of dynamic fibrils in the Ca {\small{II}} 8662 Å line
Oystein Langangen, Mats Carlsson, Luc Rouppe van der Voort +2
We present high spatial resolution spectroscopic measurements of dynamic fibrils (DFs) in the Ca {\small{II}} 8662 Å line. These data show clear Doppler shifts in the identified DF…
