Search for high velocities in the disk counterpart of type II spicules
Ø. Langangen, B. De Pontieu, M. Carlsson +3
Recently, De Pontieu et al. (2007b) discovered a class of spicules that evolves more rapidly than previously known spicules, with rapid apparent motions of 50--150 km s, t…

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…
