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…
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…
Velocities measured in small scale solar magnetic elements
Øystein Langangen, Mats Carlsson, Luc Rouppe van der Voort +1
We have obtained high resolution spectrograms of small scale magnetic structures with the Swedish 1-m Solar Telescope. We present Doppler measurements at $0\farcs{2}$ spatial resol…
