We examine spectral time series of coronal line Mg ix 368 Å and transition region line O v 629 Å, observed with the Coronal Diagnostic Spectrometer (CDS) onboard the SOHO spacecraft. Primarily we were looking for intensity and velocity oscillations in polar plumes, however by chance we detected a giant macro-spicule at the limb and were able to follow its dynamical structure. Blue and red-shift...

Aims. Off-the-limb observations with high spatial and spectral resolution will help us understand the physical properties of spicules in the solar chromosphere. Methods. Spectropolarimetric observations of spicules in the He  10830 Å multiplet were obtained with the Tenerife Infrared Polarimeter on the German Vacuum Tower Telescope at the Observatorio del Teide (Tenerife, Spain). The analysis ...

ABSTRACT We perform a 2.5D magnetohydrodynamic simulation to gain comprehensive understanding of the formation spicule-like cool jets caused by initial transverse velocity pulses akin Alfvén in solar chromosphere. invoke multiple (Vz) between 1.5 and 2.0 Mm atmosphere, which create perturbations. These transfer energy non-linearly field-aligned perturbations via ponderomotive force. This physic...
