On the differences in the periodic behaviour of magnetic helicity flux in flaring active regions with and without X-class events
Sz. Soós, M. B. Korsós, H. Morgan +1
Observational pre-cursors of large solar flares provide a basis for future operational systems for forecasting. Here, we study the evolution of the normalized emergence (EM), shear…
Active Longitude and Coronal Mass Ejection Occurrences
N. Gyenge, T. Singh, T. S. Kiss +2
The spatial inhomogeneity of the distribution of coronal mass ejection (CME) occurrences in the solar atmosphere could provide a tool to estimate the longitudinal position of the m…
Systematic variations of macrospicule properties observed by SDO/AIA over half a decade
T. S. Kiss, N. Gyenge, R. Erdelyi
Macrospicules (MS) are localised small-scale jet-like phenomena in the solar atmosphere, which have the potential to transport considerable amount of momentum and energy from the l…
Photospheric Logarithmic Velocity Spirals as MHD Wave Generation Mechanisms
S. J. Mumford, R. Erdélyi
High-resolution observations of the solar photosphere have identified a wide variety of spiralling motions in the solar plasma. These spirals vary in properties, but are observed t…
The Dynamics of Rapid Redshifted and Blueshifted Excursions in the Solar Halpha line
D. Kuridze, V. Henriques, M. Mathioudakis +5
We analyse high temporal and spatial resolution time-series of spectral scans of the Halpha line obtained with the CRisp Imaging SpectroPolarimeter (CRISP) instrument mounted on th…
Evidence for the photospheric excitation of incompressible chromospheric waves
R. J. Morton, G. Verth, V. Fedun +2
Observing the excitation mechanisms of incompressible transverse waves is vital for determining how energy propagates through the lower solar atmosphere. We aim to show the connect…
Longitudinal oscillations in density stratified and expanding solar waveguides
M. Luna-Cardozo, G. Verth, R. Erdélyi
Waves and oscillations can provide vital information about the internal structure of waveguides they propagate in. Here, we analytically investigate the effects of density and magn…
Photospheric high-frequency acoustic power excess in sunspot umbra: signature of magneto-acoustic modes
S. Zharkov, S. Shelyag, V. Fedun +2
We present observational evidence for the presence of MHD waves in the solar photosphere deduced from SOHO/MDI Dopplergram velocity observations. The magneto-acoustic perturbations…
