Polymeric jets throw light on the origin and nature of the forest of solar spicules
Sahel Dey, Piyali Chatterjee, Murthy O. V. S. N. +4
Spicules are plasma jets, observed in the dynamic interface region between the visible solar surface and the hot corona. At any given time, it is estimated that about 3 million spi…
Tracing the magnetic field topology of the quiet corona using propagating disturbances
Huw Morgan, Marianna Korsos
The motion of faint propagating disturbances (PD) in the solar corona reveals an intricate structure which must be defined by the magnetic field. Applied to quiet Sun observations…
An improved method for estimating the velocity field of coronal propagating disturbances
Huw Morgan, Marianna Korsos
The solar corona is host to a continuous flow of propagating disturbances (PD). These are continuous and ubiquitous across broad regions of the corona, including the quiet Sun. The…
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…
Comparative case study of two methods to assess the eruptive potential of selected active regions
Francesca Zuccarello, Ilaria Ermolli, Marianna B. Korsos +4
Solar eruptive events, like flares and coronal mass ejections, are characterized by the rapid release of energy that can give rise to emission of radiation across the entire electr…
Testing and Validating Two Morphological Flare Predictors by Logistic Regression Machine Learning
M. B. Korsos, R. Erdelyi, J. Liu +1
Whilst the most dynamic solar active regions (ARs) are known to flare frequently, predicting the occurrence of individual flares and their magnitude, is very much a developing fiel…
Differences in periodic magnetic helicity injection behaviour between flaring and non-flaring Active Regions: Case Study
M. B. Korsos, P. Romano, H. Morgan +3
The evolution of magnetic helicity has a close relationship with solar eruptions and is of interest as a predictive diagnostic. In this case study, we analyse the evolution of the…
Solar Flare Prediction Using Magnetic Field Diagnostics Above the Photosphere
M. B. Korsos, M. K. Georgoulis, N. Gyenge +7
In this article, we present the application of the weighted horizontal gradient of magnetic field (WGM) flare prediction method to 3-dimensional (3D) extrapolated magnetic configur…
Investigation of pre-flare dynamics using the weighted horizontal magnetic gradient method: From small to major flare classes
Marianna B. Korsos, Shuhong Yang, Robert Erdelyi
There is a wide range of eruptions in the solar atmosphere which contribute to space weather, including the major explosions of radiation known as flares. To examine pre-event beha…
Applying the weighted horizontal magnetic gradient method to a simulated flaring Active Region
M. B. Korsos, Piyali Chatterjee, R. Erdelyi
Here, we test the weighted horizontal magnetic gradient () as a flare precursor, introduced by Korsos et. al. (2015, ApJ, 802, L21), by applying it to a magneto-hydrodynamic…
Spatial Inhomogeneity In Solar Faculae
A. Elek, N. Gyenge, M B. Korsós +1
In this paper, we investigate the inhomogeneous spatial distribution of solar faculae. The focus is on the latitudinal and longitudinal distributions of these highly localised feat…
On the evolution of pre-flare patterns of a 3-dimensional model of AR 11429
M. B. Korsos, S. Poedts, N. Gyenge +6
We apply a novel pre-flare tracking of sunspot groups towards improving the estimation of flare onset time by focusing on the evolution of the 3D magnetic field construction of AR…
Detailed analysis of dynamic evolution of three Active Regions before flare and CME occurrence at the photospheric level
Yudong Ye, M. B. Korsos, R. Erdelyi
We present a combined analysis of the applications of the weighted horizontal magnetic gradient (denoted as WG_M in Korsos et al., ApJ, 802, L21, 2015) method and the magnetic heli…
An application of the weighted horizontal magnetic gradient to solar compact and eruptive events
M. B. Korsos, Michael S. Ruderman, R. Erdelyi
We propose to apply the weighted horizontal magnetic gradient (), introduced in Korsos et al (2015), for analysing the pre-flare and pre-CME behaviour and evolution of Acti…
Dynamic Precursors of Flares in Active Region NOAA 10486
M. B. Korsos, N. Gyenge, T. Baranyi +1
Four different methods are applied here to study the precursors of flare activity in the Active Region NOAA 10486. Two approaches track the temporal behaviour of suitably chosen fe…
Pre-Flare Dynamics of Sunspot Groups
M. B. Korsos, T. Baranyi, A. Ludmany
Several papers provide evidences that the most probable sites of flare onset are the regions of high horizontal magnetic field gradients in solar active regions. Besides the locali…
Statistical relationship between the succeeding solar flares detected by the RHESSI satellite
L. G. Balázs, N. Gyenge, M. B. Korsós +3
The Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) has observed more than 80,000 solar energetic events since its launch on February , 2002. Using this…
Study of sunspot group morphological variations leading to flaring events
M. B. Korsos, T. Baranyi, A. Ludmany
It is widely assumed that the most probable sites of flare occurrences are the locations of high horizontal magnetic field gradients in the active regions. Instead of magnetograms…
