The abrupt and permanent changes of the photospheric magnetic field in the localized regions of active regions during solar flares, called magnetic imprints (MIs), have been observed for nearly the past three decades. The well-known coronal implosion model is assumed to explain such flare-associated changes but the complete physical understanding is still missing and debatable. In this study, we made a systematic analysis of flare-related changes of the photospheric magnetic field during 21… 



Investigating the Magnetic Imprints of Major Solar Eruptions with SDO/HMI High-Cadence Vector Magnetograms

The solar active region photospheric magnetic field evolves rapidly during major eruptive events, suggesting appreciable feedback from the corona. Previous studies of these “magnetic imprints” are

A Statistical Study of the Magnetic Imprints of X-class Solar Flares

Magnetic imprints, the rapid and irreversible evolution of photospheric magnetic fields as feedback from flares in the corona, have been confirmed by many previous studies. These studies showed that

Statistical Study of Magnetic Nonpotential Measures in Confined and Eruptive Flares

Using Solar Dynamics Observatory/Helioseismic and Magnetic Imager vector magnetic field observations, we studied the relation between the degree of magnetic non-potentiality with the observed

First Detection of Chromospheric Magnetic Field Changes During an X1-Flare

Stepwise changes of the photospheric magnetic field, which often becomes more horizontal, have been observed during many flares. Previous interpretations include coronal loops that contract, and it

Photospheric and Coronal Observations of Abrupt Magnetic Restructuring in Two Flaring Active Regions

For two major X-class flares observed by the Solar Dynamics Observatory (SDO) and the Solar TErrestrial RElations Observatory Ahead (STEREO-A) spacecraft when they were close to quadrature, we

The magnetic nature of solar flares

AbstractThe main challenge for the theory of solar eruptions has been to understand two basic aspects of large flares. These are the cause of the flare itself and the nature of the morphological

Flare-productive active regions

This review focuses on the formation and evolution of flare-productive ARs from both observational and theoretical points of view and shows that the improvement of observational instruments and modeling capabilities has significantly advanced understanding in the last decades.

Changes of Magnetic Structure in Three Dimensions Associated with the X3.4 Flare of 2006 December 13

Recent observations demonstrated that sunspot structure can change rapidly and irreversibly after flares. One of the most puzzling results is the increase in magnetic shear around the flaring

Longitudinal Magnetic Field Changes Accompanying Solar Flares

We have used Global Oscillation Network Group (GONG) magnetograms to characterize the changes in the photospheric longitudinal magnetic field during 15 X-class solar flares. An abrupt, significant,

Analysis and modelling of recurrent solar flares observed with Hinode/EIS on March 9, 2012

Three homologous C-class flares and one last M-class flare were observed by both the Solar Dynamics Observatory (SDO) and the Hinode EUV Imaging Spectrometer (EIS) in the AR 11429 on March 9, 2012.
