Homologous flares and magnetic field topology in active region NOAA 10501 on 20 November 2003
(Springer, 2011-03)
We present and interpret observations of two morphologically homologous flares
that occurred in active region (AR) NOAA 10501 on 20 November 2003. Both flares displayed four homologous Hα ribbons and were both accompanied ...

Origin of the Submillimeter Radio Emission During the Time-Extended Phase of a Solar Flare
(Springer, 2011-11)
Solar flares observed in the 200 - 400 GHz radio domain may exhibit a slowly varying and time-extended component which follows a short (few minutes) impulsive phase and can last for a few tens of minutes to more than ...
X-type interactions of the loops in the flare of 25 September 1997 - Part II
(EDP Sciences, 2001-06)
The interaction of magnetic structures and the conversion of magnetic free energy into heating of the plasma and acceleration of particles are commonly accepted as the origin of solar flares. The 3-dimensional (3D) structure ...

What is the role of magnetic null points in large flares?
(Elsevier, 2007-12)
We have performed the analysis of the magnetic topology of active region NOAA 10486 before two large flares occurring on October 26 and 28, 2003. The 3D extrapolation of the photospheric magnetic field shows the existence ...
Estudo do efeito dos flares na amplitude dos modos acústicos solares
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE FÍSICAPrograma de Pós-Graduação em FísicaUFMG, 2021-06-04)
Helioseismology makes it possible to study the structure and dynamics of the Sun by observing and analyzing the acoustic modes propagating inside it. Solar flares, in turn, are a sudden increase in brightness observed on ...
The 3B/X3 solar flare of 27 February 1992
(Instituto de Geofísica UNAM, 2000-01)
Analizamos la evolución de la región activa (AR) NOAA 7070 y la relacionamos con una fulguración 3B/X3, ocurrida el 27 de febrero de 1992. Las observaciones en rayos X blandos fueron obtenidas por el SXT (Soft X-ray ...
A Burst with Double Radio Spectrum Observed up to 212 GHz
(Springer, 2013-06)
We study a solar flare that occurred on 10 September 2002, in active region NOAA 10105, starting around 14:52 UT and lasting approximately 5 minutes in the radio range. The event was classified as M2.9 in X-rays and 1N in ...
