Computers can learn to find solar flares in vast streams of images and help scientists issue timely space weather alerts, according to a new NSF-funded study. The research was published in the Journal...
Astronomers have made a significant step toward confirming a proposed explanation for how solar flares accelerate charged particles to speeds nearly that of light. This important advance was made poss...
On the injection of helicity by shearing motion of fluxes in relation to Flares and CMEs

An investigation of helicity injection by photospheric shear motions is presented for two active regions, NOAA 11158 and 11166, using LOS magnetic field observations obtained from the Helioseismic and...
Are gravitational waves from giant magnetar flares observable?
gravitational giant magnetar observable
2011/10/18
Are giant flares in magnetars viable sources of gravitational radiation? Few theoretical studies have been concerned with this problem, with the small number using either highly idealized models or as...
Quasi-Periodic Pulsations in Solar Flares: new clues from the Fermi Gamma-Ray Burst Monitor
Sun: fl ares Methods:data analysis Methods: statistical Methods:observational
2011/10/8
In the last four decades it has been observed that solar flares show quasi-periodic pulsations (QPPs) from the lowest, i.e. radio, to the highest, i.e. gamma-ray, part of the electromagnetic spectrum....
Comparison of seismic signatures of flares obtained by SOHO/MDI and GONG instruments
Comparison seismic signatures obtained instruments
2011/9/30
The first observations of seismic responses to solar flares were carried out using time-distance (TD) and holography techniques applied to SOHO/MDI Dopplergrams obtained from space and un-affected by ...
The Flares Associated with the Dynamics of the Sunspots
Sunspots rotation magnetic flux magnetic reconnection
2010/9/16
In the present study, we consider six years data of spot groups that have well developed leading and following spots obtained from the Kodaikanal Observatory white light pictures and occurrence of Hα ...
North–South Distribution of Solar Flares during Cycle 23

2010/9/16
In this paper, we investigate the spatial distribution of solar flares in the northern and southern hemispheres of the Sun that occurred during the period 1996 to 2003. This period of investigation in...
We reinvestigate the problem of Hα intensity oscillations in large flares, particularly those classified as X-class flares. We have used high spatial and temporal resolution digital observations obtai...

Analysis of Enhanced Velocity Signals Observed during Solar Flares
Sun:oscillations Sun:sunspots Sun:flares
2009/5/7
Solar flares are known to release a large amount of energy. It
is believed that the flares can excite velocity oscillations in active regions.
We report here the changes in velocity signals in three...
We reinvestigate the problem of Hα intensity oscillations in
large flares, particularly those classified as X-class flares. We have used
high spatial and temporal resolution digital observations obt...

Sun: corona flares coronal mass ejections
2009/5/6
Solar flares and coronal mass ejections convert large amounts
of magnetic free energy into thermal, kinetic and potential energies, and
into energy of non-thermal particles. The partitioning among t...
