Spectroscopic Signatures Related to a Sunquake
Sarah A. Matthews, Louise K. Harra, Sergei Zharkov +1
The presence of flare related acoustic emission (sunquakes) in some flares represents a severe challenge to our current understanding of flare energy transport processes. We presen…
Atmospheric Response to of an Active Region to new Small Flux Emergence
D. L. Shelton, L. K. Harra, L. M. Green
We investigate the atmospheric response to a small emerging flux region (EFR) that occurred in the positive polarity of Active Region 11236 on 23 \,-\ 24 June 2011. Data from the \…
On the Seismicity of September 7, 2011 X1.8-class Flare
S. Zharkov, L. M. Green, S. A. Matthews +1
We present results of our preliminary analysis of acoustically active X-class flare of September 7, 2011. We report two acoustic sources detected via acoustic holography and verifi…
Properties of the 15 February 2011 Flare Seismic Sources
S. Zharkov, L. M. Green, S. A. Matthews +1
The first near-side X-class flare of the Solar Cycle 24 occurred in February 2011 and produced a very strong seismic response in the photosphere. One sunquake was reported by Kosov…
February 15, 2011: sun-quakes produced by flux rope eruption
S. Zharkov, L. M. Green, S. A. Matthews +1
We present an analysis of the 15 February 2011 X-class solar flare, previously reported to produce the first sunquake in solar cycle 24 (Kosovichev 2011). Using acoustic holography…
Flux Rope Formation Preceding Coronal Mass Ejection Onset
L. M. Green, B. Kliem
We analyse the evolution of a sigmoidal (S shaped) active region toward eruption, which includes a coronal mass ejection (CME) but leaves part of the filament in place. The X-ray s…
