Plasma dynamics in the flaring loop observed by RHESSI

T. Mrozek, R. Falewicz, S. Kolomanski +1

The thick-target model predicts that in flare foot points, we should observe lowering of HXR sources' altitude with increasing energy. The foot point of HXR sources result from the…

Fine structure and long duration of a flare coronal X-ray source with RHESSI and SDO/AIA data

Sylwester Kolomanski, Tomasz Mrozek, Ewa Chmielewska

Coronal X-ray sources (CXSs) are phenomenon very often occurring in solar flares regardless of a flare size, duration or power. The nature of the sources was difficult to uncover f…

Coronal Mass Ejections Associated with Slow Long Duration Flares

U. Bak-Steslicka, S. Kolomanski, T. Mrozek

It is well known that there is temporal relationship between coronal mass ejections (CMEs) and associated flares. The duration of the acceleration phase is related to the duration…

EUV and HXR Signatures of Electron Acceleration During the Failed Eruption of a Filament

A. Netzel, T. Mrozek, S. Kolomanski +1

We search for EUV brightenings in TRACE 171 Å images and HXR bursts observed during failed eruptions. We expect that if an eruption is confined due to interaction with overlying ma…

RHESSI Investigation of X-ray Coronal Sources During Decay Phase of Solar Flares: II. Energy Balance

Sylwester Kolomanski, Zbigniew Koltun, Tomasz Mrozek +1

As it was shown by many authors, a slow decrease in X-rays observed during the decay phase of long duration flares (LDE) can be explained only by a magnetic reconnection and energy…

RHESSI Observations of Long-Duration Flares With Long-Lasting X-ray Loop-Top Sources

Sylwester Kolomanski, Tomasz Mrozek, Urszula Bak-Steslicka

Context: The Yohkoh/HXT observations of Long Duration Events (LDEs) showed that the HXR emission (14-23 keV) is present for tens of minutes after flare maximum. Hence, some heating…

RHESSI Investigation of X-Ray Coronal Sources During Decay Phase of Solar Flares: I. Observations

Tomasz Mrozek, Zbigniew Koltun, Sylwester Kolomanski +1

We analyse the observational characteristics for a set of Long Duration Events (LDE) using Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI). Excellent energy resolutio…

Coronal mass ejections associated with LDE flares of slow rise phase

Urszula Bak-Steslicka, Sylwester Kolomanski, Tomasz Mrozek

It is well known, that there is temporal relationship between CMEs and associated flares. The duration of the acceleration phase is related to the duration of the rise phase of a f…

Energy Release During Slow Long Duration Flares Observed by RHESSI

Urszula Bak-Steslicka, Tomasz Mrozek, Sylwester Kolomanski

Slow Long Duration Events (SLDEs) are flares characterized by long duration of rising phase. In many such cases impulsive phase is weak with lack of typical short-lasting pulses. I…

Geometrical and Physical Properties of SXR Loop-Top Flare Kernels

P. Preś, S. Kołomański

We investigate how the geometrical and physical properties of soft X-ray flare kernels change with their altitude above the photosphere. We analyze limb flares well observed by {\e…
