Frequency Distribution of Acoustic Oscillation in the Solar Atmosphere During Flare Event

A. Wisniewska, E. Chmielewska, K. Radziszewski +2

We present a study of multi-wavelength observations, of a C 2.3 solar flare in Active Region NOAA 12353, observed on 2015 May 23, which reveal new properties of acoustic waves in t…

ALMA as a prominence thermometer: First observations

Petr Heinzel, Arkadiusz Berlicki, Miroslav Bárta +4

We present first prominence observations obtained with ALMA in Band 3 at the wavelength of 3 mm. High-resolution observations have been coaligned with the MSDP H data from Wrocl…

The depth and the vertical extent of the energy deposition layer in a medium-class solar flare

Krzysztof Radziszewski, Robert Falewicz, Pawel Rudawy

We analyze here variations of the position and the vertical extent of the energy deposition layer (EDL) inthe C1.6 GOES-class solar flare observed at 10:20 UT on 2012 September 10.…

A Search for High-Frequency Coronal Brightness Variations in the 21 August 2017 Total Solar Eclipse

P. Rudawy, K. Radziszewski, A. Berlicki +4

We report on a search for short-period intensity variations in the green-line FeXIV 530.3 nm emission from the solar corona during the 21 August 2017 total eclipse viewed from Idah…

Solar radio burst associated with the falling bright EUV blob

Marian Karlicky, Alena Zemanova, Jaroslav Dudik +1

At the beginning of the 4 November 2015 flare, in the 1300 -- 2000 MHz frequency range, we observed a very rare slowly positively drifting burst. We searched for associated phenome…

Time variations of observed H line profiles and precipitation depths of non-thermal electrons in a solar flare

R. Falewicz, K. Radziszewski, P. Rudawy +1

We compare time variations of the H and X-ray emissions observed during the pre-impulsive and impulsive phases of the C1.1-class solar flare on 21 June 2013 with those of plasma…

Variations of flaring kernel sizes in various parts of the H-alpha line profile

K. Radziszewski, P. Rudawy

We analyze the temporal variations of the sizes and emission intensities of thirtyone flaring kernels in various parts of the Hα line profile. We have found that the areas of all k…

Pencils of lines in generalized Laguerre spaces

Krzysztof Radziszewski

In the paper we characterize subspaces and pencils of lines of generalized (and multidimensional) Laguerre spaces and we consider definability of the structure of "conic" pencils i…

High time resolution observations of solar H-alpha flares - II. Search for signatures of electron beam heating

K. Radziszewski, P. Rudawy, K. J. H. Phillips

Aims. The H-alpha emission of solar flare kernels and associated hard X-ray (HXR) emission often show similar time variations but their light curves are shifted in time by energy t…
