Quasi-Periodic Pulsations in an M-Class Solar Flare
نویسندگان
چکیده
We have studied the quasi-periodic pulsations (QPPs) of M2.3 flare that occurred in active region NOAA 12172 on 23 September 2014. Through fast Fourier transform (FFT) method, we decompose light curves into fast- and slowly-varying components, cut-off threshold is 100 s. find QPPs a period 40 s at soft X-ray (SXR), hard (HXR), radio ultraviolet (UV). Based Atmospheric Imaging Assembly (AIA) Solar Dynamics Observatory (SDO), take place same time interval as ribbon separation, seem to originate from ribbons. Our observations tend support mechanism periodic nonthermal electron injection during eruption.

Broadband Quasi-Periodic Radio and X-ray Pulsations in a Solar Flare
We describe microwave and hard X-ray observations of strong quasiperiodic pulsations from the GOES X1.3 solar flare on 15 June 2003. The radio observations were made jointly by the Owens Valley Solar Array (OVSA), the Nobeyama Polarimeter (NoRP), and the Nobeyama Radioheliograph (NoRH). Hard X-ray observations were made by the Ramaty High Energy Solar Spectroscopic Imager (RHESSI). Using Fourie...
متن کاملIssn 1845–8319 Multiperiodicity in Quasi-periodic Pulsations of Flare Hard X-rays: a Case Study
We present a case study of the solar flare (SOL2001-10-02T17:31) that showed quasi-periodic pulsations (QPPs) in hard X-rays with two simultaneously excited periods, P1 = 26 − 31 s and P2 = 110 s. Complete evolution of the flare recorded by the Yohkoh telescopes, together with the patrol SOHO/EIT images, allowed us to identify magnetic structures responsible for particular periods and to propos...
متن کاملSolar Flare M-class Prediction Using Artificial Intelligence Techniques
Currently, astronomical data have increased in terms of volume and complexity. To bring out the information in order to analyze and predict, the artificial intelligence techniques are required. This paper aims to apply artificial intelligence techniques to predict M-class solar flare. Artificial neural network, support vector machine and naïve bayes techniques are compared to define the best pr...
متن کاملA multi-periodic oscillatory event in a solar flare
Aims. Ratios of different significant periods found in the light curves of a solar flare exhibiting quasi-periodic pulsations (QPP) are used to distinguish between the possible physical mechanisms responsible for such periodic behaviour. Methods. Time series data of the flaring event of 2002 July 3, observed via the Nobeyama Radioheliograph, Nobeyama Radiopolarimeters, and the RHESSI satellite,...
متن کاملSunspot Rotation and the M-class Flare in Solar Active Region NOAA 11158
In this paper, we measure the rotation of a sunspot in solar active region NOAA 11158 (Solar Target Identifier SOL2011-02-15) that was associated with an M-class flare. The flare occurred when the rotation rate of the sunspot reached its maximum. We further calculate the energy in the corona produced by the sunspot rotation. The energy accumulated in the corona before the flare reached 5.5× 10 ...
