We have studied the variation of the time profile of X-ray emission of solar flares that occurred during the second half of solar cycle 23 (SC 23) and for about the full solar cycle 24 (SC 24) (2002–2018). We define a new index, called the “ratio

We studied 2204 sympathetic flares detected by the GOES during 1975–2017. Sympathetic flares have nearby, or homogeneous, GOES classes. The secondary solar flare is just a mirror image of the primary solar flare of the sympathetic flare. It has two

The purpose of the present research is to study the latitudinal distribution and its asymmetry of solar flares during the period 2002–2017 and make a comparison between the studied data from two different satellites (GOES and RHESSI). We tried to b

Aims. We examine high time resolution dynamic spectra for fine structures in type II solar radio bursts Methods. We used data obtained with the (SAO) receiver of the Artemis-JLS (ARTEMIS-IV) solar radio spectrograph in the 450-270 MHz range at 10 ms

Aims. We examined the characteristics of isolated intermediate drift bursts (IMDs) and their morphologies on dynamic spectra, in particular the positioning of emission and absorption ridges and the repetition rate of fiber groups. These were compared
