The Astrophysical JournalWe investigate the properties of two types of solar active regions: the small short-living groups (SSGs) and the large long-living groups (LLGs). The combined distribution of areas of active regions is bimodal. When deconvolved, the distributions of each

Relating near-Earth observations of an interplanetary coronal mass ejection to the conditions at its site of origin in the solar corona [PDF]
, 2005 A halo coronal mass ejection (CME) was detected on January 20, 2004. We use solar remote sensing data (SOHO, Culgoora) and near-Earth in situ data (Cluster) to identify the CME source event and show that it was a long duration flare in which a magnetic ...

The Origin of Sequential Chromospheric Brightenings
, 2017 Sequential chromospheric brightenings (SCBs) are often observed in the immediate vicinity of erupting flares and are associated with coronal mass ejections. Since their initial discovery in 2005, there have been several subsequent investigations of SCBs.

METHODOLOGY FOR VERIFYING THE CHIP AUTHENTICITY BASED ON DYNAMIC ENERGY CONSUMPTION ANALYSIS
Безопасность информационных технологийIn the conditions of restructuring and complication of logistic supply chains of EKB (Electronic Component Base) the risk of supplying counterfeit products increases significantly, which determines the relevance of the development of simple and cost ...

Current Helicity and Twist as Two Indicators of The Mirror Asymmetry of solar Magnetic Fields
, 2008 A comparison between the two tracers of magnetic field mirror asymmetry in solar active regions, twist and current helicity, is presented. It is shown that for individual active regions these tracers do not possess visible similarity while averaging by ...

, 2016 The century-long (1907-2007) Ca II K spectroheliograms from Kodaikanal Solar Observatory (KSO) are calibrated, processed and analysed in the present study to follow the evolution of bright on disc structures called plages, the possible representatives of

Helicity at Photospheric and Chromospheric Heights
, 2009 In the solar atmosphere the twist parameter $\alpha$ has the same sign as magnetic helicity. It has been observed using photospheric vector magnetograms that negative/positive helicity is dominant in the northern/southern hemisphere of the Sun ...

Evolution of Magnetic Helicity and Energy Spectra of Solar Active Regions
, 2016 We adopt an isotropic representation of the Fourier-transformed two-point correlation tensor of the magnetic field to estimate the magnetic energy and helicity spectra as well as current helicity spectra of two individual active regions (NOAA 11158 and ...
