Termination shock as a source of unusual solar radio bursts

Valery Fomichev, Gennady Chernov

Using centimeter wave and decimeter wave solar radio spectral observations of the flares of November 18, 2003 and September 12, 2004, we have discussed two type II like bursts at t…

Shape of solar cycles and mid-term solar activity oscillations

D. D. Sokoloff, A. S. Shibalova, V. N. Obridko +1

The evolution of the solar activity comprises, apart from the well-known 11-year cycle, various temporal scales ranging from months up to the secondary cycles known as mid-term osc…

Estimates of current helicity and tilt of solar active regions and Joy's law

K. Kuzanyan, N. Kleeorin, I. Rogachevskii +2

The tilt angle, current helicity and twist of solar magnetic fields can be observed in solar active regions. We carried out estimates of these parameters by two ways. Firstly, we c…

Wavelet analysis of the long-term activity of V833 Tau

R. Stepanov, N. I. Bondar', M. M. Katsova +2

The bulk of available stellar activity observations is frequently checked for the manifestation of signs in comparison with the known characteristic of solar magnetic modulation. T…

On the Relationship Between Transit Time of ICMEs and Strength of the Initiated Geomagnetic Storms

I. M. Chertok

More than 140 isolated non-recurrent geomagnetic storms (GMSs) of various intensities from extreme to weak are considered, which are reliably identified with solar eruptive sources…

Failed prominence eruptions near 24 cycle maximum

B. Filippov

We analyze 16 failed filament eruptions observed near 24 solar cycle maximum from May 2013 to July 2014. No significant rotation of filament spines is observed during the ascent in…

Cycles on the Solar-Type Stars and Cooler Dwarfs

N. I. Bondar, M. M. Katsova, M. A. Livshits

Features of the development of activity cycles in the solar-type stars and fast-rotating cool dwarfs have been considered for 65 stars observed in some decades. Cycles with duratio…

The origin and effect of hemispheric helicity imbalance in solar dynamo

S. Yang, V. V. Pipin, D. D. Sokoloff +2

In this paper we study the effects of hemispheric imbalance of magnetic helicity density on breaking the equatorial reflection symmetry of the dynamo generated large-scale magnetic…

Solar Total Eclipse of 21 August 2017: Study of the Inner Corona Dynamical Events Leading to a CME

Boris Filippov, Serge Koutchmy, Nicolas Lefaudeux

Total solar eclipse (TSE) coronal large and small scale events were reported in the historical literature but a definite synoptic coverage was missing for studying a relationship w…

Alternative Models of Zebra Patterns in the Event on June 21, 2011

L. V. Yasnov, G. P. Chernov

The analysis of the spectral characteristics of the burst radio emission on June 21, 2011 was carried out on the basis of an improved methodology for determining harmonic numbers f…

Cyclic variations in the main components of the solar large-scale magnetic field

V. N. Obridko, D. D. Sokoloff, B. D. Shelting +2

We considered variations the dipole and the quadrupole components of the solar large-scale magnetic field. Both the axial and the equatorial dipoles exhibit a systematic decrease i…

The mean tilt of sunspot bipolar regions: theory, simulations and comparison with observations

N. Kleeorin, N. Safiullin, K. Kuzanyan +3

A theory of the mean tilt of sunspot bipolar regions (the angle between a line connecting the leading and following sunspots and the solar equator) is developed. A mechanism of for…
