Magnetic helicity and energy spectra of a solar active region
Hongqi Zhang, Axel Brandenburg, D. D. Sokoloff
We compute for the first time magnetic helicity and energy spectra of the solar active region NOAA 11158 during 11-15 February 2011 at 20^o southern heliographic latitude using obs…
Relations between strong high-frequency microwave bursts and proton events
V. Grechnev, N. Meshalkina, I. Chertok +1
Proceeding from close association between solar eruptions, flares, shock waves, and CMEs, we analyze relations between bursts at 35 GHz recorded with the Nobeyama Radio Polarimeter…
A Challenging Solar Eruptive Event of 18 November 2003 and the Causes of the 20 November Geomagnetic Superstorm. II. CMEs, Shock Waves, and Drifting Radio Bursts
V. V. Grechnev, A. M. Uralov, I. M. Chertok +7
We continue our study (Grechnev et al. (2013), doi:10.1007/s11207-013-0316-6; Paper I) on the 18 November 2003 geoffective event. To understand possible impact on geospace of coron…
Microwave Negative Bursts as Indications of Reconnection between Eruptive Filaments and Large-Scale Coronal Magnetic Environment
V. Grechnev, I. Kuzmenko, A. Uralov +2
Low-temperature plasma ejected in solar eruptions can screen active regions as well as quiet solar areas. Absorption phenomena can be observed in microwaves as 'negative bursts' an…
Filament eruption on 2010 October 21 from three viewpoints
Boris Filippov
A filament eruption on 2010 October 21 observed from three different viewpoints by the Solar Terrestrial Relations Observatory (STEREO) and the Solar Dynamic Observatory (SDO) is a…
Electron and proton acceleration during the first ground level enhancement of solar cycle 24
C. Li, Kazi A. Firoz, L. P. Sun +1
High-energy particles were recorded by near-Earth spacecraft and ground-based neutron monitors (NMs) on 2012 May 17. This event was the first ground level enhancement (GLE) of sola…
Study of Failed CME Core Associated with Asymmetric Filament Eruption
N. C. Joshi, A. K. Srivastava, B. Filippov +3
We present the multi-wavelength observations of asymmetric filament eruption, associated CME and coronal downflows on 2012 June 17-18 during 20:00-05:00 UT. We use SDO/AIA, STEREO-…
The origin of the helicity hemispheric sign rule reversals in the mean-field solar-type dynamo
V. V. Pipin, H. Zhang, D. D. Sokoloff +2
Observations of proxies of the magnetic helicity in the Sun over the past two solar cycles revealed reversals of the helicity hemispheric sign rule (negative in the North and posit…
A Challenging Solar Eruptive Event of 18 November 2003 and the Causes of the 20 November Geomagnetic Superstorm. I. Unusual History of an Eruptive Filament
V. V. Grechnev, A. M. Uralov, V. A. Slemzin +4
This is the first of four companion papers, which analyze a complex eruptive event of 18 November 2003 in AR 10501 and the causes of the largest Solar Cycle 23 geomagnetic storm on…
Electric Current Equilibrium in the Corona
Boris Filippov
A hyperbolic flux-tube configuration containing a null point below the flux rope is considered as a pre-eruptive state of coronal mass ejections that start simultaneously with flar…
