Width of Radio-Loud and Radio-Quiet CMEs [PDF]
, 2007 In the present paper we report on the difference in angular sizes between radio-loud and radio-quiet CMEs. For this purpose we compiled these two samples of events using Wind/WAVES and SOHO/LASCO observations obtained during 1996-2005. It is shown that the radio-loud CMEs are almost two times wider than the radio-quiet CMEs (considering expanding parts

Dependence of the F2-layer critical frequency median at midlatitudes on geomagnetic activity
Solar-Terrestrial Physics, 2017 We put forward a method of separating the geomagnetic activity contribution to the F2-layer critical frequency median, foF2med, at middle latitudes. It is based on the analysis of foF2, which is the ratio foF2med/foF2q in percent, where foF2q is the F2 ...

Analysis of the ionospheric parameter dynamics on the basis of a generalized multicomponent model
E3S Web of Conferences, 2018 In the present paper, we have carried out an analysis of the ionospheric critical frequency data of the F2 layer during strong magnetic storms in 2017-2018. The ionospheric data of Paratunka (IKIR FEB RAS, Kamchatka, 53.0 N, 158.7 E), Wakkanai (Japan, 45.

Barometric effect of neutron component of cosmic rays at Antarctic station «Mirny»
Solar-Terrestrial Physics, 2016 The barometric effect of cosmic ray neutron component was estimated on the example of the Antarctic station Mirny. We used hourly data from continuous monitoring of neutron component and data from a local weather station for 2007–2014.

Nonlinear Absorption of Radio Waves in a Noncollinear Antiferromagnet [PDF]
JETP Lett. 99 (4), 229 (2014), 2015 The nonlinear absorption of radio waves (200 - 800 MHz) in a noncollinear cubic antiferromagnet Mn3Al2Ge3O12 in an external magnetic field H || [001] has been studied in the temperature range of 1.2 - 4.2 K. We attribute the observed dissipation of the electromagnetic energy to the parametric excitation of inhomogeneous surface waves at the boundaries ...

Are Cluster Radio Relics Revived Fossil Radio Cocoons? [PDF]
arXiv, 2000 A new model for the, so called, `cluster radio relics' is presented (Ensslin & Gopal-Krishna 2000). Fossil radio cocoons, resulting from the former activity of radio galaxies, should contain a low energy relativistic electron population and magnetic fields.

Quiet time F2-layer disturbances: seasonal variations of the occurrence in the daytime sector [PDF]
Annales Geophysicae, 2009 Earlier revealed seasonal/latitudinal variations of the occurrence for positive and negative F2-layer Q-disturbances have been interpreted in the framework of the present-day concept of the thermosphere-ionosphere interaction. The basic process is the
