27-day Variations of the Galactic Cosmic Ray Intensity and Anisotropy∗
We study the relationships of the 27-day variations of the galactic cosmic ray (GCR) intensity and anisotropy with the 27-day variations of the solar wind (SW) velocity, Wolf number (Rz) and interplanetary magnetic field (IMF) strength for different positive (A > 0) and negative (A < 0) polarity periods of the solar magnetic cycles based on the experimental data. We found that the long-lived ac...
متن کاملObservation of Anisotropy in the Galactic Cosmic Ray Arrival Directions at 400 Tev with Icecube
In this paper we report the first observation in the Southern hemisphere of an energy dependence in the Galactic cosmic ray anisotropy up to a few hundred TeV. This measurement was performed using cosmic ray induced muons recorded by the partially deployed IceCube observatory between May 2009 and May 2010. The data include a total of 33×10 muon events with a median angular resolution of ∼ 3◦ de...
متن کاملThe Large Scale Structure of the Galactic Magnetic Field and High Energy Cosmic Ray Anisotropy
The magnetic field in our Galaxy is not well known and is difficult to measure. A spiral regular field in the disk between the Galactic arms is favored by observations, however it is still controversial if the field reverses from arm to arm. The parity of the field across the Galactic plane is also not well established. In this letter we demonstrate that cosmic ray protons in the energy range 1...
متن کاملCosmic ray anisotropy along with interplanetary transients
Abstract The present work deals with the study of first three harmonics of low amplitude anisotropic wave trains of cosmic ray intensity over the period 1991-1994 for Deep River neutron monitoring station. It is observed that the diurnal time of maximum remains in the co-rotational direction; whereas, the time of maximum for both diurnal and semi-diurnal anisotropy has significantly shifted tow...
متن کاملCosmic Ray Anisotropy and Solar Activity
In this paper an attempt is made to study the occurrence of a large number of high amplitude anisotropic wave train events in cosmic ray intensity during 1981-1994 and to identify a possible correlation with solar activity using the hourly neutron monitor data of Deep River station. The diurnal time of maximum for both HAE as well as for all days is found to significantly shift towards an earli...
