“…This anisotropy is fairly typical: it comprises either one region with increased or decreased flux, or two adjacent regions in one of which the flux is increased, and in the other it is decreased. Similar pictures are observed by the muon hodoscope URAGAN [Yashin et al, 2015].…”

“…The two adjacent regions with increased and decreased fluxes are observed by the URAGAN muon hodoscope. As an example in Figure 7, taken from [Yashin et al, 2015], we present the result of recovery of the cosmic ray flux at the boundary of Earth's magnetosphere as detected by the muon hodoscope from 08:00 to Figure 7. Cosmic ray flux at the boundary of Earth's magnetosphere as detected by the URAGAN muon hodoscope on May 12, 2014, averaged over the interval from 08:00 to 09:00 UT [Yashin et al, 2015].…”

The solar corona image in the center indicates the sunward direction, the cross on the left marks the direction of the interplanetary magnetic field line, the cross at the top is the direction of arrival of cosmic rays producing vertically incident muons.…”

We calculate the angular distribution of cosmic rays at a given point of the heliosphere under the assumption that the incoming flux from outer space is isotropic. The static magnetic field is shown to cause no anisotropy provided that the observation point is situated out of the trapped particle area. We consider a coronal ejection model in the form of a static cylinder with an axial homogeneous magnetic field inside. We calculate angular distribution samples in the trapped particle area (inside the cylinder) and show that there is a certain cone of directions with a reduced flux. For the same model with the moving cylinder, the angular distribution samples are calculated for different positions of the observation point outside the cylinder. Anisotropy of order of the ejection to light velocity ratio is shown to arise. The calculated samples are in qualitative agreement with URAGAN muon hodoscope data.

“…As described in the article (Yashin et al 2015a), the track parameters (two projection angles) are reconstructed in a real-time mode by means of the software which is based on the histogramming technique in each projection plane XZ and YZ and are stored in a two-dimensional data matrix over one-minute time interval. This data array is a "muon snapshot" of the upper hemisphere (limited by the detector aperture) acquired with a one-minute exposure.…”

Muon hodoscope URAGAN continuously detects the angular distribution of muons in a wide range of zenith angles and allows one to obtain information about variations, both in the intensity and in angular characteristics of the muon flux, caused by active processes in the heliosphere, the magnetosphere and atmosphere of the Earth. Various parameters of the muon flux anisotropy and methods of calculation of these parameters are discussed. Real-time processing of a continuous flow of multidimensional data from the muon hodoscope URAGAN is quite a challenge. In the article, methods of formation and primary analysis of the data, their processing in real time and obtaining time series of various parameters of integral counting rate and angular anisotropy of the muon flux, which are important for the physical analysis of modulation processes of cosmic rays in the heliosphere, are presented.

We address the problem of early diagnostics of geomagnetic storms based on the use of models of coordinates of movements of centers of solar coronal mass ejections (CME) and observations of their angular positions obtained from space monitoring systems. We propose a method for early diagnostics of geomagnetic storms, introduce a function to predict the distance between Earth and CME centers, and establish a decision-making procedure. We give an example of calculating the distance prediction function and implement the diagnostic decision-making procedure based on coordinate models and model observations of angular positions of CME centers. We determine the efficiency of the decision-making procedure for the algorithm for early diagnostics of geomagnetic storms.
