To determine the characteristics of galactic and solar cosmic ray flux near Earth
by using neutron monitor measurements, the observation data are usually
submitted to analysis procedures involving extensive calculations and expert
knowledge. For space weather applications an equally valid method is desirable
that is straightforward, fast, and simple, to allow quasi-automatic data analysis

The latest GLE event (70th since 1942) was registered using neutron monitor
net on December 13, 2006. The response of neutron monitors shows a sharp
anisotropy of solar particle flux with direction close to the acceptance cone of
MEPhI muon hodoscopes (Moscow). Analysis of the enhancement in muon
ground level intensity measured by means of muon hodoscope URAGAN (MEPhI,
Moscow) is present

The new statistical method for search of weak signals of the various natures is
offered. This method is applied, when average value of a signal does not give
statistically significant excess over an average background of the device. The method
uses property of statistical distributions to increase number of the large
fluctuations in the mentioned above case. In result a noticeable change of

The neutron multiplicity changes on the neutron monitor in Barentsburg
(Spitsbergen) during the GLE December 13, 2006 has been studied. The
neutron monitor in Barentsburg was put into operation on April, 2003. In 2006
it has found the complete configuration 18-NM-64. The new data collecting
system based on a digital ADLINK 7233 card allows to register both pulses, and
intervals between t

Comparative analysis of the characteristics of relativistic solar cosmic rays (SCR)
in the two largest GLEs of 23 February 1956 and 20 January 2005 has been
performed. Using a modeling technique, the parameters of relativistic solar
protons (RSP) were obtained from ground-based observations by neutron
monitors (NM) and muon detectors. The two particle populations (components),
prompt (PC

The analysis of the GLE 13.12.2006 using the data of neutron monitors,
balloons, and modeling computations has been carried out. The event was
connected to the flare and appeared rather unexpected, as it occurred during
the ongoing phase of solar minimum. The characteristics of relativistic solar
protons were derived by modeling technique from the neutron monitors data.
The direct solar

Ground level enhancements due to solar flare protons have been recorded at
Sanae since 1971 by two neutron monitors with different sensitivities to primary
protons in the rigidity range < 1 GV to ~5 GV. Spectral indexes can be
determined from the enhancement ratios of the two detectors if their specific
yield functions (SYF) are known. The SYF obtained from latitude surveys and
primary c
