PI. The Muon Team At present the muon realtime
data are based on observations from
multi-directional muon detectors located in 3
locations Nagoya - Japan São Martinho da Serra
- Brazil Hobart - Australia. Participating
institutions include the Shinshu University and
Nagoya University (Japan), University of Delaware
(USA), Southern Space Observatory of INPE and
Federal University of Santa Maria (Brazil),
Australian Antarctic Division and University of
Tasmania Hobart (Australia), and the University
of Kuwait (Kuwait).

MULTIDIRECTIONAL MUON DETECTOR - MMD
Ground-based detectors measure byproducts of the
interaction of primary cosmic rays (predominantly
protons and helium nuclei) with Earths atmosphere
Typical energy of primary 50 GeV for Galactic
cosmic rays (surface muon detector)

PHYSICAL MECHANISM CAUSING LOSS-CONE PRECURSORS
Cosmic Rays from Forbush Decrease region travel
to the upstream Earth with the speed of light
overtaking the shock ahead.
Intensity deficit confined in a cone
Loss-cones are typically visible 4-8 hours ahead
of shock arrival for shocks associates with major
geomagnetic storms. (Munakata et al., JGR, 105,
2000).

Cosmic ray anysotropy for March 26th (2008) and
it looks like ther is a small effect in the x
component of the anisotropy, exactly inside the
HSS (High Speed Stream) Private information
from Alisson Dal Lago and Marlos Rockenbach da
Silva
The loss cone has 3hr duration implying 45 deg
width, and it onsets first in the eastward
viewing channel, then vertical and westward, as
expected for an anisotropic depression of the
cosmic ray intensity.

THE SKY COVERAGE OF THE GLOBAL MUON DETECTOR
NETWORK (GMDN)
The GMDN geographic location (big star) of each
detector. The symbols (squares, triangles and
circles) shows the existing asymptotic viewing
direction of a particle incident to each
Multidirectional Muon Detector (MMD) with the
median primary rigidity, after correction for
geomagnetic bending of cosmic ray orbits. The
track through each symbol represents the spread
of viewing directions corresponding to the
central 80 of each multidirectional detectors
energy response.

FUTURE PLANS It is suggested the combination of
real time data and other information from NASAs
STEREO Mission with GMDN (Global Muon Detector
Network)
Development of a new methodology and technique
for applied international services to permit
Solar Heliosphere 3-D visualization with
accurate Space Weather forecasting. With
