abstract = "A multi-directional telescope for detection of high-energy
galactic cosmic rays (GCRs) - muons was installed in 2001, through
an international cooperation between Brazil, Japan and USA, and
operated since then at the Southern Space Observatory -
SSO/CRS/INPE - MCT, (29S, 53W), Sao Martinho da Serra, RS, in the
south of Brazil. The telescope capability and sensitivity were
upgraded in 2005. The observations conducted by this telescope are
used for forecasting the arrival of the geomagnetic storm and
their interplanetary coronal mass ejection (ICME) drivers in the
near-earth geospace. The telescope measures high-energy GCRs by
detecting secondary muons produced from the hadronic interactions
of primary GCRs (mostly protons) with atmospheric nuclei. Since
muons have a relatively long life-time (about 2.2 microseconds for
muons at rest) and can reach the detector at ground level
preserving the incident direction of primary particles, the
telescope can measure the GCRs intensity in various directions
with a multidirectional detector at a single location, such as in
Brazil. ICMEs accompanied by a strong shock often forms a GCR
depleted region behind the shock known as a Forbush decrease. The
ICME arrival also causes a systematic variation in the GCR
streaming (i.e. the directional anisotropy of intensity). The
magnitude of the streaming is small (about 1 % or less), but its
variation is relevant. Some particles from this suppressed density
region traveling with about the speed of light leak into the
upstream region, much faster than the approaching shock, creating
the possibility of being observed, at earths surface, by a network
of global muon ground based multi-directional detectors telescopes
(GMDN), as precursory loss-cone anisotropy ahead of the upstream
region. Loss-cones are typically visible 4-10 hours ahead of shock
arrival for shocks associated with major geomagnetic storms. The
Brazilian muon detector telescope (MDT), at SSO, is part of the
MDTs global network GMDN on an international collaboration,
consisting of 10 institutions from 6 countries. ICMEs traveling in
interplanetary space and reaching the Earth - cause reduction in
cosmic ray counts at the earths surface by one to ten percent, and
can be detected sometimes as much as ten hours before their
arrival at Earth - with the GMDN, thus permitting accurate and
reliable Space Weather forecasting. The STEREO Mission - Solar
TErrestrial RElations Observatory, is the third mission in NASA's
Solar Terrestrial Probes program (STP). It is suggested that an
international cooperation should be established between the NASAs
STEREO and GMDN scientific community to permit the development of
a new methodology and technique to trace in 3-D the solar
heliosphere and the effects of solar structures traveling through
the solar wind to Earth, with the combination of real time data
and other information from the STEREO spacecrafts, (consisting of
two space-based observatories - one Ahead of Earth in its orbit,
and the other traveling Behind), with real time data generated by
the GMDN, (developed at Shinshu University, Japan,
http://adsabs.harvard.edu/abs/2008ApJ...681..693O). The two STEREO
spacecraft have been drifting apart (Ahead about 22 degrees per
year and Behind with the same rate in the opposite direction) from
Earth, and from each other. The STEREO spacecrafts A and B now
reached quadrature, 90 degrees separation, on January 24, 2009,
after two years in solar orbit since 2007,
(http://stereo.gsfc.nasa.gov/). The new NASAs STEREO and GMDN
methodology and technique for applied international services will
permit in the near future solar heliosphere 3-D visualization with
very accurate Space Weather forecasting.",
