%X 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.
