    CRD's SEVAN Network Expands to India's Jawaharlal Nehru University

    The ability to forecast space weather storms is vital for the security
    of space based electronic systems as well as the power grid delivering
    power to homes and industry. Armenia's Cosmic Ray Division is expanding
    its network to monitor and forecast space weather events.

    The Cosmic Ray Division (CRD) of Yerevan's Alikhanyan Physics Institute
    announced the expansion of its Space Environment Viewing and Analysis
    Network (SEVAN) into India. The SEVAN system consists of an
    internationally networked array of terrestrial cosmic ray detection
    systems at middle to low latitudes. Data from these installations is
    sent via internet to CRD's research center in Yerevan where it is
    analyzed and shared with international research partners throughout the
    world.

    The SEVAN network aims to improve fundamental research studying the
    mechanisms of cosmic ray particle acceleration in the vicinity of the
    sun and in other space environments to advance the Space Weather alert
    systems. New types of particle detectors, invented by CRD scientists and
    deployed within the SEVAN network, simultaneously measure changing
    fluxes of most species of secondary cosmic ray particles. Piecing this
    information together from world wide SEVAN installations, including
    precise timing information, allows scientists to predict dangerous solar
    radiation storms tens of minutes before their arrival from the sun.
    SEVAN's data also allows scientists to forecast damaging geomagnetic
    storms hours before their arrival. These storms, resulting from huge
    clouds of plasma traveling from the Sun towards the earth at speeds up
    to 4.5 million miles per hour, can cause extensive damage to
    communication systems, power grids, and pipelines.

    The first four SEVAN modules became operational at CRD's Aragats Space
    Environmental Center on the slopes of Armenia's Mount Aragats. In 2009
    additional SEVAN installations were deployed in Croatia and Bulgaria. In
    the fall of 2010 a SEVAN detector was installed in the Remote Sensing
    Applications Laboratory, School of Environmental Sciences, Jawaharlal
    Nehru University, New Delhi, India. This year's plans call for a SEVAN
    unit to be installed in Slovakia.

    Reliable forecasts of the major geomagnetic and radiation storms are of
    great importance due to the danger they pose to major space-based
    systems such as the Global Positioning System (GPS) and communication
    satellites. Radiation storms also pose a radiation hazard to astronauts
    in space and crews and passengers aboard aircraft. For further
