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
