Abstract:Synoptic observations of the Sun are very important to understand the long term behavior of
the solar activity cycle. Our current understanding solar magnetic cycle is rather in its infancy,
as can be inferred from our very poor prediction for the strength of solar cycle 24, based on
various dynamo models. Solar magnetism is at the heart of all solar activity and therefore it is
important to understand what parameters govern the magnetic cycle in the Sun. An important
parameter that is realized more recently is the internal dynamics, i.e., profile of solar internal
rotation and nature of large scale meridional flows. Therefore, it is important to study the solar
interior by making use of helioseismology. Ground based helioseismology networks such as
GONG are now quite few decades old and its possible failure poses risk to the continuity of
solar oscillation data. Hence, a next generation of synoptic network SPRING is being proposed
and is currently under design study. We will present science requirements and the details of
the SPRING network.
