|SEISMIC STUDY OF SOLAR DYNAMICS|

|Helioseismic data during the last 17 years covering entire solar cycle 23
and the rising phase of solar cycle 24
have been used to study the rotation rate and its variation during the
solar cycle. The temporally varying component of the rotation rate
shows the well known bands of faster and slower than average rotation,
which migrate toward the equator at low latitude and toward the poles
at high latitudes. With the data covering two minima in solar activity
it is also possible to study the variation between the two solar cycles
and the behaviour during the peculiar minimum between solar cycles 23 and 24.
The helioseismic data have also given us some information about meridional
flow in the solar interior.
