Statistical Studies of Velocity Patterns Inside the Supergranular Cells
J. Singh
We are interested in statistical studies of velocity
pattern inside the supergranular cells to investigate the relation-
ship between
- Velocity pattern and cell size
- Velocity pattern and lifetime of the cell
- Velocity and magnetic field at the cell boundary, by using calcium
K emission at the boundary as proxy for magnetic field and
- change in velocity pattern with solar cycle phase if any.
For this we need good quality velocitygrams obtained conti-
nuously with an approximate interval of 15-30 minutes for about 3-4
days without much gap in the data. If continuous data is not possible
we can still use the data to find answer to 2 questions out of four
listed above.We shall use our own calcium K line spectroheliograms
obtained at KODAIKANAL required as proxy to magnetic fields . It will
be better if we can get the data of 3-4 days every year upto maximum
phase of the solar cycle.
We are not interested in particular date because of statistical nature
of this study.
