Scientists gear up to study TSE effect on atmosphere, ground
Mumbai: As skygazers gear themselves up to witness the century`s longest Total Solar Eclipse (TSE) on Wednesday, scientists would be observing the Sun at subtler levels to study the rare celestial event and its effects.
Indian Institute of Geomagnetism (IIG), Indian Space
Research Organisation and Physical Research Laboratory have
elaborate arrangements to study the eclipse.
"Indian Institute of Geomagnetism for the first time
has set up experiments using high sensitivity digital
instruments at Dibrugarh, Ujjain and Bhagalpur, to study the
changes in the electrical conductivity of the ionosphere and
pressure waves in the atmosphere," its director Dr Archana
Bhattacharyya told agency.
This will give the scientific community an opportunity
to study the effects of TSE on electrical fields in the
ionosphere, on its electrical conductivity and hence on the
Its effect on propagation of radio waves in the
ionosphere and gravity waves in the atmosphere will also be
At IIG`s Allahabad centre, scientists have set up
experiments to look at radiowaves reflected from the
ionosphere using an Ionospheric Sounder (IONOSONDE) for
calculation of the density of electrons in the ionosphere.
"Greater effects of TSE are expected at Dibrugarh in
Assam, but the results in Allahabad, which is at the edge of
totality path may also be interesting," she said.
