Radio
Astronomy Centre
The Radio
Astronomy Centre is a joint
project of ASTE Council with
Cotton College, Guwahati and
has been functioning at the
department of Physics, Cotton
College with Prof. A. K. Goswami
as a Principal Co-ordinator
of the project. Under the project,
solar flux values in the S-band
around 2.8 GHz by a 2 metre
solar tracking Radio Telescope
is being recorded. The scientists,
researchers and students associated
with the centre have been participating
in a number of training, workshop
on basic astrophysics, radio
astronomy and mm wave propagation
organized and held at Eastern
Centre for Radio Astronomy (ECRA),
Kolkata to enhance knowledge
and capability. The present
system of data acquisition is
based on chart recorder, which
is slow and lack accuracy. The
system is being upgraded with
computer based data logging
techniques in the digital form.
This is the only facility of
solar radio astronomy in the
north east region of India with
ample scope of research and
application oriented activity.
The solar radio data recorded
by the centre are being analyzed
in consultation with the Eastern
Centre for Radio Astronomy,
Kolkata.
Data collection
in S-band done by the centre
would be used for study and
assessment of the following
phenomena.
Intensity
of ultra violet radio emission,
flair cycle variation, co-relation
between sunspot number and the
flair intensity, temperature
of the different layers of the
sun, intensity variation of
the recorded data depending
on atmospheric situation, absorption
co-efficient of atmosphere,
determination of time of corresponding
flair and its phases, determination
of intensity variation of the
flair during a year, detection
of solar burst , the co-relation
between solar flair and solar
burst.
