The Udaipur Solar Observatory was built following the model of the Solar Observatory at Big Bear Lake in Southern California. Located on an island in Fateh Sagar, the observatory was built in the year 1976 by Dr. Arvind Bhatnagar.Owing to the location of the observatory amidst a large mass of water, air turbulence that occurs due to the ground getting heated by the suns rays gets reduced. As a result of this effect, the image quality and accuracy get significantly improved.High-resolution equipment for solar chromospheres, magnetic field, velocity and spectral observations are there in the observatory. This equipment permits studies pertaining to solar flares, mass ejections and the evolution of solar active regions.Managed by the Physical Research Laboratory, Ahmedabad, for the Department of Space, the observatory fills the large longitudinal gap between Australia and Spain.
