Introduction

Nestled amidst the serene waters of Fateh Sagar Lake in Udaipur, the Udaipur Solar Observatory (USO) stands as a beacon of scientific inquiry and solar research in India. Often referred to as the best solar observing site in Asia, this observatory is a significant landmark for both tourists and scientific communities. It provides unparalleled opportunities to study the sun and its various phenomena in a setting that is as picturesque as it is scientifically advanced.

Historical Background

Origin and Significance

The Udaipur Solar Observatory was established in 1976 by Dr. Arvind Bhatnagar, inspired by the design of the Solar Observatory at Big Bear Lake in Southern California. The choice of location on an island in Fateh Sagar Lake was strategic, leveraging the calm waters to reduce air turbulence, thus enhancing the quality of solar observations. The observatory was initially managed by the Vedshala Trust of Ahmedabad, but in 1981, it was taken over by the Physical Research Laboratory (PRL) in Ahmedabad under the Department of Space, Government of India.

Important Milestones

• 1976: Establishment of the observatory by Dr. Arvind Bhatnagar.
• 1981: Management transferred to the Physical Research Laboratory.
• 2007: Development and installation of the Scale Vector Magnetograph.
• 2015: Introduction of the Multi-Application Solar Telescope (MAST), one of the largest telescopes in India.
