Udaipur Solar Observatory (USO)

Location: On an island of Fateh Sagar Lake
Built By: Dr. Arvind Bhatanagar
Built In: 1975

Udaipur Solar Observatory is considered as the best solar observing site in Asia. Situated on an island in the Fateh Sagar Lake, Solar Observatory of Udaipur is among the few in the world that are sited on an island. This observatory was designed as per the model of Solar Observatory at Big Bear Lake in Southern California. In 1975, Udaipur Solar Observatory was established by Dr. Arvind Bhatnagar under the Vedhashala Trust of Ahmedabad. The organization is basically affianced in Astrological activities. However, the observatory aspires to do research in modern science.

Udaipur Solar Observatory has become the perfect center to develop solar physics in India. Being surrounded by water, the island provides a favorable atmosphere for solar observations. As air turbulence is lesser on island then ground, sharp images of the sun can be acquired. Apart from this, other advantage of this observatory is that it is located in Rajasthan, which observes maximum number of cloudless days. All these factors add to quality of extracted images of the Sun.

The observatory comprises a range of telescopes that provide excellent quality of solar observations. The observatory is adding a new instrument by the name of 'Solar Vector Magnetograph' to its store-house. This instrument will play an important role in the future research program by determining the magnetic field of the active regions. It has been more than twenty-five years, since USO was established. The observatory has seen an entire solar cycle in the twenty-two years of its subsistence. Now, it is witnessing the next solar cycle.

The huge longitudinal gap between Australia and Spain is plugged by USO. Udaipur Solar Observatory also provides a connection for regular solar coverage in numerous International collaborative programs including GONG (Global Oscillations Network Group). Since 1981, the observatory has been under the control of the Physical Research Laboratory (Ahmedabad) for the Department of Space, Government of India.

Under GONG project, USO was numbered among the six observatories of the world that watch the sun for 24 hours. National Science Foundation of the United States that intends to study oscillations in the solar atmosphere has sponsored this project of GONG. Hence, USO is a site of national and international importance. If you are planning to visit this observatory, you have to take a boat ride to reach the observatory.
