Overview

Solar Physics is one of the major areas of research at the Physical Research Laboratory (PRL). The dedicated research group in solar physics is based at the Udaipur Solar Observatory (USO) in Udaipur. The well-equipped ground-based solar observation facility at Udaipur is known globally for highest quality observational solar research. The major science goals of solar physics research group are to understand the physics of solar oscillations, evolution of sunspots, sunspot fine structure, MHD processes in the solar atmosphere, coronal heating, solar eruptions and space weather prediction. Solar research group extensively utilizes data obtained from both ground-based and space-based instruments together with numerical simulations to address key research problems in solar physics. Scientists are also involved in design, development, and operation of various ground-based and space-based instruments.

USO also conducts various outreach activities for the school students. More details can be find at USO Outreach Programme.
