Multi-Application Solar Telescope (MAST), a 50 cm diameter class telescope, was installed by AMOS on the Udaipur Solar Observatory's Island on Lake Fatehsagar in India. Despite its small size, the telescope is expected to be competitive with large and expensive projects around the world due to its versatility in terms of science goals and its demanding optomechanical and thermal specifications. In this article, we will discuss in detail regarding Multi Application Solar Telescope which will be helpful for UPSC exam preparation.

Multi Application Solar Telescope – Objectives

• The MAST's primary goal is to comprehend the evolution of the magnetic fields on the Sun and their relationship to solar activity.
  • This is significant because solar eruptions cause extreme space weather conditions that endanger humans by disrupting satellite communication, navigation, and other activities in space, as well as affecting the climate on Earth.
• MAST, in particular, aims to image solar active regions (groups of sunspots) in two different layers of the solar atmosphere, namely the photosphere and chromosphere.
• MAST aims to measure magnetic fields in these two layers as well.
• It will provide 3D images of solar activities such as solar flares and solar blasts and will be used to study seismic effects of solar flares.
• It will also be useful for studying other planetary movements during the day.

Significance of Udaipur Solar Observatory (USO)

• The USO, regarded as Asia's best solar observing site, is located on an island in the middle of Lake Fatehsagar in Udaipur, Rajasthan, where the sky conditions are ideal for solar observations.
• The large body of water that surrounds the telescopes reduces the amount of heat that reaches the surface layers.
• This reduces turbulence in the air mass, which improves image quality and visibility.
• The dome of the Multi Application Solar Telescope is a collapsible dome made of tensile fabric.
• The Udaipur site can boast of more than 250 days of continuous sunshine, allowing for proper observation of the sun during the day.
• To avoid wind turbulence, the building has no sharp edges. It is painted with a paint that has a high infrared emission capability to reduce heating from sunlight.
• It is divided into two floors: the telescope floor, which is visible during observations, and the instrument floor, which is air-conditioned to protect all of the electronics.
• The primary goal of obtaining high spatial and temporal resolution observations of solar photospheric and chromospheric activity is to comprehend the various dynamic phenomena that occur on the Sun's surface.
• Dr. Arvind Bhatnagar designed the observatory in 1976 after seeing the Solar Observatory at Big Bear Lake in Southern California.

Conclusion

By providing regular observations of the solar photosphere and chromosphere, MAST at USO promises to be an important ground-based facility that will complement the science objectives of current and upcoming ground-based and space-based missions.
