The Indian Astronomical Observatory (IAO) located at Hanle near Leh in Ladakh is becoming one of the promising observatory sites globally, said a recent study.
  • This is due to its advantages of more clear nights, minimal light pollution, background aerosol concentration, extremely dry atmospheric condition, and uninterrupted by monsoon.
  • night observations at IAO-Hanle from 2m-Himalayan Chandra Telescope (HCT) are possible throughout the year without any interruption due to monsoons.
  • Researchers from India and their collaborators carried out a detailed study of the night time cloud cover fraction over 8 high altitude observatories, including three in India.
  • They analysed datasets for the Indian Astronomical Observatory (IAO) in Hanle and Merak (Ladakh), and Devasthal (Nainital) in India.
  • Hence both statements are correct.

Location of Indian Astronomical Observatory (IAO)
The Indian Astronomical Observatory (IAO) is indeed located at Hanle, near Leh in the Union Territory of Ladakh.
- Geographical Significance: This location is strategically chosen due to its high altitude and clear skies, making it an ideal site for astronomical observations.
Continuous Night Observations
The second statement regarding night observations at the IAO-Hanle is also correct.
- Weather Conditions: Hanle experiences minimal cloud cover and is not affected by the monsoon season like other parts of India. This allows for uninterrupted observations throughout the year.
- Telescope Capacity: The 2m Himalayan Chandra Telescope (HCT) can operate effectively due to these favorable conditions, facilitating extensive astronomical research.
Conclusion
Both statements about the Indian Astronomical Observatory are accurate:
- Statement 1: Correct—IAO is located in Hanle, near Leh, Ladakh.
- Statement 2: Correct—Night observations can indeed be conducted year-round without interruption due to monsoons.
Thus, the correct answer is option 'C': Both 1 and 2.
