| Notes | The Kodaikanal Solar Observatory Museum operates under strict institutional guidelines to ensure the integrity of its ongoing scientific research. Visitors are restricted to demarcated museum areas and coordinate-guided paths, with each visit limited to a maximum duration of 90 minutes. For organized educational groups and schools, the administration requires a formal request via their official portal at least 15 days in advance. Notably, the facility offers a night sky observatory for public viewing during clear weather, typically on Thursday and Friday nights, though this is subject to institutional approval. As a specialized resource, the museum also provides "Educational Visit Certificates" for recognized academic institutions upon completion of their tour. |
