• Specola Solare Ticinese

    The Specola Solare Ticinese, situated in Locarno Monti, is the oldest astronomical observatory open to the public in the Canton of Ticino. Its roots go back to the mid-20th century, and indeed even earlier: when, around 1850, Rudolf Wolf embarked on an ambitious research project to rigorously reconstruct the newly discovered solar cycle. The result is nearly 180 years of observations carried out using a codified method – an ancient yet still valid approach used throughout the world. In the meantime, there have been two world wars, revolutions, and major cultural and social transformations. But the Sun has been shining for 5 billion years and will continue to illuminate our planet for just as long. The Specola Solare Ticinese does not aspire to continue studying our star until its very end. However, as long as there are people on Earth who are curious about the universe, the Specola hopes to be a place where knowledge of the Sun can continue to grow.

    Please note! Specola Solare Ticinese does not deal with weather phenomena.

  • Specola Solare Ticinese has suspended all science outreach activities with effect from 1 May 2025 due to major refurbishment work on the building. Scientific research activities, however, are continuing as normal. The works will be completed no earlier than the summer of 2026, after which all activities will resume as normal. We look forward to welcoming visitors once again when the works are complete.

  • A leading figure in both professional and amateur astronomy in Ticino, former director of Specola Solare Ticinese, with 64 years’ experience in solar observation, and heir to the Zurich tradition which, over 170 years of research and measurements, from Wolf, Wolfer, Brunner and Waldmeier, led right up to him; one of the founders and then long-standing president of the Ticino Astronomical Society, Sergio Cortesi is no longer with us. We shall miss him terribly.

  • The ETH Zurich library has published an interesting article on research into solar physics carried out in association with the university, which also highlights the role of the work carried out at Specola Solare Ticinese.
