Discover how our star works by means of our presentations and observations: our heliostat projects a live image of the Sun onto a screen; a 90mm Coronado filter allows us to observe the sunspots and solar prominences with the L152 telescope; last but not least, the spectrmeter decomposes the light of the sun into a spectacular indoor rainbow, rich in scientific data. In bad weather, a conference on the Sun replaces the observation. The activity is thus held under any weather.

The Sun is displaying beautiful vigor in this recently taken photo at the Observatory. On its disk, sunspots and dark filaments as well as faculae (bright spots) underline the zones of strong activity whereas the “small” solar prominences (small, but bigger than the Earth!) are being detached from the surface of the Sun into the dark sky.
