The Meudon “solar tower” is commissioned

From the very beginning, the Meudon observatory was devoted to solar observations, and was extremely efficient, and in many cases original instruments such as the Deslandres spectro-heliograph were built. The last one is a large spectro-heliograph situated at the bottom of a 36-meter tower. Sunlight is channelled to it vertically using two steerable mirrors situated on the platform. This “solar tower” is the last of the French national instruments; those that followed were all built in the framework of international collaborations.
