A typical day for Professor David
The Dome
It is early in the morning at the Royal Observatory in Uccle, but already the scientists are at work and the dome is open. The sky is clear and the nice weather will allow them to observe all quietly their favourite subject: the Sun. Observations are always of better quality in the morning or at true noon when the Sun is at the culmination point in the sky. Indeed, in the morning, the pollution does not yet contaminate the atmosphere above Brussels and the culmination point is the point where the solar rays cross our atmosphere the most directly. This allows then the astronomers to avoid a major part of the interferences due to different atmospheric layers that surround the terrestrial globe. The dome is rotary, giving thus the possibility to observe in all directions and at any time of the day.
