Chasing the dragon

If the Roy­al Obser­va­to­ry at Green­wich has a roy­al star, it has to be Gam­ma Dra­co­nis, also known as Eltanin, “the drag­on’s head.” Eltanin is not an espe­cial­ly bright star, in a con­stel­la­tion, Dra­co, the Drag­on, with­out any bright stars. But it does have a claim to local fame: It pass­es direct­ly over­head Lon­don once each day.
