Airy verses a Cooke


The occultation of Aldebaran in 1867 was observed by Mr Airy who remarked that the star did not come out bright instantaneously but was 38 seconds regaining its full light.

Whereas Mr Joynson with his 3.5 inch Thomas Cooke & Sons telescope described the star as sliding on the Moon’s disk at the immersion but re appearing instantaneously.
