Graham Appleby spent his working life on various projects at the Royal Greenwich Observatory in Herstmonceux and at Cambridge until its closure in 1998. At that time he transferred to the Natural Environment Research Council where he continues to work within the Space Geodesy Facility. He has a Mathematics BSc and an Aston University PhD in Satellite Laser Ranging. Graham has long been interested in the lunar occultation technique, having made a large number of visual observations and carried out various scientific analyses. He is currently involved in using the SLR system to make high-speed photoelectric observations of occultations for double star and stellar diameter determination.
