1. Project Neil Bone Initiated and coordinated by Richard Miles

2. Project Neil Bone Aim of the project Observe the selected asteroids at opposition and,also, while approaching and receding so as to record the opposition effect. Compare the effect between different asteroid classes.

5. Opposition effect

11. Differential photometry is employed to measure the asteroids brightness. 240 second guided exposures to acquire a good signal to noise ratio. MX916 camera @ f10 on a 235mm SCT ‘V’ filter Lodestar guide camera on a 90mm Maksutov

17. So what do we learn from all this: The opposition effect gives information regarding the surface regolith structure which may differ for different asteroid taxonomic classes. The phase curve contains information about its shape and rotation period. This in turn gives us an idea of whether it is a solid object or a rubble pile. It may show whether a companion is present i.e. whether it is a binary asteroid.
