First chords observed across asteroid (7102) Neilbone

The European SODIS database (Stellar Occultation Data Input System) now lists two observations of chord timings across asteroid (7102) Neilbone. They were obtained from Switzerland on August 19 and France on September 7. This main-belt asteroid has a diameter of ~22 km, so it’s a challenge to obtain multi-chord observations of the same event.

These chords will help to confirm its diameter and will provide high-quality astrometry to refine its orbit.

Neil (1959 – 2009) was well-known in UK astronomy as a keen and knowledgeable observer and a publiciser of many branches of astronomy, and in particular aurorae, NLC and meteors – he served as BAA Meteor Section Director (1992 – 2009).
