Analysis of 22000 Crater Timing observations made over 170 years

Dave Herald & Roger Sinnott

CAS

Over 22,00 crater timing observations made over 170 years have been collected, archived at Vizier, and analysed. Many NACAA participants will have contributed to the observation dataset, by way of their participation in the program run by the late Byron Soulsby. The presentation will provide an overview of the results of the analysis.

This presentation is made in honour of Byron Soulsby (a past Convenor of NACAA) and Joe Ashbrook of S&T, who were instrumental in promoting crater timing observations.

Dave has a long-term interest in astronomy, was a co-author of the Herald-Bobroff Astroatlas, author of the occultation software OCCULT, and a recipient of the Berenice and Arthur Page medallion.
