April 30, 2023 ALP Astronomy Experts Speaker Series featuring Dr. Daniel Green

Comets, the so called denizens and visitors from deep space, have inspired awe and even fear since ancient times. On April 30, 2023 (Sunday), at 9;30 a.m. Philippine Standard Time (April 29, Saturday, 9:30 p.m. EDT), please join us for an online talk on “A Brief Tutorial on Comets” by Daniel W. E. Green, Ph.D. , Director, Central Bureau for Astronomical Telegrams (CBAT}
Dr. Green will talk about what comets are, how they are becoming harder to define in terms of their physical nature, how they are discovered and named, some statistics regarding comets, and how amateur astronomers can contribute greatly to the science of comets.
Dr. Daniel Green has been the Director of the International Astronomical Union’s CBAT since 2000. The CBAT is responsible for the dissemination of information on transient astronomical events (i.e. comets) and various IAU news including the announcement of designations and names of various celestial objects. He is involved in research of small bodies of the solar system — particularly, comets and meteors but also minor planets. He collects and archives/publishes data on comets from observers around the world, and these data are published in the International Comet Quarterly.
Dr. Green is also a member of the International Astronomical Union’s 15-member Committee on Small Bodies Nomenclature, which approves names for comets and minor planets (including trans-Neptunian objects) and their satellites.
He obtained his Ph.D. in physics and astronomy from the University of Durham (U.K.).
