SUMMARY:Guest Speaker - Peter Nosworthy (WSAAG)
LOCATION:: Zoom Online
DESCRIPTION:Stellar OccultationsObserving occultations of stars by solar system objects
such as asteroids, dwarf planets and planetary moons, is a powerful method
for measuring the sizes and shapes of these objects, refining our knowledg
e of their orbits, and detecting previously unknown objects in their vicini
ty such as rings and satellites. Using this technique, coordinated teams of
amateur observers can achieve results surpassing professional observatorie
s and even space based telescopes. It is a field in which amateurs can make
real contributions to science using only fairly basic equipment and some f
ree software tools. This has led to many collaborations between amateur and
professional astronomers. I will also describe how a colleague and I were
able to discover two asteroid moons using the occultation method, and how n
ew observers can get involved in the field.\n \nPeter NosworthyPeter has a
background in electronics and IT and has worked in the field of medical ele
ctronics (heart pacemakers and cochlear implants) and also as a software en
gineer in consumer electronics, stock market, and financial systems. He hol
ds a Bachelor of Applied Science (Computing) from UTS and an Electronics En
gineering Certificate from TAFE.\nPeter has been an amateur astronomer sinc
e the age of 12 and served as secretary and vice president of Northern Sydn
ey Astronomical Society (NSAS) before moving from Sydney to the darker skie
s of the Blue Mountains in 2012. After joining the Western Sydney Amateur A
stronomy Group (https://www.wsaag.org/) (WSAAG), where there was an active
group of occultation observers, he became interested in stellar occultation
s and built an observatory (Hazelbrook Observatory (http://hazelbrookobserv
atory.com/)) in his back yard in 2019. He has served on the committee of WS
AAG since 2016 and as president since 2022.\n

Observing occultations of stars by solar sy
stem objects such as asteroids, dwarf planets and planetary moons, is a pow
erful method for measuring the sizes and shapes of these objects, refining
our knowledge of their orbits, and detecting previously unknown objects in
their vicinity such as rings and satellites. Using this technique, coordina
ted teams of amateur observers can achieve results surpassing professional
observatories and even space based telescopes. It is a field in which amate
urs can make real contributions to science using only fairly basic equipmen
t and some free software tools. This has led to many collaborations between
amateur and professional astronomers. I will also describe how a colleague
and I were able to discover two asteroid moons using the occultation metho
d, and how new observers can get involved in the field.
