Friday 16th March 2018 - Jacquie Milner - Space Weather: Part 2 - Geomagnetic Storms

8pm Friday 16th March we have our Jacquie Milner continuing her beginners talk introduction to space weather, this time on "Geomagnetic Storms".

Last month we focused on the Sun and solar activity, but this month is all about what happens when that solar output reaches Earth. While aurorae are the most obvious effect of increased solar activity, there are other less obvious (and more unwelcome) effects that occur, ones that have important impacts on our increasingly electrical-reliant society. We will also take a look back in history to the Carrington Event of 1859, and why it’s been rescued from an interesting footnote in astronomical history to be held aloft as a portent of apocalyptic doom in recent times.

Members' Night is on every Friday night commencing at 8PM sharp (doors open 7:30PM). Guests of members are always welcome.


Please consider the neighbours and drive in and out quietly using low beam only, or better still, parking lights.


Please note: MBO will always be closed on days of Severe, Extreme and Code Red fire ratings, please see the CFA website for up-to-date information.

Friday 9th March 2018 - Dr Duane Hamacher - Variable stars: their history and observation

8pm Friday 9th March we have our own Dr Duane Hamacher talking to us about "Variable stars: their history and observation":

Variable stars are one of the most popular targets of amateur astronomical research. But what are variable stars? What is the history of variable star observations? From ancient Egypt and Aboriginal Australia to modern scientific observations, variable stars continue to fascinate observers - both amateur and professional. What are the various types of variable stars? But what can we actually see with the naked eye? Do you think you could identify the different types of variable stars from their light curves alone? This talk will explore these topics, teach you how to identify basic variable star types, and how to distinguish them from transiting exoplanets.

Dr Duane Hamacher is an MBO member, Senior Research Fellow at Monash University, and a lifelong astronomy advocate. After earning a degree in physics in the US, he completed a Masters degree by research in astrophysics at UNSW studying variable stars and transiting exoplanets. He then earned a PhD studying Australian Indigenous astronomical knowledge. Much of his work has been on the subject of variable stars - from observational searches for exoplanets at Siding Spring Observatory, to descriptions of pulsating variables and supernovae in Indigenous traditions.

Members' Night is on every Friday night commencing at 8PM sharp (doors open at 7:45PM this Friday as there is a closed committee meeting beforehand). Guests of members are always welcome. Contributions of food to share for supper are always gratefully received and demolished! :-)

Friday 2nd March 2018 - Sky For The Month with Perry Vlahos

At 8pm this coming Friday 2nd March we have Perry Vlahos for our members night talking to us about the coming months night sky.

March is one of the best months of the year to be observing the heavens – nights are still balmy, the big bright constellations of summer like Orion, Canis Major and Gemini are still around and the southern sky is also just coming to life with parts of the huge old constellation Argo getting close to culmination, with support from Crux and Centaurus.  It’s a great time to be observing galactic clusters like M35, the Beehive, M46 and M47, M41 in the northern sky, whilst in the southern sky there’s NGC2516, the Pyramid Cluster (NGC3293), the Pin Cushion (NGC3532), the Five of Diamonds (IC2602) and the rising of the Jewel Box. Perry will show you where they are in the sky and what to look out for when you’re observing them through a telescope. All this plus a delicious supper that follows the talk, and observing through MBO telescopes. See you there.

Members' Night is on every Friday night commencing at 8PM sharp (doors open 7:30PM). Guests of members are always welcome. Contributions of food to share for supper are always gratefully received and demolished! :-)

Friday 23rd February 2018 - Jacquie Milner - Space Weather: Part 1- the Solar Cycle

8pm Friday 23rd February we have our own Jacquie Milner giving a beginners talk introduction called "Space Weather: Part 1- the Solar Cycle".

Our second attempt to get Beginner’s Nights kicked off for 2018 will be to take a look at the Sun and its cyclical activity. Besides sunshine it spits other types of electromagnetic energy at us at times, some benign and some more troublesome. Down here on the surface of the Earth, protected by the atmosphere and the Earth’s magnetic field, we don’t notice it so much, but if we are to become a spacefaring race this kind of knowledge becomes much more vital. Come along and learn about the solar cycle, sun spots, coronal holes, solar flares and coronal mass ejections.

Members' Night is on every Friday night commencing at 8PM sharp (doors open 7:30PM). Guests of members are always welcome.
