21.01.2022 Hey guys just an update about camp this weekend I have spoken to Glenngarry Boys Brigade and they are business as usual. They have had a big cleanup in anticipation of our weekend out there. If you have any questions please feel free to contact me personally. There is water in the dam and clear skies are expected. See you all there. Rhondda.
20.01.2022 I would like to thank all our members who joined us last night on our first Zoom Society Meeting. It was great catching up with YOU all and was a great success. Thank you. We will be having our AGM on the 21st July via Zoom. Only financial members are able to vote. Thank you for your continued support. Heres to a better 2021.
20.01.2022 CANOPUS - HR2326 Sirius with its -1.47 magnitude is the brightest star we see in the night sky. The second brightest star is Canopus, and has an apparent magnitude of -0.72. This star is located in the constellation Carina, and is 309 light-years from Earth. From Earth it is easily seen as a white-yellow dominant star. Because of its position and brightness, Canopus is a star that spacecraft (during flight) often use for orientation. The brilliant giant Canopus is a little-kn...own type G supergiant, with an estimated surface temperature of 7280 K. After consuming hydrogen in the nucleus - Canopus has gone through a red giant phase, and is now in the phase of burning helium in the nucleus. The star has a very warm corona, which is ten times warmer than the Suns. This corona can be seen on X-rays, and radio waves. Scientists have also noticed large sources of X-rays that are most likely emitted from that corona. Physically, Canopus is 66 times larger than the Sun, and its mass is 8 to 9 times larger than the Sun. With this magnitude, Canopus is located on the border between medium and massive stars. This mass is not enough for Canopus to explode as a supernova, and with that this star will never end up as a white dwarf. How far is it? The New Horizons spacecraft was launched in 2006, and in 2015 it arrived near Pluto. It would fly to the Canopus star approximately 6.3 million years ago. See more
19.01.2022 The Lyrid meteor shower is occurring this week, and will peak on the 22nd and 23rd of April. Best observing times are between midnight and dawn. No equipment required, just a comfy chair or a picnic blanket to lay down on. and a hot drink and snacks.
17.01.2022 Good morning everyone. Welcome to our new committee. AGM last night went well couple of people were missed. Welcome to our new member John.
13.01.2022 One to mark-down in your diary (phone ... whatever) -- a once in a lifetime astronomical event (so its almost certain to be bucketing down). No doubt all of you have been watching Jupiter and Saturn fairly close to each other in the evening sky over the past few months. They are about to close considerably. On 21st December 2020, just after sunset (about 20 degrees above the western horizon) they will reach a very close conjunction just 6.5 arc-minutes apart! How many... of you astronomical grey-beards out there can say: Ive seen Jupiter and Saturn in the same eyepiece field? Jupiter catches-up with Saturn about every 19-odd years, but they are very rarely *this* close at conjunction (because of the tilts of both their and our orbit around the Sun). This is the closest conjunction between Jupiter and Saturn since 1623. There wont be another one this close until 2080. Dont miss it! See more

11.01.2022 Hi everyone I just want to let you all know we had our visit to the planetarium today. It was a fantastic show if you can get out and see it. We had 10 members attend today and we are going to try and continue the visits there over the next few months when the shows are changed. We had a great arvo.

11.01.2022 Spread the word and look to the skies: Tell us what you can see on the longest night, help us map Australias light pollution, and set a world record. Scientists are asking all Australians to step outside on the longest, darkest night of the year to help them measure light pollution around the country.... Could you please share the following with your friends and colleagues? The Australasian Dark Sky Alliance is asking people to join them this Sunday on Australias longest night to help researchers create a map of Australias darkest skies, and learn about light pollution and its effect on people, animals, and astronomy. Together, our observations will map how light pollution varies across Australias cities and regions, and make a GUINNESS WORLD RECORDS attempt for Most users to take an online environmental sustainability lesson in 24 hours, says Marnie Ogg, ADSAs CEO and founder. The project is supported by the Australian Government Department of Agriculture, Water and the Environment, which has produced The National Light Pollution Guidelines for Wildlife. Other supporters include ASTRO 3D, AstroNZ, Bintel, ICRAR, Globe at Night, Unihedron, ANU, the International Dark Sky Alliance, Laing Simmons & Young, Waiheke Island Dark Sky Park and Dark Sky Traveller. Look out for tweets from @DarkSkyAlliance, retweet them, and share your own thoughts, support and pics on the night using the hashtags #LightPollution and #DarkSky. And sign up to take part on the night at worldrecordlight.thinkific.com. Please feel free to pass this information on to your friends and colleagues we need dark sky observations from the city, country, suburbs, outback and everywhere in between.

Please book your place now for the weekend of the 13th November. Members and family only please.
04.01.2022 The world is a little strange right now. Normalcy has been a bit uprooted and many are wondering what to do in this time when so much is closed or postponed. But you know what isnt closed? The stars. Every night they shine brightly above us no matter where you might be. Take a breath, step out into the night air and look up. Just so many generation before us we look up and wonder. Regardless of what is occurring the stars above are always there. Be it with your naked eye, binoculars or a telescope go out and explore. Come and join us tonight at Montgomery Park, Wellington Point for our viewing night. ALL welcome

02.01.2022 To Our Valued Glengarry Customers, The Boys Brigade Queensland Ltd wishes to advise you of its decision to suspend operations of the Glengarry Education Centre in light of concern around current circumstances relating to COVID-19 (Coronavirus). Our concern is for the health and welfare of those intending to hire our facilities, our staff, and the wider Mount Tarampa community. Our Board of Directors is conscious of the impact of such a decision, but believes it is import...ant to respond quickly to a rapidly changing, serious community health crisis. All bookings at the campsite between 18 March 2020 and 31 May 2020, have been cancelled. Deposits already paid on these bookings will be held against future bookings. This initial suspension of operations will be reviewed in the lead up to 31 May 2020 with further decisions to be made about re-opening or a continuation of the closure. Please be assured that we intend to resume normal operations as soon as COVID-19 is no longer a threat. We thank you for your ongoing support and cooperation at this difficult time and we apologise for the unavoidable inconvenience. We continue to pray for Gods leading and protection and we know He will remain with us all at this challenging time. Ian Walters The Boys Brigade Qld roperty Director / Campsite Administartor
01.01.2022 WHY THE STARS ARE DIFFERENT COLORS When we look at the clear starry sky, the first thing we notice is that some stars are better seen than others. With the naked eye we can see up to the sixth magnitude, and then notice that the stars are of different colors. There are shades, but the stars have three basic colors: red, yellow, and blue. Red stars are the coldest and blue or white are the warmest. We can also determine the age of a star by its color. Young stars are hot blue ...or white, and old ones are relatively cool and red. The color of a star depends on the temperature on its surface, and the temperature on the surface depends on the age and mass of the star. It can be from a thousand kelvins to hundreds of thousands of kelvins. According to the appearance of the color spectrum, we have different classes: O, B, A, F, G, K, M. We obtain these classes using a spectrograph. This device uses a prism to separate light into a spectrum. This gives us more precise data about the star we are analyzing. The stars of groups O, B, and A are mostly white or light blue, the stars of class F are yellowish, the stars of class G belong to the yellow stars, the stars to orange, and to the others the red stars.
