2013 Astronomy Open Night at Macquarie University

16 04 2013

The Northern Sydney Astronomical Society, along with Macquarie University Association for Astronomy and the Department of Physics and Astronomy, wants to invite  the Community to join us in the celebration of the 25th Anniversary of Macquarie University Astronomy Open Night. A few months earlier this year, on Saturday 18th of May from 5:30 to 9:00 pm, the plan for the night covers a broad range of activities, including stargazing through telescopes, a fantastic Planetarium show and display (very popular!), a lot of activities for the little ones (and no so little too!), exciting Science displays and a very interesting talk about Extremely Large Telescopes, given by Professor Warrick Couch. There’s also BBQ and refreshments around, to keep the energy up!.

NSAS members, along with other Astronomy Societies of Sydney, volunteer with Telescopes and information stands to show the people the wonders of the sky. Discussions are held with the public about telescopes and other equipments, sky objects, weather and light pollution, among other spontaneous subjects. It is a night for learning and enjoyment for the families.

I hope you come along. See you there!

As the Theory Group is in recess for 3 months, the first activity this month is next Tuesday the 16th, which is the General Meeting at 7:30 PM. Our speaker this month is Dr Mark Phillips from Las Campanas Observatory, who will speak on “Exploding Stars and Our Place in the Universe”. Tuesday the 23rd will be session 2 of the New Astronomers Group, also at Regis Hall at 7:30.





NAG Commences Tonight Tuesday 26 Apr

26 03 2013

In case anyone has missed it, the NAG for 2013 commences tonight at 7:30 PM at Regis Hall, St Ignatius.





What’s on in March

6 03 2013

I would like to update you with the coming March events. Let me know via NSAS Gmail if I have missed anything.

• Committee Meeting – being 7.00pm Tuesday 12 March at the classrooms below Regis Hall, which will be followed by -
• Theory Group at 7.45pm on the same night
• General Meeting 7.30pm Tuesday 19 March at the classrooms below Regis Hall
o Guest Speaker Dr Joao Bento, a post doctorate student at Macquarie Uni, who will be speaking on “Transiting Exoplanet Search With Small Telescopes” – should be an excellent talk so come along and take part
• Observation Nights – the Observation Night for March is Friday 8th, with the backup being Friday 15th. Keep an eye out on the site for Tim’s advice as to whether the night is on or off. Visitors and interested community members are especially encouraged to simply turn up – no telescope required. Vast or nil experience in observing is equally appropriate.
For your information, Irene Justiniano has volunteered to act as co-ordinator for all Outreach activities. Her role will be simply to monitor outreach, by way of ensuring each activity has a Project Manager in place. It will be the role of the Project Manager to undertake the various requirements of the night, including liaison with the organisation (eg a school, or council), checking out the site, arranging volunteers with telescopes, and ensuring any support or promotional material is on hand. It will be the role of the committee to ensure that appropriate guidelines are in place to assist the Project Manager.

Outreach activities coming up in April / May are:
- Parramatta Star Party (13 April – Project Manager to be appointed – volunteers?)
- West Ryde Primary School (9 May – Project Manager Peter Korber)
- Ryde Secondary College (date and Project Manager to be confirmed – volunteers?)
- Macquarie Open Night (Project Manager Bob Fuller – 18 May)

Of special note is that the New Astronomers’ Group has been confirmed as starting up in March – being the 4th Tuesday (26 March). Bob Fuller and Geoff Unsworth have put together a full syllabus of material over a seven month period, and covering a large selection of introductory topics including everything about telescopes and how to use them, what to look at (solar system and deep space), how to look at them, and astrophotography. Practical demonstrations are also part of the course.

We believe the new NAG course will be of immense benefit to a significant number of our new (and maybe not so new) members, and to the family and friends of our members. The course is available to students and the wider community and we are also looking at ways to promote the course to the community, including using our website to assist with promotion. I ask all members to think of ways in which they may be able to get the message out there, so that this course enjoys maximum exposure, and consequent flow-on benefits for NSAS. A once only fee of $5 will be charged to non members to attend, and which will be allocated to the membership fee if that option is taken up.

Please note that all NSAS activities at the College will from March onwards, be conducted in the classrooms below Regis Hall. The classrooms should suit our needs much better than the Hall itself.

Regards to all

Bruce Retallick





Observing Report – 15 February

16 02 2013

Observing was at NTGC last night with a very unclear forecast on clouds, but even with some heavy cloud to the South in the evening, observing was able to go ahead. There were six members present with three scopes, and eight visitors, many of whom had come as visitors before. The big draw was Comet C/2012 F6 Lemmon, which was almost directly under 47 Tuc. The sky to the South was variable in seeing all night, but 47 Tuc looked impressive, and the comet, being just a fuzzy ball, was probably a bit disappointing to visitors. We also had a big search all night for the asteroid 2012DA14, which should have been in the vicinity of the comet, but all of us with Sky Safari on our IPads couldn’t find it in the list, and the HeavensAbove details for RA and DEC were suspect. After the clouds rolled in, we found we had been searching too high in DEC, but too late. The sky overhead and to the North was much better, so M42, Ghost of Jupiter, Eta Carinae, and several other favourites were enjoyed.





Message from our new President

10 11 2012

Hello all NSAS members

As newly elected President of NSAS I would like to bring you up to date following the recent monthly meeting and AGM. Bob Fuller was away in the US and so as Vice President I took the chair for the monthly meeting. I noticed the attendance at the Monthly / AGM was fairly low, which was hard to understand. Perhaps we should put on a full buffet next year, but otherwise I can’t understand why attendance at an AGM would not be stronger!

At the Monthly meeting, quite a few points came up, many of which had been raised at the Committee Meeting. In point form:
- Astronomy 2013 is now available (being ordered)
- expenses for the year exceeded income, and which point led to later discussion on whether the annual fee should be considered (it has been unchanged for decades)
- Macquarie Open Night was discussed (the event was held the next weekend and was very successful, though observing was restricted)
- the meeting discussed the prospect of sending out Reflections by email only, and whether that would affect many of our members – the Committee will consider further, but any member having a view on this should let the Committee know by email
- the Christmas Party is coming up – 18 Dec – a big attendance is hoped for, and members are asked to please bring a plate of their favourite goodies. Drinks are supplied.
- the Committee will work through a more formal procedure for assisting our visitors and new members
- Lawrie Webb will be setting up at Tantallon Oval to observe the partial eclipse of the sun, and he would be delighted to have as many join him as possible approx 7am Wed 14 November ie next week
- Bob Roeth was to hold (and did hold) the 5th Tuesday Mathematics in Astronomy later in October
- Publications available: Astrovisuals Calendar $9 (contact Bob Roeth); Paul Shallow has the 2 CD Ceduna Eclipse for sale at $5
- Geoff Welch Prize: the three winners of the $50 (each) and a copy of Geoff’s book and a Presentation Certificate were Arthur Boyd for “La Perouse’s Incomplete Voyage”, Irene Justiniano for “Clear with a Chance of Meteor Shower”, and Bob Roeth for “Magnitudes, Wikipedia and Errors”

After the Monthly Meeting the AGM was held and again I acted as Chairman in Bob’s absence (Bob was acting as NSAS operative covering the US election and its impact on NSAS, and world, amateur astronomy) . In summary:
- all went well
- a discussion on annual fees occurred, and the Committee will consider further and come back to the members
- the Committee will discuss reinstating the Gordon Stott Imaging Prize
- I provided some comment on the last 12 month’s activities for the club, including observations, the sub groups and field trips (to Canberra / Tidbinbilla and Coonabarrabran)

Prior to the elections for the next twelve months, appreciation was expressed to the outgoing Committee, in particular to Bob Fuller who as President and Vice President before that, has carried far too heavy a burden for NSAS for several years – it was agreed a small gift of appreciation should be purchased for Bob.
The Committee then stood down and elections for the next twelve months were held, with the following results:
President – Bruce Retallick
Vice President – Gordon Ogborne
Treasurer – Ken Schofield
Secretary – Irene Justiniano
Committee Without Portfolio – Peter Korda, Anna Koeneman and Chris Anderson
As President I thank those who have volunteered their services. There has been quite a turnover in Committee membership and over the next few months we will work on getting a handle across all those tasks that need to be undertaken. We have the benefit of the previous members having all offered their assistance – and this will undoubtedly be called upon!
I offered a few comments as President:
- my interests are fairly broad but unlike previous Presidents, I am not a technically oriented person, and will need support in those areas – I will not be able to take on any technical roles or lead in discussions
- I will be working on assessing our collective knowledge and expertise to ensure that we fully understand our capacities and commitments – and including that of our new members
- we must look after our visitors and new members better – we all have a responsibility to make them feel welcome
- we must all wear our name tags at meetings – such a small point, but so important
- we should pay some attention to formalising our aims and objectives, including the Outreach program, and in accordance with our capacity and our desires
Since becoming President I have noted many possible actions and points of interest. I look forward to bringing at least some of them forward for consideration, and to a successful twelve months.
Regards to all
Bruce Retallick





NSAS GM Next Tuesday the 18th

14 09 2012

The NSAS Sept GM will be at 7:30 PM next Tuesday the 18th at Regis Hall, St Ignatius. Our speaker is Dr Charlie Lineweaver from ANU, who will speak on “The Habitability of Our Earth and Other Earths”. His abstract follow:

For life-forms like us, the most important feature of Earth is its habitability.
Understanding habitability and using that knowledge to locate the nearest
habitable planet may be crucial for our survival as a species. During the past
decade, expectations that the universe could be filled with habitable planets
have been bolstered by the increasingly large overlap between terrestrial
environments known to harbor life and the variety of environments on newly
detected rocky exoplanets. The inhabited and uninhabited regions on Earth
tell us that temperature and the presence of water are the main constraints
that can be used in a habitability classification scheme for rocky planets.
Our compilation and review of recent exoplanet detections suggests that the
fraction of stars with planets is ∼100%, and that the fraction with rocky
planets may be comparably large. We review extensions to the circumstellar
habitable zone (HZ), including an abiogenesis habitable zone and the galactic
habitable zone.

Don’t miss this one!





Observing Report 25 May

26 05 2012

We tried out Howson Oval for the first time on a cold and windy night, so it was probably the worst weather we would experience there, as it is exposed. Unfortunately, it was only me and Jenny, a visitor joining NSAS, so we persevered for several hours and gave up at 8 PM, when it was clear everyone else stuck their heads out their doors and decided to stay in front of the fire.

Howson Oval is a great observing site, far superior to NTGC, once we do a deal with the Council about access to the security lights on the dressing shed. There are no streetlights visible, and the only lights on the horizon are The San to the north, but even that is hidden. We could see near the horizon for 360 degrees from the middle of the oval, and while not as good to the north as Golden Julilee, it’s not bad. Even better, the toilets were unlocked! (probably Council security forgot them). We’ll give Howson a go again on a better night.





NSAS GM Tuesday the 17th April

16 04 2012

Although our speaker has had to cancel due to family reasons, and we have not yet found a replacement, we have a plan……After the GM, we will run an interactive forum on subjects of interest to the membership, and if we have time, there will be a Powerpoint presentation on Indigenous Astronomy. Come along and join in. Visitors welcome, of course, and the meeting will be, as usual, at Regis Hall, St. Ignatius, at 7:30 PM.





Observing is ON tonight 13 Apr

13 04 2012

Observing is ON tonight at North Turramurra GC. Someone from NSAS will be there from 6:30 PM. Visitors welcome, as usual.
