NSAS February General Meeting

16 02 2012

The NSAS February General Meeting will be next Tuesday, location for this meeting only to be the Fr. Mac Pavillion (old sports pavillion we previously used). The time is 7:30PM, as usual. Our speaker this month is Franceso di Mille from the AAO and Las Campanas Observatory. His abstract follows:

Highly collimated gas ejections are among the most dramatic structures in the universe, observed to emerge from very different astrophysical systems—from active galactic nuclei down to young brown dwarf stars. I will present the discovery of a giant, highly collimated jet from Sanduleak’s star in the Large Magellanic Cloud (LMC). With a physical extent of 14 parsec at the distance of the LMC, it represents the largest stellar jet ever discovered, and the first resolved stellar jet beyond the Milky Way.
I will also talk about the Las Campanas Observatory and the Magellan telescopes.

Theory Group on the 14th, and change of venue for GM on the 21st

13 02 2012

Just a reminder that NSAS activities restart tomorrow night with the Theory Group at 7:45 at Regis Hall, and that the venue for the GM for next Tuesday the 21st is changed back to the Fr. Mac (sports) Pavillion due to a scheduling conflict. Hope to see you at either/both. If you haven’t paid your membership renewal, I’d suggest doing it tomorrow, as otherwise the Committee will generate a letter asking whether you wish to remain a member.

December Events and Saturday’s Lunar Eclipse

7 12 2011

Just to remind those of you who might have forgot, this coming Saturday night the 10th there is a total lunar eclipse visible from Eastern Australia. It starts at 10:45 PM and is at totallity about midnight. Hopefully the weather will be better on the night. The Society will not run any program for this, as it is so late at night.

I’ll take this opportunity to remind you of the events for December. Next Tuesday the 13th will be the Theory Group at 7:45, and on Tuesday the 20th we will have the Society Christmas Party, which will revert back to the old format of “bring a dish”. I’ll get back to you with more details later. All meetings are at Regis Hall, as usual.

Tuesday Astronomy and Mathematics Lecture

25 11 2011

Bob Roeth will continue his series of lectures on astronomy and mathematics next Tuesday the 29th at Regis Hall, 7:30 PM. Subjects include:

Co-orbital moons of Saturn and their swapping inside running to outside running – a case of the process predicted by Charles Darwin’s son , George
Apparent horse-shoe orbits
The inter-planetary highway involving Lagrangian points L1 and L2
A simplified look at the Roche Limit – a limit to close approach without fracture – a tidal effect.
Isaac Newton’s simple geometric derivation of a somewhat generalised form of Kepler’s Area Law – generalised to shapes other than ellipses – all being examples of ‘central force’.

David Malin is our speaker for the Nov General Meeting next Tuesday the 15th

11 11 2011

Next Tuesday the 15th is the NSAS November GM. If you haven’t been making it to the GMs, maybe you want to make an exception for this one, as David Malin, the man who invented modern three-colour astrophotography while a scientist-photographer at the AAO, is our guest speaker. Those of you who have heard him speak before know that he is a very entertaining and knowledgeable speaker, and will have points of interest for anyone who is an amateur astronomer. David will be speaking to NSAS on the history of astrophotography, and I recommend everyone in the Society who can get to Regis Hall next Tuesday to make it for this exceptional event. As usual, visitors are welcome, and the GM starts at 7:30 PM. See the home page of our website for directions if you haven’t been before.

NSAS Events for November

1 11 2011

NSAS this November will have the Theory Group on Tuesday the 8th at the new time of 7:45. The Nov General Meeting will be Tuesday the 15th at 7:30, and the speaker is David Malin, the famour AAO astrophotographer. If you ever make it a GM, you should make it to this, as David is a fascinating speaker who will talk on the history of astrophotography. All meetings are at Regis Hall, St. Ignatius. Observing this month is Friday the 18th, and would have been on the 25th, however the Field Trip to Coonabarabran will likely take our Observing Officers away, but there could be Observing if someone is available. Finally, the second Field Trip of the year will take a group to Coonabarbran for a tour of the AAO, followed by dark-sky observing with either own scopes or at a commercial observatory. It’s not too late to join up, so just let me know.

NSAS Activities for September

3 09 2011

We start off September tonight with the NSAS Public Star Party for the Lane Cove Cameraygal Festival. If you’re not involved, and want to come along, the details are on the NSAS website. Tuesday the 13th the Theory Group will meet at the new time of 7:45. Tuesday the 20th is the General Meeting, where we will vote for the Geoff Welch Prize winner(s), and our speaker is Dr David Frew from Macquarie University. The topic is something related to planetary nebulae, his specialty (details later). The NAG finished up last month for this time around, so we will have to wait for a new group of budding observers next year to start up again. Observing at N. Turramurra this month is the 23rd and 30th.
