The Sky Above the First Fleet

The Sky Above the First Fleet

On this Australia Day, think back to the night of Saturday, 26 January 1788. It is recorded that it was clear weather. The sky above the First Fleet at Sydney Cove would have included two bright planets – Jupiter in Taurus (the constellation in which it is currently located) and Mars in Gemini. The Moon, three days past full, would have risen just before 9pm. The constellation of Orion the Hunter and Sirius, the brightest star of the night sky, were also in the sky. The Southern Cross and the Pointer Stars would have been low in the SSE. And no light pollution – dark skies before moonrise. — Mark Rigby

Wambelong Fire (Coonabarabran)

Like me, I’m sure many of you have also been following the fire that went through Siding Spring Observatory and surrounds. It was particularly tough knowing it was almost 10 years ago to the day, that fires destroyed the Mt Stromlo Observatory in Canberra. If Mt Stromlo was the heart of Australian astronomy, surely Siding Spring is its soul.

Thankfully, lessons were learnt from that event and it appears that measures put into place may have saved the dozen or so telescopes on the mountain.

However, there has been major damage to the area, with the NSW Rural Fire Service reporting that some 40 properties and over 110 out-buildings have been confirmed lost as well as a large number of livestock and farm machinery. The local wildlife has also been hard hit.

Warrumbungle Shire Council has set up the Warrumbungle Shire Mayor’s Bushfire Appeal to assist residents who have been affected by the fire. As we’ve seen before, it’s such a dreadful thing to have happened. While much praise has been given to the Rural Fire Service for their tireless efforts.

As for the telescopes, here is the latest update from Kate Brooks, President of the Astronomical Society of Australia.

The square "dome" on the left houses the ANU's 2.3 metre telescope which stayed a comfortable 20 degrees throughout the fire. The dome to the top right is the new SkyMapper telescope, led by Nobel Laureate Brian Schmidt and built to continue the work of the Great Melbourne Telescope after it was destroyed in the Mt Stromlo fires. Temperatures there peaked at 65 °C. Source: Rural Fire Services

The ANU continue to post updates on the fire damage to Siding Spring Observatory.

A further visual assessment of the SSO site has confirmed:
– 3 buildings have been destroyed (The Lodge, a cottage and a storage building)
– 3 buildings have been badly damaged (The Visitors Centre and two sheds)
– 4 telescopes appear to have some smoke damage to their buildings

A new update on fire damage at the Mopra Telescope is available on the ATNF website.

Located down the mountain from SSO, the Mopra Telescope operates at millimetre wavelengths to investigate molecules within star forming regions.

Aerial footage of the Mopra Telescope and a brief first site visit from an SSO staff member on Monday indicated that there was significant fire damage to the onsite control building. This building contained an accommodation area, a control room and an equipment room. From the aerial photo it was clear that the accommodation area was burnt to the ground and yet the concrete roof above the control and equipment rooms appeared relatively intact.

Late yesterday afternoon two CASS staff with an RFS Inspector were able to visit the site and give a brief visual report on the inside of the equipment room. There is smoke damage but the equipment is currently intact with no obvious heat or fire damage. This is very good news. Before the equipment can be tested to see if it is still operational, the structural safety of the building must be assessed and the equipment must be made physically safe.

Amander Bauer, an astronomer at the AAO, continues to do a great job of posting the latest news on her blog.

And you can find some images of SSO during the fire at my post on the Museum Victoria blog.

State of the Dome

Dome15Jan2013a

Dome15Jan2013b
Here are a couple of images from yesterday afternoon showing the state of the Brisbane Planetarium’s Cosmic Skydome a week after closing for major upgrades. All of the seats and floor carpet have gone, along with the console, 12.5m diameter dome and supporting geodesic dome. The structure seen here around the inside is scaffolding installed in 1995 for better access behind the dome. New Layher beams were installed yesterday above the scaffolding and platforms will be installed on them today for future permanent access to the highest levels inside, e.g. access to insulation. Various speakers can be seen sealed in plastic. New concrete work is next on the agenda to bear the support ring for the new dome.

Cosmic Skydome Disassembly Underway

Skydome01

Two hectic days into the Brisbane Planetarium’s shutdown for upgrading the facility, the Cosmic Skydome has been stripped of projectors, LED lighting units, console, much of the cabling, seats and carpet. Displays in the foyer and gallery have been largely dismantled. The removal of the 12.5m projection dome and support structure is next – and involved!

Recent Brisbane Planetarium News

Coral01Apart from being busy preparing for the biggest upgrade since the opening of the Sir Thomas Brisbane Planetarium in 1978, Planetarium staff members were involved for the first time in the Brisbane International Film Festival during late November on a Friday night and a Saturday afternoon. Both sessions were sold out. Thanks are due to Warik Lawrance and Melbourne Planetarium for slicing the content for the Friday night.

Brisbane Planetarium Upgrade

STBP mega-pano 4 - screen

The Sir Thomas Brisbane Planetarium will be closing from Wednesday, 9 January 2013 and re-opening to the public on Easter Saturday, 30 March 2013. During this time, the Planetarium’s Cosmic Skydome projection dome will be replaced, a Megastar-IIB optical star projector and new console added, new projectors installed for the digital system, computers upgraded, seats refurbished and carpet replaced. The foyer, gallery and shop also will undergo major changes. APS members will receive a preview of all of this at APS 2013, which will be held on 23/24 March 2013.   N.B. APS 2013 has now been moved to 22/23 April.

Tycho is back

Tycho in the shop

It is with great delight that we can announce that Tycho has returned to the Scienceworks gift shop.   It has been quite a few years since a Tycho soft toy was available.  Many of the original soft toy Tychos were given away at the 2006 IPS in Melbourne and they have become quite rare since then. 

The new Tycho soft toy has poseable legs and ears, is fun to play with and cuddly to boot.  Welcome back Tycho!

Eclipse Megamovie Project

Hope everyone is gearing up for Australia’s solar eclipse. It’ll be my first chance of totality, so I’ve got fingers crossed that the clouds will stay away.

I wanted to let you know about the Eclipse Megamovie Project. It’s about using smartphones to upload images and videos of the Sun during totality and the Space Sciences Laboratory in California will combine the footage to create the first ultra-high time resolution movie of a solar eclipse. It’s sure to be spectacular, showing the evolution and dynamics of the corona and photospheric prominences, and we can help make it happen.

This project is supported by the US National Science Foundation and is a collaboration between the University of California and the High Altitude Observatory at the National Center for Atmospheric Research in Colorado. It’s the first time this has ever been attempted, and they’re got the technology side all sorted, now they just need to get the word out and encourage contributions!

Good luck everyone with your eclipse endeavours and please help spread the word.

Fisheye filming

Further to my earlier post on filming with the Red Scarlet and fisheye lens, we finally took it out on the road. The following with the gorilla mount is my favourite shot since it looks so parasitic on the front of the vehicle. In the end though it was to “wobbly” so the second option was used … rock solid.

ImageImage

Summary: 30fps, 2300 circle fisheyes, 20 minutes on a 64GB SSD.
