Geek out with these space and science events in Canberra



There are plenty of events coming up for Canberra space and science fans, with an inevitable clash unfortunately:

  • European Space Agency mission experts on the Rosetta Mission
  • Nobel Laureate Professor Brian Schmidt on the future of science
  • Peter Garrett on ecology and climate science
  • Anna Frebel (MIT) on the search for our galaxy's oldest stars
  • Badri Younes (NASA) on the interplanetary communications and navigation network.

All of these events are free. Descriptions and details below are as published by the various event organisers.

Public stargazing on Mount Stromlo this Friday night



There are only three more public viewing nights scheduled for this year on Mount Stromlo. Daylight savings makes dates over summer too late for the kids.

So far the weather forecast is looking good, which will make a nice change. But it always pays to check the all-sky camera on the MSO website to make sure before you rug up and set off.

And please do remember to rug up, same for your kids. It's a mountain top, and often a lot breezier and colder than down at your home. Your kids may be climbing a cold metal step ladder to a big scope, so make sure they have gloves. A snow jacket is my standard kit for a night on Mt Stromlo...

Despite a half moon that will be fairly bright, viewing of Saturn should be good, and there'll be a lot of other cool sights for first timers like binary stars, globular clusters, and perhaps a look at the brand new nova that was just discovered today.

The event starts at 7pm, until about 9. See you there!

Gorgeous wing-tip vortices from an airliner landing in fog

This short video is a sleeper...

It's only 50 seconds long and you start wondering whether it was worth the click through.

Then...wow.


I am so going to have to take the camera out to the Canberra Airport next foggy morning...

It's a Swiss Air A340 landing in Zurich, and was published in January this year by Andy Ruesch. And it's a pretty good example why formation flying is kind of dangerous.

Public stargazing this Friday night—Mount Stromlo. I'll be there. Will you?

The members of the Canberra Astronomical Society will be back up on Mount Stromlo this Friday night for the second of this year's joint ANU/CAS public stargazing nights.

After the full-cloud washout from last month, if the skies are clear this week, we expect a huge turnout. 500 people is normal, and on one pretty busy night last year, I was sure every one of 500 people checked out Saturn through our telescope...

It will be the first public outing for my new telescope and the big wide-field eyepieces I bought especially for these public viewings. I've been setting it up to control the new equatorial mount via bluetooth straight from Stellarium on a notebook PC, and using a wireless gamepad for steering. This process uses programs called ASCOM EQMOD and Stellarium Scope.

It would be nice if I could get some clear sky to actually test it first…There's one crucial component that I haven't tested yet—the sky alignment program Alignmaster. :-/

Please make sure you check the Mt Stromlo All-sky Camera before you set off, to see whether anything is visible:

Here are the details posted by ANU. Note the 'warm clothes' advice—it does get cool and windy up there! Ski jacket is my standard gear…
The Mt Stromlo Observatory in conjunction with the Canberra Astronomical Society invite the Canberra community to attend our public observing night.
Come and see the rings of Saturn, the craters of the moon as well as beautiful star clusters and nebulae. On the night attendees will be taken on a ‘tour of the universe’ with talks by astronomy experts and observations on several telescopes.
This event is free and open to the public. No bookings are required.
Warm clothing is recommended. In the event of cloudy weather, star gazing will be cancelled. You can check out the weather at Mt Stromlo using our all sky camera.

We are now connected to the NBN. Here's a run-down on the install. And the speed!

Today was the long-awaited connect to the National Broadband Network day. Yay!

After being involved for years in the community campaign to get Gungahlin's parlous internet access upgraded, it was lovely to be able to see the end result.

We've been paying Telstra the same price as someone in Sydney pays for an ADSL2+ service running at 20Mbps, but getting only an 8Mbps service. Except what it really ran like was this (speedtest.net):


And that was at a good time, with low congestion.

We went looking a while back for the NBN package that seemed the best-rounded solution of the well-respected major providers, so we'd already changed our internet and phone service to iiNet in preparation.

So as soon as we knew the NBN was ready in our area we got the install booked through iiNet, for "between 8 and 10am" today. The process of the install kicked off well, with a reminder call the day before from the contractor, who I found out later has been brought in from Melbourne because NBN Co has been having troubles with their prime contractor. I'll explain the whole process here so you know what is involved and can plan your conversion without surprises.

Sunrise from the roof this morning

What's not to like about climbing up on your roof first up in the morning to catch a gorgeous sunrise?

Just a quick post with three nice pictures from this morning. Loved the reflection off the solar panels.

Wide shot, looking over Goorooyaroo Nature Reserve and Burnt Stump Hill:

What I've been reading lately

Just an archival catch-up of recent The Beach House Weekly—my Paper.li auto summaries—of an interesting few weeks in science, space and Australian politics.

From rockets to meteorites, Roxon to Rudd, novas to Nobels, planet hunters to metric hunters.

Canberra bashing. We are over it. My response to Fairfax and @feed_the_chooks

The Melbourne Age has run a piece by Martin McKenzie-Murray (@feed_the_chooks) that has raised a lot of ire among Canberrans. It's insidiously more than the usual Canberra bashing we expect from Sydney and Melbourne journalists in the way it tries to portray it is somehow different and more rational than the usual dumpings.

To compound the offence, the Age's stablemate The Canberra Times has followed up with a defence—not of Canberra, but of its journalist...

I want to write a piece deconstructing the original article line by line. But in the meantime, here is my response to the Canberra Times defence, as lodged via their Comments function:
We know out city is not perfect. Politicians make mistakes. Transport and land use planners make mistakes (boy do they make mistakes). But the strength of WBG's vision is that the city has largely withstood the worst efforts to derail (light rail pun intended) its innovative alternative to squishing everything into one choked CBD.

But what we are utterly sick of is Melbourne and Sydney journalists scoring cheap points by indulging in the usual Canberra-bashing "stacks on" that repeatedly gets churned out of tabloid and tabloid-esque media.
It's not an over-reaction. It's a reaction to the entire piece. Cherry-picking a few of the more measured phrases Megan, and a few of the more OTT reactions, does not negate the negativity being promoted by the piece as a whole. Not that it is just plain wrong.
Newspapers once controlled the feedback via their iron grip on the Letters pages. But no longer. We now have social media and we have blogs with surprisingly large readerships. We can now fire back when we've had enough of being dumped on by some fly-by-night visitor who didn't venture outside the Inner South. We have had enough. And we expect a better defence from our own newspaper.
Update: Decided not to bother with the critique of the original article. The author was obviously milking the backlash for all the exposure he could by teasing it along on Twitter (blatant click-baiting), so easier to let it die...

As a very long façade, it must have been a massive undertaking to light up this building, so there aren't many individual changes. It does look lovely with the reflections across the pond.

Can a solution for Canberra's Bunda Street Shared Zone be salvaged from these proposals? My submission.


The ACT Government is planning to redevelop a key roadway in the Canberra CBD called Bunda Street. At present this corridor is heavily choked during weekdays, with numerous pedestrian crossing points, almost continuous streams of pedestrians moving between major destinations, and car drivers who simply can't get it into their skulls that this is a really dumb place to try to drive through at lunch time...

It's not clear from the documentation on the Community Consultation website, and the terms of reference for the design competition are not given, but the public announcements made by the Government at the launch time indicated that a Shared Zone solution was desired.

Following is my submission. I've also taken the opportunity to pass on my thoughts about the design of the rest of the Civic Cycle Loop that is currently under construction (has been for many months, dragging on endlessly...).

You can also comment on the proposals—by 5pm Monday 4 March 2013.


GTA consultants: The Bunda Street shareway.

The GTA concept is the most faithful implementation of the Shared Zone concept. However, it fails to incorporate footpath and roadway blended seamlessly, with traditional kerbing removed. Only through such treatment will car drivers realise they do not have right of way and treat it as a traditional roadway. The proposal to raise the "roadway" to the footpath height will present flooding risks. The solution is to instead remove the kerbs and blend the entire corridor from facade to facade into one unbroken line, with central drainage.

This new paving treatment should go from building to building and not stop at the lot line as is happening around Moore Street, leaving jumbled paving treatments. Implement a benefited area levy to cover additional costs if necessary, with agreement of building owners.

The idea of actually placing tables and chairs in the choke points is silly and dangerous and fails to recognise that there will still be cars and cyclists on this corridor.

The stick-on stencilling could be subject to early failure and expensive maintenance.

The concrete embossing is interesting but it is likely the indents will hold dirt etc as well as presenting a significant trip hazard for people in heels. Overall, this treatment may be overpowering over such a large area.

There remains a risk that cyclists and pedestrians will not respect or notice each other enough, with incidents highly likely. A segregated bikeway would resolve this.

Asteroid 2012 DA14 caught on camera by Canberra astronomer Dave Herald

Amateur astronomer at Murrumbateman, near Canberra in Australia, Dave Herald has captured a number of photos of near-Earth object (NEO) asteroid 2012 DA14 as it closed in on Earth prior to its incredibly close pass this morning. This photo was four hours before closest point:





His description:
Image is a 4-min exposure from 15H 01m UT to 15H 05m. This bracketed the time when the asteroid was furthest south from the observing site (E07). The image indicates the path was about 7" south of predicted.
This is at five hours:





Increased speed, and change in direction as the asteroid gets close to the south pole, are readily apparent. Image is a 3-min exposure. Asteroid is at -85.4 deg.
This is at six hours:

Before the Canberra storm was the build-up... My 1:20 timelapse

iPhone shot out the other side of the house while the timelapse was shooting
No fireworks for this Australia Day - not the artificial kind anyway. But plenty of the natural white kind!

And before the big storm hit Canberra, there were some dramatic clouds during the build-up.

It was all very reminiscent of South-East Queensland actually...

Enjoy my first YouTube upload—1849 frames, four seconds apart, covering from 3:56pm to 6:20pm in one minute 19 seconds:



Pity Picasa doesn't fade out the sound at the end...

Siding Springs Observatory damaged by bushfire (FINAL UPDATE)

Anglo-Australian Observatory, Siding Springs, in the firing line


Australia's premier astronomy site, the Sidings Spring Observatory in the Warrumbungle Mountains near Coonabarabran, has been damaged by an out of control bushfire this afternoon.

All staff were evacuated from the observatory in time. Temperature sensors shot to 120 degrees Celsius as the fire-front passed over the site. Flames have been caught on webcams.

Weather readings from the site, posted by English astronomer James Allen, currently working at SSO.
Note the peak temperature!


The Rural Fire Service has reported two nearby properties as destroyed and the observatory as "damaged". A journalist has cited a good RFS source as saying the damage "is significant".

Canberra's bushfire sunset last night made for tricky photography

Bushfire mountains

A smoky sunset after yesterday's bushfires scattered all around the Canberra region made for very challenging photography. For this beginner anyway. There was so much smoke, the sun was blowing out very badly. There are probably some Photoshop tricks to get around this, but I don't know them. I think the best photo is this one of Black Mountain - without the sun in it.

Sunset over the Brindabellas

I liked the way the sun was reflecting golden off the grass seedheads in this next one, looking towards the mountains from Horse Park Drive. But the sun was blown way out... A little bit of post needed: I backed off the exposure a little and lifted the shadows to try compensate for the sun:

After a 38 degree day comes a cracker storm! Check these lightning photos.

20130105 Lightning IMG_3920

It was hot outside today, and it will be hot again tomorrow. But in between we've had a great series of storm cells passing over, with some excellent lightning.

I pointed the camera out the upstairs window, and set it on automatic shooting with a programmable remote control. Unfortunately there's nothing automatic about the processing stage...

But after sorting through some 600 frames of 30MB RAW files, it came down to 13 keepers.

Eyes up! Some bright ISS passes for Canberra this week. Iridium flares too!

Photo by Ashley Kerlin 
It's that time again when we get to look up and see the only place where humans live other than on Earth zipping across our skies. The International Space Station has a number of very bright passes coming up over the next few days—some at fairly family-friendly times (given it's school holidays anyway).

For Canberra people there is a very bright, high and long pass each of the next five nights, including tonight. Anything from this table above -1.5 is quite bright (above being a larger negative number).

It's great fun to try to catch the ISS in a photograph. Set your photo quality to the highest possible (RAW if you have it), your lens to a wide zoom, your aperture small, shutter to 30 seconds or more, prefocus on something as far away as possible and then turn autofocus off. Set your camera on a tripod pointing towards where the ISS pass will appear. Use a wired or wireless remote if you have it, otherwise set the self-timer to two seconds to give any button-pressing vibration time to settle before the shutter opens.





I also like to frame up a foreground object as long as it isn't lit too much. Conversely, if the foreground is very dark, you can 'paint' it during your exposure with a second of light from a torch. Photoshop will also allow you to brighten 'shadows' afterwards to highlight your foreground.
