Aurora Australis at Perth Observatory

Aurora Australis at Perth Observatory on the 8th September 2017

There’s a big buzz around aurora activity at the moment, with the large solar flares erupting from the sun causing potentially good conditions for aurora to be visible. On the 8th September I and what seemed like half of Perth were out to photograph the Aurora. The hard decision is always where to go and in this case limiting factors were it being friday after a busy week of work, the almost full moon rising at 8pm, and large areas of cloud about the state. Given all that I decided to make the short trip to the Perth Observatory where I volunteer.

I took a couple of hours of time lapse from two cameras. This photograph is from my Canon 6D using the Samyang 24mm f/1.4. It is largely a single frame utilising some data from two other frames for masking out some bright lights in the foreground (it was a public viewing night).

Pink aurora is visible across an area of the southern horizon. It would have been extending only a few degrees above the horizon but is quite noticeable in the raw and processed frames. The aurora was not visible to the naked eye. Above the aurora australis you can see the Large Magellanic Cloud. The sky is lit by the moon which had risen a little at the time, but blocked by cloud enough to not illuminate the foreground. The foreground features the domes of the Perth Observatory lit by the red lights of tour guides hosting a group of public on one of the regular Night Sky Tours.

Now to work on the time lapse!

Aurora Australis

I managed to spare some time on the 2nd & 3rd November 2015 to do a spot of aurora chasing. Still only local, but an opportunity to get out and try or a few shots. The 2nd turned out to be not so good, a brief aurora show followed by heavy dew and then cloud. The 3rd on the other hand turned out quite pleasing with a nice in-camera show of aurora. Here are some photographs from Lake Leschenaultia in Chidlow, in the hills of Perth Western Australia. There is nothing special about this location for Aurora, it’s simply just around the corner from where I live so convenient with reasonably dark and low southern horizons which is what you need for aurora.

Trees frame the Large and Small Magellanic Clouds in the sky above the lake. Subtle green and blue tones in the night sky complement the dark silhouettes.

Subtle colours fill the sky where the Large Magellanic Cloud is also visible. Foreground reeds and trees provide nice framing for the water.

Beautiful silhouettes on the shores of Lake Leschenaultia. The Magellanic Clouds (Large and Small) overhead in the night sky filled with stars, and reflecting in the lake.
