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!
