There is plenty more colour in the night sky at this time of year. The variety of colours and the spectacular shapes of an aurora create a visual spectacle that captivates and inspires.
Shetland Aurora Hunter on Facebook provides all the updates and information you need to be able to tick off your bucket list. Although most auroras we see are a green colour, often low on the horizon, we are currently in a period where we can see lots more colourful auroras. This is called Solar Maximum, and although we are just after the peak, there is plenty to look forward to.
February and March are good months to see and photograph the aurora due to the spring equinox, which is where Earth’s pole aligns with the Sun, providing the ideal conditions to receive more solar particles, which create the aurora.
There is still plenty of activity, and with every aurora being different, you just never know what you are going to see. When you know that the aurora is due and with clear or partly clear skies head out to a dark site away from light pollution, we have plenty in Shetland.
Your eyes need to adjust to the darkness; this takes about 10 minutes. Don’t destroy your night vision by putting on a torch. Look north and hopefully with an active aurora you will start to see rays reaching high into the sky or a colourful curtain ripple across the sky.
These are the times when the sky is full of colour, the greens meet purple or even red when very active. If we get a major alert, you may see the aurora reach so high in the sky that it is directly above you. This is called a corona, and it can move very fast, with shapes and colours changing rapidly.
Most people may be disappointed at observing an aurora because they cannot see all the colours that a camera can. Using a camera can be good at detecting where the aurora is showing. Make sure you use a tripod, as you will be taking photos at a very slow speed. Ramp up your ISO to 6400 on a dark night, open the lens as wide as possible, F2.8 or lower and a speed of 15 seconds. This will start to reveal the true colours of the aurora.
