Night Sky News: Possible Auroras from Massive Solar Storm?

This week’s titantic eruption seen on the surface of the Sun may have an extra surprise in store for skywatchers in the form of aurora borealis.  While the video taken by NASA’s Solar Dynamics observatory clearly shows that most of the superheated plasma in that giant flare blasted off the sun rained back down, a significant amount of  super charged particles managed to escape the gravity well of our star and headed out into space.  Known as a Coronal Mass Ejection (CME), this monster sized cloud many times the size of the Earth is travelling at about 3 million km per hour through interplanetary space and is predicted to give a glancing blow to Earth on Thursday, June 9th. 

 

Depending on how our planet’s magnetic field is oriented at the time of impact we may get a better than average chance of seeing a light show in the skies above.  According to reports on Spaceweather.com, scientists are forecasting at least a 30% chance of auroras occuring in higher latitude skies and around a 20% chance for mid-latitudes.  That means folks around the Arctic Circle will have the best hope of seeing something but if you live in darker areas outside of more southern cities you may have a chance .Our ability to predict these displays is still in its infancy and we just are not sure how intense the CME will be when it gets here – so it may very well be worth taking a peek outside.

When to look up?  Best time to see auroras is usually around local midnight when the sky gets its darkest. Face the northern sky and look low towards the horizon – that’s where you might see the first hints of a ghostly glow. If it ends up being an intense display then a larger portion of the sky may get enveloped with colours of orange, pink and purple curtains waving in the overhead sky. 

Also you might want to try and take a  photo of the auroras. All you need is a standard DSLR digital camera that allows you to adjust your exposure rate manually anywhere from 5 to 20 seconds. Set the camera up on a tripod with an ASA around 400 and timer for 2 to 10 seconds between shots so that you have a steady photo without any shaking.

While there are no guarantees we will see somthing – the only way to know for sure is to go outside and look for yourself.  Clear Skies!

    I saw the lights this morning, it stayed in the sky for about 2 hours until thick clouds covered it. Beautiful but a bit scary as this is the first time I saw something like that…

      There is a small chance as long as you have a clear night away from bright city lights.

    does this Aurora Borealis can be seen in our country tonight..?? (June 9,2011)..it seems it’s very interesting to witness these flares..^_^

  8. […] What’s the fallout for us here from this titanic fireworks show? THe solar eruption was considered a medium one by scientists and was away from the central region of the Sun.  Luckily the resulting giant particle cloud coming off of this event is not heading directly towards Earth – but we may still see some Northern Lights.  Check out my National Geographic column on what we might expect to see.  […]

    Thanks Andrew for that brief description. Currently it’s rainy and overcast here in the Austrian Alps but maybe clouds will open up a little bit. Hopefully. Cheers
