NASA Trying To Develop Solar Storm Warning System

Written by ANDY TOMASWICK on . Posted in Current News

We’ve touched on the hazards of solar storms plenty of times in the past. We’ve also recently started reporting even more stories involving some sort of AI, especially in the last few months since it has come back to the forefront of many discussions around technologies

So it should come as no surprise that a team at NASA has been busily applying AI models to solar storm data to develop an early warning system that they think could give the planet about 30 minutes’ notice before a potentially devastating solar storm hits a particular area.

That lead time is thanks to the fact that light (i.e., what radio signals are made out of) can travel faster than the solar material ejected out of the Sun in the event of these solar storms. In some events, such as one that impacted Quebec around 35 years ago, they can shut off power for hours.

More extreme events, such as the Carrington Event that happened more than 150 years ago, can cause massive destruction of electrical and communication infrastructure if they were to happen today.

Scientists have long been aware of the problem and haven’t sat idly by. At this point in our species’ exploration of the Solar System, plenty of satellites are looking at the Sun that can be used to identify these solar outbursts.

Some of those satellites include ACE, Wind, IMP-8, and Geotail, which supplied data to the NASA team. But, as any AI researcher can tell you, in order to develop a predictive model, you have to tell it what it is meant to predict.

Knowing simply that a solar storm is on its way is only one part of the battle – you also have to know what kind of impact it will have on the Earth when it hits there. So the researchers also collected data from surface-based stations that were also affected by some storms that the satellites detected.

The scientists then set about training a deep learning model, which has recently become almost a household word. In this case, they named it DAGGER, and it has some pretty impressive specifications compared to existing predictive algorithms that have attempted to do the same thing.

Most notable is its increase in speed. The researchers, led by Vishal Upendran from the Inter-University Center for Astronomy and Astrophysics in India, claim that the algorithm can predict the severity and direction of a solar storm event in under a second and that it is capable of making a prediction every minute.

Previous attempts by earlier algorithms would take orders of magnitude longer – almost to the point where they would give hardly any warning time before a storm hit the Earth.

Part of that struggle with timeliness was because it was computationally challenging to calculate where a storm might hit anywhere on the globe. That is another step forward for DAGGER, which can perform its quick prediction logic for the entire Earth’s surface area.

Making such predictions locally is extremely important – at any point in time when a solar storm might hit the Earth, half of the globe will be protected by the planet’s entire bulk – in a state of what we commonly refer to as “night”.

This combined speed of prediction with the ability to apply those predictions to an entire globe makes DAGGER a considerable step forward in predicting and accurately responding to potential hazards from solar storms. And it is launching on an open source platform just in time to collect plenty of data as the Sun ramps up to the peak of its 11-year solar cycle in 2025.

That gives utility and communication companies a few years to integrate DAGGER into their threat assessment systems before the most severe weather comes.

While there might not be any wailing sirens similar to the tornado warning sirens, that we have here in the Midwest of the US, at least the right people will be made aware of the danger faster than they would have been before.
