There\u2019s enough trouble on this planet already that we don\u2019t need new problems coming here from the sun. Unfortunately, we can\u2019t yet destroy this pitiless star, so we are at its mercy. But NASA at least may soon be able to let us know<\/a> when one of its murderous flares is going to send our terrestrial systems into disarray.<\/p>\n

Understanding and predicting space weather is a big part of NASA\u2019s job. There\u2019s no air up there, so no one can hear you scream, \u201cWow, how about this radiation!\u201d Consequently, we rely on a set of satellites to detect and relay this important data to us.<\/p>\n

One such measurement is of solar wind, \u201can unrelenting stream of material from the sun.\u201d Even NASA can\u2019t find anything nice to say about it! Normally this stream is absorbed or dissipated by our magnetosphere, but if there\u2019s a solar storm, it may be intense enough that it overwhelms the local defenses.<\/p>\n

When this happens, it can set electronics on the fritz, since these charged particles can flip bits or disrupt volatile memory like RAM and solid state storage. NASA relates that even telegraph stations weren\u2019t safe, blowing up during the largest on-record solar storm, 1859\u2019s Carrington Event<\/a>.<\/p>\n

While we can\u2019t stop these stellar events from occurring, we might be able to better prepare for them if we knew they were coming. But usually by the time we know, they\u2019re basically already here. But how can we predict such infrequent and chaotic events?<\/p>\n

A joint project between NASA, the U.S. Geological Survey, and the Department of Energy at the Frontier Development Lab has been looking into this issue, and the answer is exactly what you\u2019d expect: machine learning.<\/p>\n

The team collected data on solar flares from multiple satellites monitoring the sun, as well as from ground stations watching for geomagnetic disruptions (called perturbations), like those that affect technology. The deep learning model they designed identified patterns in how the former leads to the latter, and they call the resulting system DAGGER: D<\/b>eep leA<\/b>rninG G<\/b>eomagnetic pE<\/b>rtuR<\/b>bation.<\/p>\n

Yes, it\u2019s a stretch. But it seems to work.<\/p>\n

Using geomagnetic storms that hit Earth in 2011 and 2015 as test data, the team found that DAGGER was able to quickly and accurately forecast their effects across the globe. This combines the strengths of previous approaches while avoiding their disadvantages. As NASA put it:<\/p>\n

\n

Previous prediction models have used AI to produce local geomagnetic forecasts for specific locations on Earth. Other models that didn\u2019t use AI have provided global predictions that weren\u2019t very timely. DAGGER is the first one to combine the swift analysis of AI with real measurements from space and across Earth to generate frequently updated predictions that are both prompt and precise for sites worldwide.<\/p>\n<\/blockquote>\n

It may be a bit before you get a solar alert on your phone telling you to pull over or your car might stop working (this won\u2019t actually happen\u2026probably), but it could make a big difference when we know there\u2019s vulnerable infrastructure that could suddenly shut down. A few minutes\u2019 warning is better than none!<\/p>\n

You can read the paper describing the DAGGER model, which, by the way, is open source, in this issue of the journal Space Weather<\/a>.<\/p>\n<\/p><\/div>\n
