NASA, along with IBM, has released an AI model called Surya, which aims at enhancing space weather forecasting. Trained on about a decade of data from the Solar Dynamics Observatory, it is able to anticipate solar flares and eruptions as far as two hours in advance. Surya introduces the spectral block layers and transformer architecture to find faint patterns of solar activities with 16 percent more accuracy than the models used before. It has been tested on 2015 St. Patrick Day geomagnetic storm, in which it accurately simulated the event. It has been published as open-source so that worldwide cooperation is possible in order to enhance prevention of solar threats.
Context
-
Solar flares and CMEs pose a danger to satellites, power grids, aviation and the safety of astronauts.
-
Established forecasting techniques are sometimes not capable of early and accurate prediction of such events.
-
NASA wants to use AI-enabled heliophysics to prepare and resilience globally.
Key Points
Why It Matters
-
Solar activity may be involved.
-
Damage satellites
-
That is the reason why power outages on a large scale happen.
