NASA DONKI Get High Speed Streams

Search NASA DONKI for High Speed Stream (HSS) events in the solar wind. HSSs originate from coronal holes on the Sun and can cause minor to moderate geomagnetic storming when they interact with Earth's magnetosphere. They produce recurrent geomagnetic activity patterns (27-day cycle) and are a major source of space weather disturbances during solar minimum. No API key required.
