Interesting! Which direction does the Earth's spin point in this one? Also could you link a source for the data please?

This gif is actually pretty old and the exact source for the data not easily traceable.

Here's some real-time data from that satellite: https://www.swpc.noaa.gov/products/ace-real-time-solar-wind

@Magic Octopus Urn Thanks, that is pretty awesome. I will add that to the answer, if thats ok.

@SpaceBread https://space.stackexchange.com/questions/38428/what-is-being-shown-on-august-27th-from-the-noaa-ace-satellite I asked a follow-up about that data too.

# Does the magnetic field of earth restore?

(Asked by: username_0 on 2019-08-28)

The magnetic field of earth protects us from solar wind as we know it, but after the solar wind interacts our magnetic field.

Does the magnetic field of earth restore after it deflects the solar wind from the sun?

Remember that a magnetic field is just that: a **field** . There's no mass there. Its shape depends on the electromagnetic properties of Earth -- primarily the behavior of the outer core.  
When there's a significant Solar ejection, the electrically active particles in that mass cause local changes in the magnetic field pattern (equivalent to isobars , or lines of constant field strength, etc.) So long as the solar ejecta do not damage the Earth in any significant way, once the particles are gone, the field lines will revert to their default layout.
