NASA has released more information about the aurora posted above.

• What caused this display? On March 28th, the interplanetary magnetic field (IMF) near Earth tipped south, opening a 'crack' in our planet's magnetosphere. The fast solar wind had not yet arrived. Even so, there was plenty of slow solar wind in the area to flow through the crack and fuel the outburst.
