It missed us by 9 days

okay, so I understand that solar flares and geomagnetic storms disrupt technology and can start fires, etc. Has anyone done any investigation on the possibility that larger solar flares might interact with asteroids or meteors due to the magnetic activity? I know we had that 1989 event with the huge geomagnetic storm, and then coincidentally 10 days later an asteroid nearly the size of a mountain almost struck the earth.
