In Maine, vision testing is required at the first renewal after driver's 40th birthday, then at every second renewal until age 62, and thereafter at every renewal. In Oregon, vision testing is required every 8 years for drivers 50 and older. In Illinois and New Hampshire, applicants 75 and older must take a road test.
Bottom line: When charged particles from the sun strike atoms in Earthâs atmosphere, they cause electrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights.
The CME is expected to induce a geomagnetic storm that will cause the northern lights show. Outten said that this CME is the second of a two-hit punch, as another had hit the Earth's atmosphere on Thursday. There will be a pretty good chance to see the northern lights [Friday] because of the first geomagnetic storm Thursday night, Outten said.
