More Northern Lights are expected this week. Where will the best views be?

Time to look up again, skywatchers! If you live in certain parts of the United States and missed the northern lights, you may have another chance.

Large geomagnetic storms across North America have been caused by the sun's recent blasts of charged particles toward Earth, known as coronal mass ejections, or CMEs. The final and strongest CME is still speeding toward our atmosphere on Wednesday and is expected to provide another spectacular evening, according to the Space Weather Prediction Center of the National Oceanic and Atmospheric Administration.

About 18 states are partially or fully within NOAA's forecasted "view line" for the northern lights on Nov. 12. The view line indicates the southernmost point where the aurora could be seen on the northern horizon.

If the weather is clear, experts say parts of these states should be able to see the sky show: Alaska, Idaho, Illinois, Iowa, Maine, Michigan, Minnesota, Montana, Nebraska, New Hampshire, New York, North Dakota, Oregon, South Dakota, Vermont, Wyoming, Washington and Wisconsin.
