Early risers will have the best chance of seeing Wednesday's super blue blood moon.
The best time to observe the moon will be from 6:15 to 6:30 a.m. Wednesday throughout Northwest Indiana and northern Illinois, according to the National Weather Service. It will be the brightest moon in nearly 69 years.
Passing clouds are expected, but a narrow window of clearing could occur about sunrise Wednesday, forecasters said.
Viewers can expect to see a moon about 14 percent larger in diameter and about 30 percent brighter than when it's at its furthest distance from the earth. It won't be as big and bright again for another 18 years.
According to the astronomy website earthsky.org, the term supermoon entered usage five years ago when the closest full moon fell on March 19, 2011. The scientific term is perigee full moon.
