People in central Illinois are reporting a giant boom that shook a whole apartment complex about three hours ago on May 23, 2014. Some have seen flashes (green and orange) in the sky other nothing. In parallel, at least three mystery booms were heard and shook houses and windows in southern Louisiana. Some in the same thread reports booms in Virginia and Pennsylvania, where 3 flash of lights were observed striking through the sky.
These mystery booms and this intense sky activity is most probably related to the first ever Camelopardalid meteor shower TONIGHT!
