Tomorrow morning, you’ll get the chance to see one of the rarest types of lunar eclipse, called a selenelion or horizontal eclipse. But you have to be quick, because you’ll only have between two and nine minutes to catch this crazy light trick.
Most of the time, a lunar eclipse will occur well before sunrise, but that won’t be the case on Wednesday morning. The Earth will pass between the sun and moon, eclipsing the moon in the process, which will begin at 6:25 a.m. EST and last through sunrise, but only on the east coast.
That means during a brief window, in this case between two and nine minutes, people on the east coast of the country will be able to see the sun rise and moon set at the exact same time. This rare event is referred to as a selenelion or horizontal eclipse.
