Once in a blue moon, a lunar eclipse occurs during a blue moon.
That rare phenomenon will happen early Wednesday morning when the lunar eclipse, which will be partially visible in Ottawa's western sky, falls on the second full moon of the month, known as a blue moon.
For skygazers the effect will be what astronomers call "a super blue blood moon."
"Light refracted through our atmosphere turns the lunar surface red, much like we see red sunsets," said Ottawa astronomer Gary Boyle.http://www.cbc.ca/news/canada/ottawa/ottawa-stargazers-look-up-for-partial-lunar-eclipse-1.4506522
