Wake up early or stay up late: If skies are clear, you could see the bright full moon turn a reddish hue during a total lunar eclipse early on the morning of April 15.

Lunar eclipses are safe to watch with the naked eye. Fred Espenak, astronomer and noted eclipse expert (MrEclipse.com) says the eclipse could take on “a dramatically colorful appearance, ranging from bright orange to blood red.”

During a lunar eclipse, the Earth quite literally sits between the sun and the moon, blocking sunlight from reaching the usually radiant full moon. Look to the southern sky. The first partial eclipse phase starts at 1:58 a.m., when the moon enters Earth’s umbral shadow.

In the southwestern sky, the total eclipse phase begins at 3:07 a.m., with the middle of totality at 3:36 a.m., according to Espenak. Totality ends at 4:25 a.m., when the moon perches on the shadowy umbral-penumbral fence. That’s the second partial eclipse phase, and it ends at 5:33 a.m. Totality will last about 77 minutes.

Next to the moon, you might spy Spica, a first-magnitude star in the constellation Virgo. The bright reddish Mars hangs to the right of the moon.

This eclipse represents the first of four total lunar eclipses in a row. That kind of series is known as a tetrad — with the next three occurring Oct. 8, 2014; April 4, 2015; and Sept. 28, 2015. Tetrads happen occasionally, as we’ll see only eight in this century. Our last tetrad was in 2004 and our next will be in 2032-33.

April nights open with Jupiter high in the west-southwest (Gemini constellation) at a bright -2.2 magnitude. Mars (-1.4 magnitude, bright) ascends around 9 p.m. Up all night, it reaches opposition April 8. Saturn (zero magnitude, bright) follows Mars, rising in the east-southeast around 10:40 p.m. now. Venus (-4.3 magnitude, very bright) reigns in the eastern morning sky, an hour or so before sunrise.
