CNN — For a brief moment early Tuesday morning, eyeballs turned upward to the moon, not downward on electronic devices.
Crowds worldwide stepped outside in the wee hours to catch a glimpse of the coppery red moon as it crossed the earth's shadow. We're talking about the "blood moon".
In Los Angeles, the chance to view the total lunar eclipse lured thousands to the Griffith Observatory. Families spread out blankets on the grass to take in views from dozens of telescopes set up like a stand of small trees.
If you missed it, there will be more opportunities. It's the first in a series of four consecutive total lunar eclipses known as the tetrad.
The phenomenon will repeat itself three more times in six-month intervals ending in September 2015.
