But be prepared to come early and walk a long distance from parking, warned observatory officials. The nearby Greek Theatre is holding a concert (the Catch a Fire tour celebrates what would have been Bob Marley’s 70th birthday year) and vehicle and foot traffic is expected to be extremely heavy around the venues.

Those heading to the observatory are also asked not to bring personal telescopes or lawn chairs. A supply of lawn telescopes and binoculars will be provided and the eclipse should be easily viewed with the naked eye, officials said.

A lunar eclipse occurs when the Earth’s shadow falls on the moon as it moves between the moon and the sun. The coppery reddish color of the lunar face has given rise to its description as a “blood moon.”
