The so-called "California Henge" happens twice a year when the sun falls perfectly above the Bay Bridge in between California and Gough Street in San Francisco.
Photos below show amazing photos taken by ABC7 News Executive Producer Mark Stephens.
It's somewhat similar to England's Stonehenge, which was built to align with the sun during winter and summer solstices.
California Henge is supposed to happen Saturday through Monday before 7 a.m.
If you miss it this weekend - don't worry. The astronomical phenomenon will happen again this September.
