To the rest of us, it's known as a partial solar eclipse.
Either way, it was quite the sight in the skies above Australia.
About 90 percent of the sun was blocked in Perth. And many astronomers converged on a small coastal town of Walkaway, about 200 miles away, where 99 percent of the sun was eclipsed, leaving a "ring of fire" in the sky.
Partial eclipses usually occur every one to two years, although the next is not expected until Dec. 4, 2002.
Experts warned against looking directly into the sky because of possible eye damage. That same advice was offered in aboriginal tribes, but for different reasons. They believe looking at an eclipse helps girls get pregnant.
