According to calculations by NASA, areas to the south and east of Los Angeles will see about 50% obscuration — the moon shrouding half of the sun — while much of the rest of the state will see around 25%.

L.A. is expected to see 48.6% obscuration around 11:12 a.m.

Because solar energy in space isn’t subject to factors like day and night, obscuration by clouds, or weather on Earth, it is always available.

Shetland is expected to have a 39% obscuration, which indicates how much of the sun's disc area is covered as a percentage.

“Smoke coverage was about the densest, most even all-day obscuration I can remember. Gray, gray, gray!”
