Sure, we know we've been talking a lot of talk about Sunday's Bay to Breakers blowout. But now we've got proof to show that Sunday's going to be special. Celestial proof. Believe it or not, the planets are literally aligning to make Sunday even more awesome.

Beginning at around 5:16pm on Sunday evening, and reaching its fullest eclipsedness at 6:33pm, this solar eclipse will see the Moon partially obscure the Sun, leaving a rare "ring of fire" effect (cue the Johnny Cash, please). We astronomy nerds know that the Moon is at its furthest point away from us, which is why it won't cover the entire sun and leave us in total, terrifying darkness, but a flaming Eye of Mordor in the sky is arguably even more badass. The eclipse will only be visible in the Western states, since the sun will have set on the rest of the country (sorry we're not sorry, Eastern U.S.).

The ring of fire won't cast a literal shadow over your evening, but it will provide a visual treat the likes of which the U.S. hasn't seen in 18 years (do you remember looking through your pinhole projectors on the playground in 1994?). NASA's eclipse expert has given it a '9 out of 10' in terms of visual spectacles, which is amazing because a) there's such a thing as a NASA eclipse expert and b) he judges eclipses like an Olympic gymnastic competition.

As beautiful as it may be, remember that staring directly at the Sun is a bonehead move that can result in blindness, so take precautions before you look skyward (the best way to do this is, believe it or not, to make a pinhole projector, 4th grade style).
