The moon will turn bronze red on Sunday night during a total eclipse, but San Diego will only see a glimpse of the spectacle.
Earth’s neighbor will be just above the horizon and will still be at twilight when the total eclipse begins at 8:29 p.m. Pacific time. If you have a good view of the western horizon, you will see the red color of the blood until 9:53 pm, after which it will fade.
explains NASA that a total eclipse occurs when the Sun, Earth and Moon are aligned so that the Moon passes into the shadow of the Earth.
The color red is due to the fact that the only light from the Sun that reaches the moon first passes through the Earth’s atmosphere, which disperses blue and passes red, a phenomenon that also produces red sunsets.
The eastern half of the United States and the whole of South America will have the opportunity to see every stage of the eclipse, but San Diego is very far west this time.
If you want to take a picture, NASA suggests using a tripod camera with exposures of at least several seconds
