Depending on the weather, the astronomy class may host a lunar eclipse-viewing event for students from 10:30 p.m. on Monday, Dec. 20, according to science teacher Josh Bloom.

“Unfortunately, the weather does not look like it is going to cooperate with us,” Bloom said. “However, should it clear up we will meet from 10:30 p.m. to 12 a.m.”

Though the event is integral to the astronomy class, all students are welcome, according to Bloom.

“It is affiliated with the class, but not officially hosted by the school,” Bloom said. “It is a gathering anyone is invited to.”

Lunar eclipses happen when the Moon passes through a section of the shadow cast by Earth, according to NASA astrophysicist Fred Espenak’s website.

“A lunar eclipse occurs when the Full Moon passes through the Earth’s shadow, allowing us here on Earth to see the Earth’s shadow move across the face of the Moon blocking the light of the Sun that normally makes the Full Moon shine as it does,” Bloom said.

Espenak also explains on his website that lunar eclipses are safe to watch, without protective filters, and can be seen without a telescope.

Students should meet for the event at the Hill located at west end of California Ave on Monday evening, Bloom said.

“Heading south on El Camino make a right on California Ave instead of your normal left into the downtown area, go all the way to the end, park, and there is a trail that leads you up to the hill starting at the very end of California Ave,” Bloom explained.

This total lunar eclipse is positioned optimally for viewers in North America, according to NASA’s lunar eclipse webpage.

Despite expected rain on Monday, Bloom stays positive and hopes he can enjoy the lunar eclipse with his students.

“I hope the weather clears,” Bloom said. “Ancient people used to believe they were frightening omens foretelling violent events to come. Today we know better, and can enjoy them with fascination instead of fear.”
