How to catch a rare sighting of this emerald in the sky

Light pollution will make comet hard to see in L.A., but there are spots to sky gaze.

A once-in-50,000-years green comet is passing through our solar system, but if you live in Los Angeles you’re unlikely to be able to spot it for yourself.

C/2022 E3 (ZTF) will be closest to Earth on Feb. 1 and may be “only just visible to the eye in dark night skies,” NASA said.

Discovered at the Zwicky Transient Facility at San Diego County’s Palomar Observator­y in early March, the comet has been growing brighter as it approaches its perigee, or the closest point in its orbit to Earth.

When the time is right, especially on the mornings of Jan. 31 through Feb. 2, those wishing to see the comet may want to leave the lightpollu­ted Los Angeles Basin.

“I’m quite doubtful that you’re gonna see it from downtown Los Angeles,” said Steven Flanders, public affairs coordinato­r for Palomar Observator­y. “The background sky is so bright there.”

The comet should be “to the left of Polaris and about the same height,” he said, referring to the North Star. He was able to see its green glow Thursday morning through binoculars from the secluded observator­y.

The comet releases carbon gas as it approaches the sun and warms up, causing the green glow effect.

Cities including Los Angeles switched to LED lights in recent years to save energy and money, worsening light pollution.

For celestial viewing, UCLA physics and astronomy lecturer Art Huffman suggests the following sites:

8 Joshua Tree National Park.

8 Death Valley National Park.

8 Red Rock Canyon State Park east of Bakersfiel­d.

8 Anza Borrego Desert State Park .

Three of those four parks are listed on the Internatio­nal Dark Sky Assn.’s list of dark sky parks, selected for “possessing an exceptiona­l or distinguis­hed quality of starry nights,” per the associatio­n’s website. Two Southern California towns, Borrego Springs and Julian, are on the list of dark sky communitie­s.

One can watch the comet virtually via a livestream provided by the Virtual Telescope Project.
