Perseid Meteor Shower: How To See It In Colorado

ACROSS COLORADO – If you can catch only one meteor shower this year, it should be the Perseids. The celestial lightshow will peak overnight on Aug. 11-12 and Aug. 12-13. Whether you’ll be able to see it in Colorado depends on weather conditions, of course, but all signs are pointing to a spectacular show during the peak dates because the moon will only be a slim sliver of a crescent.

In normal years, the Perseids produce about 60-70 meteors an hour, and they’re typically rich in fireballs. In outburst years, such as 2016, the rate can more than double to around 150 to 200 meteors an hour.

To get the best views, find a dark sky. It may be your backyard if you live in a rural area; others may have to get a bit creative. If your state has dark sky preserves, plan to go there.

You can zoom in on your Colorado region on a map of global light pollution here. You might want to head east or southeast on highways I-70 or US 36 to find darker areas. If you drive up into the mountains, be aware that ambient light from towns along the I-70 corridor will interfere with your ability to see the meteor show. Deep in Rocky Mountain National Park you will find some of the darkest areas.

The Front Range is expecting clear weather tonight, with lows between 52-61 degrees in the plains areas, according to the National Weather Service. But the ozone level from auto exhaust and leftover wildfire smoke may make for a hazy sky.

NASA meteor expert Bill Cooke says outlandish claims often accompany reports of celestial events, including one last year that the Perseids would be the “brightest shower in recorded human history” and that meteors could be visible during the day.

While undeniably stunning, the Perseids never reach storm levels of thousands of meteors an hour, Cooke said, noting that the best Perseid performance on record was in 1993, when they flew at a rate of more than 300 meteors an hour.

But that shouldn’t dim your meteor-watching plans at all.

While both nights of the peak will be spectacular, look to Aug. 12-13 for the best meteor shower of 2018, Cooke said. The meteors begin flying after midnight and continue into the predawn hours.

“This year the moon will be near new moon, it will be a crescent, which means it will set before the Perseid show gets underway after midnight,” Cooke told Space.com. “The moon is very favorable for the Perseids this year, and that'll make the Perseids probably the best shower of 2018 for people who want to go out and view it.”

What are the Perseids?

The Perseids, which run annually from July 17-Aug. 24, are produced as the Earth passes through dust left behind by the comet Swift-Tuttle, discovered in 1862. The peak occurs when the Earth passes through the densest, dustiest area.

The pieces of debris heat up as they enter the Earth’s atmosphere and burn in a bright burst of light as they travel across the sky at about 37 miles per second. Most of the meteors are about the size of a grain of sand, so there’s little chance one will make it down to Earth as a meteorite.

The meteors fall between the constellations Perseus and Cassiopeia, but just look up and you should be able to see them from anywhere in the sky.

Be prepared to sit outside for a few hours. The longer you watch, the more you’ll see. It’ll take about half an hour for your eyes to adjust to the dark. Be sure to take along a comfortable camp chair, or maybe even a blanket so you can lay on the ground and get a panoramic view.

While you’re waiting for the Perseids, you should be able to see Mars until around 4 a.m. local time and Saturn, which will be visible until about 2 a.m. local time. Venus and Jupiter both set before the peak viewing hours for the Perseids, at 9:30 and 11 p.m., respectively.
