On May 17, a mysterious white streak surprised many across the U.S. skies during a powerful surprise aurora storm. This rare event happened when a strong geomagnetic storm caused vivid aurora borealis displays far south of their usual range. As the colorful northern lights danced across the sky, a bright, glowing streak suddenly appeared, sparking curiosity and many questions. Was it a meteor, a satellite burn, or something else? Scientists later connected this glowing trail to a methane-fueled rocket maneuver during a satellite orbit insertion. This unexpected sky event reminded everyone how space and atmospheric phenomena can create moments of awe and wonder in the night sky.

The night sky was glowing green, pink, and purple due to a strong geomagnetic storm. Then, something strange appeared—a bright, straight mysterious white streak that lasted several minutes. Unlike a shooting star or meteor, this light didn’t flash and vanish quickly. It stretched far across the sky and slowly faded.
Many people took pictures and shared them online. One famous photo came from Mike Lewinski in Crestone, Colorado. His image, which shows the white streak alongside the photos of aurora, quickly spread on X (formerly Twitter). Some sky watchers thought the light was a satellite deployment or a rocket re-entry, while others asked if it was a new type of atmospheric phenomenon.
Where and When Did the Streak Appear?
The streak appeared on the evening of May 17 during the height of a surprise aurora caused by a strong coronal mass ejection (CME). This May 17 aurora storm brought the aurora borealis as far south as Utah and New Mexico—places that rarely see the northern lights.
The bright white line was reported in multiple states across the Four Corners area. The streak was most visible around 11 PM local time and appeared high in the sky, visible to the naked eye. According to observers and space weather trackers, the streak crossed over the U.S. skies at an altitude of 155 miles (250 km), well above commercial airplane height but below typical satellites.
Was It Linked to the Aurora Storm?
While the mysterious white streak appeared during the May 17 aurora storm, it was not directly caused by the aurora borealis or the filament eruption from the Sun. However, the geomagnetic storm played a big role in making the sky darker and more colorful than usual, which helped people notice the rocket streak more easily.
The storm was caused by a coronal mass ejection (CME) from a filament eruption on the Sun’s surface. This solar event released charged particles that hit Earth’s magnetic field, creating stunning auroras. But the streak itself came from a different source: a methane-fueled rocket.
Possible Explanations: Fireball, Satellite, or Rocket?
At first, sky watchers suggested it could be a fireball, a satellite burn, or even part of the STEVE phenomenon. But soon, space scientists found the real reason. The light was from the upper stage rocket of the Zhuque-2E, a methane-fueled rocket launched by Landscape, a Chinese space company.
The rocket had launched earlier that day from the Jiuquan Satellite Launch Center (JSLC) in China. The streak people saw was caused by a fuel dump during satellite orbit insertion. This bright line formed as leftover fuel vented out in space, creating a glowing trail in the upper atmosphere.
Here’s a comparison table of possible explanations:
| Phenomenon | Description | Seen in Event? |
|---|---|---|
| Fireball | Fast, bright meteor burning in sky | No |
| Satellite Re-entry | Broken satellite burning on return | No |
| Rocket Upper Stage Burn | Fuel dump during orbital maneuver | Yes |
| STEVE Phenomenon | Sky glow caused by charged particles | No |
What Experts and NASA Say About the Streak
Space experts quickly confirmed the source. Jonathan McDowell, a known space scientist, posted on X (formerly Twitter) that the streak matched the path of the Zhuque-2 rocket. He explained that this kind of space science payload maneuver is common during satellite deployment.
NASA scientists agreed that it wasn’t dangerous and is a known part of rocket operations. According to Spaceweather.com, these events often happen but go unnoticed unless the sky is very clear—or during special events like the May 17 aurora storm.
Social Media Reactions and Eyewitness Accounts
Many people shared what they saw. “I’ve never seen anything like that,” wrote one user from Colorado. Another posted, “First time seeing northern lights, and then this mystery streak appeared!”
Mike Lewinski became a popular name after his photo of the aurora and the rocket streak went viral. Others in the Four Corners area described the event as “peaceful,” “otherworldly,” and “like a comet leaving a ghost trail.”
Online forums also buzzed with talk about rocket re-entry, space debris, and questions about space tracking.
Similar Past Incidents in US Skies
This isn’t the first time something like this has happened. In the past, rocket launches by SpaceX and other companies have caused glowing trails. For example, a Falcon 9 launch in 2023 left a rocket re-entry glow seen from California to Arizona.
In 2018, a mysterious spiral light seen in the sky turned out to be a satellite deployment burn from a Russian rocket. These events are often seen in the western U.S. skies, especially after dusk.
Such atmospheric phenomena may seem rare, but as space launches increase, sightings like these may become more common.
How to Tell the Difference Between Satellites, Fireballs, and Rocket Trails
Skywatchers often wonder how to tell what they’re looking at. Here are simple ways to tell them apart:
| Feature | Satellite | Fireball | Rocket Fuel Dump |
|---|---|---|---|
| Speed | Slow and steady | Very fast | Slow fading trail |
| Brightness | Moderate | Very bright | Bright, then dim |
| Direction | Steady path | Sudden streak | Often curved arc |
| Duration | 2-5 mins | 1-3 seconds | 5–15 minutes |
Apps like Heavens Above or SkySafari can help you track real-time satellite deployments or radar spacecraft. With practice, anyone can learn to spot the difference.
Could This Happen Again? What to Watch for in Future Sky Events.
Yes, events like this can happen again. With more methane-fueled rockets, satellite orbit insertions, and space science payloads being launched from many countries, people in the U.S. skies may see more rocket re-entries and fuel dumps.
To stay informed, skywatchers can follow websites like Spaceweather.com, subscribe to alerts from NOAA, or track missions from the Jiuquan Satellite Launch Center (JSLC) and other global launch sites.
If there’s another surprise aurora, be ready—something unexpected may light up the sky again.
Final Thoughts: Awe, Curiosity, and Science in the Night Sky
The mysterious white streak seen during the May 17 aurora storm reminded many people of the wonder of the night sky. Events like this blend beauty and science. The colors of the aurora borealis, the stillness of Earth, and the rush of a rocket streak all came together for a few magical minutes.
Thanks to fast online sharing, experts like Jonathan McDowell, and websites like Spaceweather.com, the mystery was solved quickly. But that doesn’t take away the joy and awe many felt. In a world filled with screens and noise, sometimes it takes a surprise sky event to get people looking up again.
