Finn's Take· TL;DRA series of intense solar eruptions has set the stage for a spectacular celestial show across the western United States this weekend. A G3 – Strong Geomagnetic Storm Watch is in effect for June 4 and 5, 2026, following three significant solar flares from Active Region 4455. The solar outburst included an M9.3 flare at 01:36 UTC, an M7.7 flare at 07:00 UTC, and an X1.0 flare at 11:28 UTC on June 3.
CME passage would likely continue into the evening and possibly overnight hours of June 5. The timing of these coronal mass ejections—massive bursts of plasma and magnetic field from the sun—creates prime conditions for aurora viewing across much of the northern United States. SWPC ENLIL model shows two Earth-directed CMEs interacting en route to Earth, with the later, faster CME catching up to the earlier structure and producing a combined solar-wind enhancement near Earth late on June 4.
The northern lights "may be visible" in northern Utah and are also "possible" across the rest of the state this time around, according to a map produced by the Space Weather Prediction Center. While northern regions of the state have the best chances, some areas might be able to see it with a camera, if not the naked eye. This represents a significant opportunity for Utahns who missed previous aurora displays throughout the year.
The broader western region is well-positioned for viewing. Most of Idaho and Wyoming may also see the spectacle, with it likely across northern Idaho, along with most of Washington and Montana. For those willing to travel slightly north, the viewing prospects become even more promising. The storm's strength could potentially push the aurora visibility line further south than usual, though the watch extends into Friday, but the Geophysical Institute projects lower activity levels by the time the sun sets across the West.
The best viewing opportunities will likely occur Thursday and Friday nights, with optimal conditions requiring dark skies away from urban light pollution. Late spring is not the best time for northern lights viewing because of later sunsets and fewer hours of darkness. However, if a geomagnetic storm becomes strong to extreme, the northern lights can put on a good show and even appear as far south as Florida.
Photography enthusiasts should prepare their equipment, as cameras often capture aurora details invisible to the naked eye. To view the lights, skygazers should get away from light pollution by turning off outdoor lights or moving away from city lights. If nothing appears to the naked eye, a smartphone camera may provide better results. The current forecast suggests peak activity could arrive during prime viewing hours after sunset.
An aurora borealis, or northern lights, occurs when solar material from the sun hits Earth's magnetic field, creating a colorful display in the sky. Under G3 – Strong conditions, auroras may be seen at lower-than-usual latitudes, including across parts of the northern United States, when viewing conditions are favorable. This particular storm represents one of the strongest alerts issued this year.
While the storm promises visual rewards, it may also cause minor technological disruptions. The National Weather Service's Space Weather Prediction Center issued a watch for a G3 (strong) geomagnetic storm earlier this week, predicting strong solar activity on Thursday and Friday that increases the odds of magnetic field disruptions. These effects are typically minimal and manageable for most infrastructure systems.
As solar activity continues to intensify during this solar maximum period, more opportunities for aurora viewing may emerge throughout the year. This weekend's event offers a reminder of our planet's dynamic relationship with the sun and provides a rare chance for western residents to witness one of nature's most breathtaking displays without traveling to polar regions.
