News Summary
A powerful coronal mass ejection is set to cause geomagnetic activity, potentially allowing residents of Texas, including San Antonio and Austin, to witness the northern lights. The Space Weather Prediction Center has verified the event, which may bring visibility of the aurora borealis to lower latitude regions. While urban light pollution may limit views, ideal conditions could lead to stunning sightings. The storm might also impact technology services, and local companies are prepared to manage any disruptions. Texan skywatchers should keep an eye on aurora forecasts and be ready for this rare celestial display.
San Antonio, Texas – A significant coronal mass ejection (CME) occurred early on June 1, 2025, at 12:23 a.m. CDT, leading to expectations of geomagnetic activity that may result in the spectacular display of the aurora borealis, or northern lights, visible in parts of Texas and other lower latitude areas of the U.S. The Space Weather Prediction Center (SWPC) has confirmed the CME and indicated that its effects could extend into June 2.
The anticipated aurora display, first observed at 1:23 a.m. EDT on June 1, may allow residents in Texas, including cities like San Antonio and Austin, to catch a glimpse of the natural phenomenon. Although visibility may be limited, especially in urban areas, it is possible that sensitive phone cameras could capture the breathtaking lights if conditions are right.
Previously, San Antonio enjoyed sightings of the northern lights during stronger CME events in May and October 2024. The SWPC has predicted that the intensity of the aurora may be strongest in northern regions of Texas, but conditions for viewing can fluctuate due to local cloud cover.
Additionally, the SWPC has warned of a slight chance of minor technological impacts as a result of the geomagnetic activity. These impacts could include interruptions to GPS and satellite services, and there is a minimal risk that certain power grids might be affected. However, local utility companies have been informed and are equipped to manage any necessary adjustments to minimize disruptions.
The geomagnetic storm associated with this CME has been classified on a scale from G1 to G5, with G4 categorized as severe. Factors contributing to the anticipated activity include high-speed solar winds from coronal holes paired with the June 1 CME. Complicating matters, a second CME is expected to arrive late on June 2, which may extend the storm’s impacts. Furthermore, an additional smaller CME is anticipated on June 3-4, potentially fostering further auroral activity.
While some previous stronger CMEs last year led to minimal disruptions, the unusual makeup of this solar storm, stemming from multiple CMEs, renders its effects less predictable. In this dynamic environment, residents are encouraged to keep an eye on aurora forecasts from NOAA, which includes an aurora dashboard providing real-time information about potential sightings as well as a 30-minute forecast for viewers.
For those eager to witness the northern lights, the best hours for viewing are typically from 10:00 p.m. to 2:00 a.m. local time. Enthusiasts are advised to minimize exposure to city lights to enhance viewing conditions. Community members are also encouraged to capture their experiences and share images or videos through platforms like KSAT Connect.
As the ongoing solar season remains active, increased solar activity continues to promise the potential for additional aurora sightings. As geomagnetic conditions fluctuate, Texan skywatchers might find themselves captivated by this awe-inspiring celestial event.
