Friday the 13th solar storm could bring auroras to 18 US states this weekend - Live Science
Aurora Alert: Moderate Geomagnetic Storm to Affect Up to 18 U.S. States
As the summer solstice approaches, skywatchers in up to 18 U.S. states are in for a treat – literally! A moderate geomagnetic storm is expected to rock Earth's magnetic field, starting on Friday, June 13. This phenomenon can lead to breathtaking displays of the aurora borealis (northern lights) and aurora australis (southern lights).
What is a Geomagnetic Storm?
A geomagnetic storm occurs when the solar wind, a stream of charged particles emanating from the sun, interacts with Earth's magnetic field. This interaction can cause disturbances in the magnetic field, leading to spectacular displays of the aurora.
The Science Behind Auroras
Auroras are created when charged particles from the solar wind collide with atoms and molecules in our atmosphere. The collisions excite these particles, causing them to emit light at specific wavelengths, which we perceive as the aurora. The color of the aurora depends on the energy of the particles and the altitude at which they collide.
The Storm and Its Implications
The moderate geomagnetic storm expected on Friday is predicted to affect up to 18 U.S. states, including:
- Alaska: High levels of activity are expected, with frequent sightings of the aurora.
- Washington, Oregon, and Northern California: Moderate to high activity is expected, with a good chance of seeing the aurora.
- New York and Pennsylvania: Some activity is expected, but it's likely to be less intense than in the western states.
- Michigan, Wisconsin, and Minnesota: Moderate activity is expected, with possible sightings of the aurora.
When and Where Can I See the Aurora?
The best time to see the aurora depends on the location and the intensity of the storm. Here are some general guidelines:
- Northern states: Look for the aurora between 10 PM and 2 AM, when the solar wind is most active.
- Western states: Expect the aurora to be visible around midnight to 4 AM.
Tips for Viewing the Aurora
To increase your chances of seeing the aurora, follow these tips:
- Find a dark location: Get away from city lights and find a spot with minimal light pollution.
- Dress warmly: It can get chilly while waiting for the aurora to appear, so dress in layers.
- Bring a camera: Capture the moment with your camera, but be aware that long exposures may not capture the full effect of the aurora.
Conclusion
The moderate geomagnetic storm on Friday promises to deliver breathtaking displays of the aurora borealis and aurora australis. Whether you're in Alaska or upstate New York, get ready for an unforgettable experience. Grab your camera, bundle up, and head outside to witness the celestial spectacle!
