Stargazers are in for a treat this weekend. The NOAA (National Oceanic and Atmospheric Administration) has issued a geomagnetic storm this weekend. This means that the northern lights, also known as auroras, might be visible. This event coincides with the peak of the Perseid meteor shower.
The geomagnetic storm watch is in effect from August 9 to August 11. This is due to heightened solar activity. Three coronal mass ejections (CMEs) from the sun are heading towards Earth. These CMEs are expected to arrive late on August 9 and again by mid to late August 11.
What is a Geomagnetic Storm?
A geomagnetic storm occurs when solar wind from the sun interacts with Earth’s magnetic field. This can cause disturbances in the magnetosphere. These disturbances can create beautiful displays of light in the sky.
These lights are known as the northern lights or aurora borealis in the Northern Hemisphere. In the Southern Hemisphere, they are called the southern lights or aurora australis.
Why This Weekend is Special
This weekend is special because the geomagnetic storm coincides with the Perseid meteor shower. The Perseid meteor shower is one of the most popular meteor showers of the year.
It peaks around August 11 and before dawn on August 12. During this time, you can see up to 100 meteors per hour.
Where to See the Northern Lights
If the predicted moderate G2 conditions are met, auroras might be visible as low as New York and Idaho. This means that people in northern and upper Midwest states have a good chance of seeing the northern lights.
Even if the geomagnetic storm conditions are not reached, a strong enough solar substorm can also create impressive auroras.
How to Watch the Perseid Meteor Shower
To watch the Perseid meteor shower, find a dark place away from city lights. The best time to watch the meteor shower is after midnight and before dawn.
Lie down on a blanket or a reclining chair. Look up at the sky and be patient. It takes about 30 minutes for your eyes to adjust to the dark.
Safety Tips
Remember to stay safe while watching the northern lights and the Perseid meteor shower. Dress warmly as nights can be cold.
Bring a blanket or a chair to sit on. Avoid using bright lights as they can ruin your night vision. If you are driving to a dark location, be careful on the roads.
