Northern Lights May Appear Across North America Tonight
A burst of energy from the Sun is heading toward Earth.
It can make Earth’s upper atmosphere glow, creating the northern lights.
The lights may be visible in Canada and parts of the United States on Thursday night and early Friday.
The exact places depend on how strong the storm becomes and whether skies are clear.
People have a better chance of seeing them away from bright city lights.
Let your eyes adjust in the dark for about 20 minutes.
A phone camera may capture colors that look faint to your eyes.
Night Mode or a longer exposure can help, especially if you keep the phone still.
A solar flare-triggered coronal mass ejection is expected to create geomagnetic storm conditions overnight Thursday into early Friday.
The aurora may begin around 11 p.m. ET Thursday, with another possible surge around 5 a.m. ET Friday.
Canada is forecast to have potential visibility across all ten provinces and three territories if skies are clear.
In the United States, visibility is expected across northern states, with possible farther-south sightings if the storm reaches moderate G2 strength.
The article recommends finding dark skies and using a phone’s Night Mode or a 3-to-5-second exposure to photograph faint auroras.
