If overcast weather doesn’t get in the way, stargazers in a portion of the United States will have the unique chance to witness the northern lights this weekend.
The northern lights, which light up the night sky above the northern United States, will provide a unique celestial spectacle to start the weekend.

The sun has been launching large clouds of charged particles, called coronal mass ejections (CMEs), towards Earth for the last several days. The Northern Hemisphere will see the aurora borealis flare, and the Southern Hemisphere will see the aurora australis ignite. This is because they will strike Earth’s magnetic field.
The Northern Lights: What Are They?
The aurora borealis, often known as the northern lights, are dazzling, whirling curtains of light that can be any hue from green to pink to crimson in the night sky.
It is brought on by charged solar particles colliding with atmospheric gases. The Earth’s atmosphere’s various gases are electrified by the charged particles, which is why the colors appear.
In the Earth’s atmosphere, nitrogen and oxygen are the two most prevalent gases. Atoms of oxygen shine green, the hue most commonly associated with the Northern Lights; atoms of nitrogen generate purple, blue, and pink light.
Large-scale particle clouds known as “coronal mass ejections” from the Sun produce the most spectacular auroras.
Where are the northern lights visible?
The northern United States was able to see the dancing of the celestial lights, since CMEs, which typically cause the aurora above Canada, were considerably larger than normal.
Because this is when the CMEs are expected to arrive at Earth, the aurora may be viewable to the unaided sight as far southern as Virginia, Missouri, Colorado, and the northern part of California on the night of Friday into the early hours of Saturday, according to NOAA’s Space Climate Prediction Centre (SWPC).
Long-exposure photography allows photographers further south to catch the aurora even if they are unable to see it with their eyes.
Stronger than the aurora outbursts that occurred last spring and allowed observers to view the northern lights from as far south as the state of North Carolina and Oklahoma, the projected light display is expected to be spectacular.
The northern Plains as well as Pacific Northwest are likely to have the finest viewing conditions, with mostly cloud-free skies providing excellent views of the sky at night.
The Ohio Valley may be the only area where some aurora views are possible due to cloud gaps, but clouds will be a major problem for people in the Northeast and parts of the Midwest.
People have to go to a place with extremely minimal light pollution and face north in order to observe the aurora. It might show up above the horizon as a red or green light.
More opportunities this weekend
Due to the sun’s busy week of sending many coronal mass ejections (CMEs) towards Earth, there is a chance that the northern part of the US may see aurora activity on Saturday night provided certain circumstances are met.
The SWPC has released its first G4 watch since 2005 in response to the anticipated effects of the CME. Although Friday night is expected to be the peak of aurora activity, the geomagnetic storm may last into Saturday night, however there may not be as much aurora activity thereafter in the weekend.
Normally, throughout a lot of Canada as well as Alaska, these phenomena would likewise result in breathtaking displays of whirling colors, but there’s a catch: daylight.
As the June solstice approaches, areas in northern Canada and Alaska, including Fairbanks and Anchorage, are experiencing exceptionally brief or non-existent twilight periods. In these regions, although the sun sets daily, it never fully dips below the horizon, resulting in nights that are not completely dark.
