The “Aurora Borealis” also known as The Northern lights are expected to shine over the U.S. as geomagnetic activity driven by solar coronal holes will lead to an explosion of color in the sky (PA)
The diameter of the seeing disk, most often defined as the full width at half maximum (FWHM), is a measure of the astronomical seeing conditions. It follows from this definition that seeing is always a variable quantity, different from place to place, from night to night, and even variable on a scale of minutes.
States best positioned within the aurora viewing line include: Alaska. Washington. Idaho. Montana. North Dakota. Minnesota. Michigan. Wisconsin. The auroras may also be "highly active" in parts of ...

See photos as a powerful geomagnetic storm watch put the aurora borealis on full display across the US and Europe on Friday night.
Aurorasaurus contains a real-time map that displays the location of tweets that talk about auroras and have geolocation data. [2] Users then verify if the tweets indicate a sighting. [ 6 ] Aurorasaurus also plots a "view-line" onto the map which shows users the predicted area in which they can see the aurora according to the National Oceanic ...
For the best viewing, the center recommends that it be very dark. Get away from city lights and avoid trying to see them on the night of a full moon. The best time to view the aurora is within an ...
Hence, when conditions are right, a rainbow always appears in the section of sky directly opposite the Sun. For an observer on the ground, the amount of the arc that is visible depends on the height of the sun above the horizon. It is a full semicircle with an angular radius of 42° when the sun is at the horizon.
