The last aurora borealis that has been witnessed was in Florica on Thursday — in specific, in the southern area of Florida—. The pictures that were taken show the entire sky lit up in red and purple. Area like New York and Chicago have shown some brightly lights.

The strong geomagnetic storm that was the origin of this show has subsided, according to the National Oceanic and Atmospheric Administration. However, in some parts of the U.S. the possibility of seeing the northern lights at nights. Down below we will provide you all the information that you must know in order to be a witness of this amazing spectacle.

All you must know where the northern lights will be visible at night.

In some parts of the northern U.S. the northerns lights will be visible, according to the NOAA Space Weather Prediction Center’s aurora forecast. Canada and Alaska are the areas in which the aurora will be visible. In the case the weather conditions are favourable, the northern lights can also be seen from 620 miles, NOAA explained.

Parts of Idaho, South Dakota, Minnesota and Wisconsin, seeing the lights is possible on Friday nights. Moreover, in the case you were on the East Coast, the aurora might appear in northern New York and some parts of Vermont and New Hampshire. Areas of Maine may see the northern lights too.

When it’s dark outside, the lights will make their appearance in the north. In the situation that you are not able to see them, the phone camera or another digital device, it makes easier to see the appearance of the lights.

The perfect timing to see the northern lights

Just after sunset or just before sunrise are the best time and it is when they are most visible, NOAA commented.  Unfortunately, the aurora won’t be visible during the dark. The best viewing experience is settle when the sky is cloudless and dark with little artificial light.

The reason of the high visibility of the auroras

The sun’s activity has been incredibly over the last months, unleashing some of coronal mass ejections from its surface, according to CBS Boston. Due to this happening, multiple auroras showed up in the sky.

The Thursday’s stunning skies caused by the geomagnetic storm is subsiding at the current time, CBS Boston reported. This shows that the chance of the appearance of auroras on Friday will be less, but in the future the chances are also possible.

The forecast coordinator with the Space Weather Prediction Center, Shawn Dahl, told to CBS Boston the intensity’s lights have been higher dure to the 11-year’s solar cycle.  In addition, he also said that this fact means that the sun is at the moment twisted-up mass of strong magnetic fields and some of the there are localized.

The northern lights’ causes

Through the interaction of the northern lights between the sun’s solar wind and Earth’s protective magnetic field, according to NOAA. Both phenomena result in geomagnetic storms and the increased geomagnetic activity.

When the geomagnetic activity increases, the odds of witness the aurora are better. The increment of geomagnetic activity also show the aurora will become even brighter, NOAA explained.

The moderate solar wind creates the aurora so that why the appearance of a week aurora from somewhere on Earth is more common. The best spots to see these auroras of this kind is getting close to the planet’s poles —such as Greenland or southern Argentina—.
