The Northern Lights It may be visible again this weekend in unusual places in America and Europe where it is not common for this phenomenon to occur so far south, after last night it surprised those who observed it in countries such as Mexico and Spainwhere it does not usually appear.
He Space Weather Prediction Center The United States predicts that it can be seen with intensity on Saturday nights, especially, and on Sunday in areas of countries such as Canada, USA and Russia.
The prediction of this center of the National Administration Office Oceanic and atmosphere of the United States is that the phenomenon reached its maximum intensity, nine out of nine, in some hours of Saturday night in those areas.
The geomagnetic conditions in the atmosphere of the northern hemisphere are the most extreme recorded since October 2003, resulting in the aurora is seen in places where it is very rare.
This scientific agency issued an alert on the G5 scale, the maximum on its scale, after several days of intense solar activity that increased on Friday, as a geomagnetic storm That level can cause problems in the electrical grid and navigation, radio and satellite operations.

From the Canary Islands in Spainoff the African coast, and the megalithic monument of Stonehenge in the United Kingdom to Sonora in Mexico and Los Angeles and Chicago in the United States, numerous social media users shared last night images of skies illuminated with pinkish and greenish tones.
The State Meteorological Agency in Spain confirmed that “they are observing polar auroras very low latitudes of the northern hemisphere”, which may be repeated in the country’s skies this weekend due to this strong geomagnetic storm on Earth.
According to the World Meteorological Organizationconsists of a luminous phenomenon in the upper layers of the atmosphere with shapes such as arcs, bands or curtains, at an altitude of between 90 and 150 kilometers, due to the interaction between the solar wind and the Earth’s magnetic field.
Despite the great expectation they generate, the northern lights still present many unknowns for science.
New northern lights expected outside the poles
To help solve them, a balloon expedition of four Spanish scientists begins next Monday with the aim of recording the northern lights from the atmosphere, at about 30 kilometers altitude, starting from the frozen lake of Inari (Finland).
This year the Sol registers a maximum of activity in a cycle of eleven years, and this month of May, because it is close to the equinox, is when, due to the axis of rotation of the planet, greater penetration of solar wind in the Earth’s magnetosphere.
