After a display of northern lights on Monday evening, there can be another good luck to see them tonight

Skywatchers was treated to a moderate light in the North Lights on Monday evening. For those who missed, there is still a chance that they are visible again this evening, with a stronger geomagnetic storm forecast.

The National Oceanic and Atmospheric Administration (NOAA) (SWPC) prediction prediction (NAAA) prediction center (NOAA) provides for a strong geomagnetic storm. (Monday was considered moderate.)

The sun was quite active, with many solar spots on its surface. Sometimes these spots unleash a solar push. These large eruptions of electromagnetic radiation can last minutes at hours and can disrupt certain radio transmissions on earth.

Very often, these lighting rockets are followed by a coronal mass ejection (CME), a large expulsion of sun particles which move faster than normal on the solar wind. When these particles reach the earth, they interact with our magnetic field and can create beautiful lights from the North, or Aurora Borealis.

In this case, two CMEs were unleashed on the sun on August 30 and went to earth.

According to Tamitha Skov, a space physicist and professor at the University of Millersville in Pennsylvania, none of the eruptions seemed to have a real meaning at the beginning. However, a more in -depth study shows that the second eruption was more powerful than initially planned.

“The second much larger storm has a hidden surprise,” said Skov in a YouTube video. “His signature during the eruption and later in coronagraphic imaging indicates that there can be a lot of coronal equipment on the path of us.”

Monday’s geomagnetic storm was a G2 on a storm scale from one to five. The SWPC provides a G3 geomagnetic storm for Tuesday evening.

Difficulty predicting the aurora

Now, the dawn are notoriously difficult to plan, so there is no guarantee that we will have a show this evening. However, several applications can tell you if they are visible in your region, including Aurora and Aurora alerts now.

Many people will probably remember the incredible displays of the Northern Lights on May 10, 2024 and 10 October 2024. These two storms have reached G5. The initial forecasts for the pair made them reach G3 or G4, an example of the difficulty of predicting precisely.

On these two occasions, the northern lights were visible in Canadian and American cities and went as southern as Mexico.

As for these storm forecasts, the first had an impact on earth on Monday, but the second is scheduled for Tuesday.

“We are planning a two of these two solar storms that are heading towards the earth,” said Skov. “At high latitudes, the Noaa expects serious storm conditions. It starts just around (September 2).”

This augurs well for Canadians, with a few cities with high latitudes. And for the many cities of what is considered to be mid-latitudes, the NOA also predicts a 50% chance of a strong geomagnetic storm in the coming 24 hours. For those who have high latitudes, it increases to 85%.

Several factors

Many things have to happen for those who have medium -sized latitudes to see the dawn, including how fast this solar wind moves and if the dawral oval – along which these particles interact with the molecules which produce the colors of the Enlightenment – the points to the south. Further south, the hole plunges, the deeper the south of the Aurora.

In order to determine the strength of a geomagnetic storm, Noaa uses the KP index, which varies from one to new. The higher the storm, the higher the number. For those in average latitudes, the number must generally be KP 6 or more, unless the conditions are ideal. You can check the SWPC website to see what is number.

During the writing, the KP was at four years old, with the dawn diving auroral in northern Europe.

Thus, the crossed fingers, the storm persists for the Canadians.

“Aurora’s photographers could get an excellent show if the magnetic field of this storm is favorably oriented, even in the mid-Latitudes,” said Skov.
