- Geomagnetic storms on Earth can affect power grids, GPS navigation systems, and radio and satellite telecommunications.
- The storm is rated “G3,” which is the third level on the NOAA five-level geomagnetic storm scale.
- Geomagnetic storms can produce spectacular auroras here on Earth.
A spectacular aurora, also known as the Northern Lights, could be visible in some northern states this weekend as a “strong” geomagnetic storm is forecast for Earth.
The storm is caused by a large solar flare and coronal mass ejection from the sun that occurred around 11:35 a.m. EDT on Thursday, October 28, scientists from NOAA’s Space Weather Prediction Center said on Friday.
The Space Weather Prediction Center has informed power grid operators, satellite operators, airlines and other customers of the potential impacts of a geomagnetic storm. “Geomagnetic storms on Earth can affect power grids, GPS navigation systems, and radio and satellite telecommunications,” the Center said.
The solar flare was the second strongest flare from the sun this year, according to Space.com.
The storm is rated “G3,” which is the third level on the NOAA five-level geomagnetic storm scale. (G1 storms are minor, while G5 storms are considered extreme.) G3 storm monitoring is in effect here on Earth on Saturday and Sunday.
Geomagnetic storms can produce spectacular auroras on Earth. The aurora forecast for this geomagnetic storm includes the potential for dawn as far south as Pennsylvania, Iowa and Oregon by Saturday night.
“This could be a big show for people in the mid to upper latitudes of the United States for the Aurora,” NASA’s C. Alex Young told Space.com.
What is a solar flare? :And how can a geomagnetic storm make the aurora visible in the United States?
These storms can heat the ionosphere – where Earth’s atmosphere meets space – causing the beautiful auroras here on Earth.
As a result, the Northern Lights can be visible to astronomers in some places in the United States and in the far north of the world. The aurora australis, known as the aurora australis, can also be seen in the far south of the world.
The impacts of this geomagnetic storm are expected to ease by early next week.
