Lasting from Wednesday through Thursday, the geomagnetic storm will also impact the Earth’s magnetosphere — or magnetic field, which is impacted by changing solar winds. That means the storm could cause minor “power grid fluctuations” and have small impacts on orbiting satellites, according to the Space Weather Prediction Center from the National Oceanic and Atmospheric Administration.
It appears this upcoming event will allow residents in U.S. to catch a rare glimpse of the northern lights. The center says residents in the northern tier of the U.S., including Michigan and Maine, may be able to see the auroras.
A G1 Watch is in effect for the 14 & 15 March, 2018 UTC-days. Enhancements in the solar wind due to the anticipated effects of a coronal hole high speed stream (CH HSS) are expected to cause the escalated geomagnetic responses.

According to a graph from the space center, it also appears states like North Dakota, South Dakota, Minnesota and Wisconsin could also see the lights as a result of the storm. In addition, the northern-most part of Ireland, Norway, and parts of Sweden and Finland can see the lights.
The minor storm is classified as G1, which is the lowest on the scale of intensity from the Space Weather Prediction Center. These kinds of storms occur about 2,000 times over 11 years, the center says, which amounts to more than 180 times per year. The highest level of this kind of storm is a G5, which would involve a “high frequency radio blackout” on the sunlit side of the world for several hours, according to the center. Those come once every 11 years. The largest of these storms come as a result of the release of plasma from the Sun’s corona, called coronal mass ejections, that arrive at Earth and disturb its magnetic fields.
