NASA spotted a solar flare releasing a coronal mass ejection earlier this week

National Oceanic and Atmospheric Administration issued a 'G1' storm watch

G1 is used to label a 'minor' storm that can cause weak power grid fluctuations, impact satellites and spark auroras

A massive solar storm is making its way towards Earth, and it's likely to hit today.

The storm was created by a solar flare - a large explosion in the sun's atmosphere - which generated charged particles earlier this week.

The charged particles from the sun are moving towards Earth, and they could disrupt power grids, spacecraft and satellite operations.

The solar particles are expected to hit Earth either today or tomorrow, and they will also likely trigger auroras for people living in higher latitudes.

A solar storm is forecast to hit Earth today after the sun unleashed a powerful solar flare on Sunday night. Nasa's Solar Dynamics Observatory Satellite captured this image of the sun releasing a solar flare (right) earlier this week

'Aurora may be visible at high latitudes,' the National Oceanic and Atmospheric Administration wrote in a statment.

This may include the 'northern tier' of the US, with affected states including parts of Michigan and Maine.

The NOAA says that the forecast suggests the solar storm will be a G-1 or 'minor' storm, which could become a G-2 'moderate storm' depending on how the charged particles hit Earth.

Geomagnetic storms are ranked on a severity scale, with G at the bottom, R in the middle and S at the top.

The particles, which came from the sun after a solar flare took place on February 12, could cause 'weak power grid fluctuations' and a 'minor impact on satellite operations,' according to the NOAA.

NASA and the NOAA keep a track of solar events using many different telescopes which help generate geomagnetic weather forecasts.

Researchers also study the sun to learn more about its structure as well as obtain data to make predictions about different types of solar events, such as solar flares and Coronal Mass Ejections, which are large clouds of plasma and magnetic field that erupt from the sun.

Solar flares and particles ejected via coronal mass jections are associated with dark spots on the sun's surface.

These are areas of intense magnetic activity, and when the magnetic fields in a sunspot cross each other, it can result in an energy explosion, known as a solar flare, which sends radiation into space.

SOLAR STORMS PRESENT A CLEAR DANGER TO ASTRONAUTS AND CAN DAMAGE SATELLITES Solar storms, or solar activity, can be divided into four main components that can have impacts on Earth: Solar flares : A large explosion in the sun's atmosphere. These flares are made of photons that travel out directly from the flare site. Solar flares impact Earth only when they occur on the side of the sun facing Earth.

Solar flares impact Earth only when they occur on the side of the sun facing Earth. Coronal Mass Ejections (CME's) : Large clouds of plasma and magnetic field that erupt from the sun. These clouds can erupt in any direction, and then continue on in that direction, plowing through solar wind. These clouds only cause impacts to Earth when they're aimed at Earth.

These clouds only cause impacts to Earth when they're aimed at Earth. High-speed solar wind streams : These come from coronal holes on the sun, which form anywhere on the sun and usually only when they are closer to the solar equator do the winds impact Earth.

: These come from coronal holes on the sun, which form anywhere on the sun and usually only when they are closer to the solar equator do the winds impact Earth. Solar energetic particles : High-energy charged particles thought to be released primarily by shocks formed at the front of coronal mass ejections and solar flares. When a CME cloud plows through solar wind, solar energetic particles can be produced and because they are charged, they follow the magnetic field lines between the Sun and Earth. Only charged particles that follow magnetic field lines that intersect Earth will have an impact. While these may seem dangerous, astronauts are not in immediate danger of these phenomena because of the relatively low orbit of manned missions. However, they do have to be concerned about cumulative exposure during space walks. This photo shows the sun's coronal holes in an x-ray image. The outer solar atmosphere, the corona, is structured by strong magnetic fields, which when closed can cause the atmosphere to suddenly and violently release bubbles of gas and magnetic fields called coronal mass ejections The damage caused by solar storms Solar flares can damage satellites and have an enormous financial cost. The charged particles can also threaten airlines by disturbing Earth's magnetic field. Very large flares can even create currents within electricity grids and knock out energy supplies. When Coronal Mass Ejections strike Earth they cause geomagnetic storms and enhanced aurora. They can disrupt radio waves, GPS coordinates and overload electrical systems. A large influx of energy could flow into high voltage power grids and permanently damage transformers. This could shut off businesses and homes around the world.

Some regions may experience some weak power grid fluctuations, though astronomers say that this is unlikely to happen in a minor G1 storm such as this

Solar flares only impact Earth when they occur on the side of the sun facing the Earth.

Sometimes, these explosions can send out coronal mass ejections - large clouds of plasma and magnetic field that erupt from the sun.

These clouds can erupt in any direction, and then continue on in that direction, plowing through solar wind, but they only cause impacts to Earth when they're aimed at Earth.

The National Oceanic and Atmospheric Administration (NOA) issued a G1 (minor) geomagnetic storm watch for tonight. Shown here is the forecast for auroras tonight, which are expected to hit areas of North America

Forecasters monitor these events, and when a storm looks likely to have a significant impact, engineers can shut down certain systems on satellites, or prepare for impacts on the power grid.

The sun has an 11-year cycle of sunspot activity, with the last maximum having taken place in April 2014.

This summer, NASA is set to launch a spacecraft called Parker Solar Probe, which will travel closer to the sun than any other previous mission.

It will fly by Venus and travel into the corona - the sun's upper atmosphere, with the aim of learning more about the particles that are ejected by the sun.
