1/5 The Sun is the largest object in our solar system and is a 4.5 billion-year-old star – a hot glowing ball of hydrogen and helium at the center of the solar system. It is about 93 million miles (150 million kilometers) from Earth, and without its energy, life as we know it could not exist here on our home planet. (Pixabay)

2/5 The Sun’s volume would need 1.3 million Earths to fill it. Its gravity holds the solar system together, keeping everything from the biggest planets to the smallest bits of debris in orbit around it. The hottest part of the Sun is its core, where temperatures top 27 million degrees Fahrenheit (15 million degrees Celsius). The Sun’s activity, from its powerful eruptions to the steady stream of charged particles it sends out, influences the nature of space throughout the solar system. (NASA)

3/5 According to NASA, measuring a “day” on the Sun is complicated because of the way it rotates. It doesn't spin as a single, solid ball. This is because the Sun’s surface isn't solid like Earth's. Instead, the Sun is made of super-hot, electrically charged gas called plasma. This plasma rotates at different speeds on different parts of the Sun. At its equator, the Sun completes one rotation in 25 Earth days. At its poles, the Sun rotates once on its axis every 36 Earth days. (NASA)

Also, several spacecraft are currently investigating the Sun including Parker Solar Probe, STEREO, Solar Orbiter, SOHO, Solar Dynamics Observatory, Hinode, IRIS, and Wind. (Pixabay)

Find out all about the solar storm that is likely to hit the Earth tomorrow, July 20. (Pixabay)

Yesterday, it was reported that a long-duration solar flare eruption in the unstable sunspot region of AR3363 released a fast-moving coronal mass ejection (CME), that was found to be very intense. However, it was hard to determine whether it will hit the Earth or not. Today, the National Oceanic and Atmospheric Administration (NOAA) prediction models have confirmed that the CME will deliver a glancing blow to the Earth tomorrow, July 19. However, it cannot be stated just how devastating the resultant solar storm could be.

According to a SpaceWeather.com report, “NOAA models confirm that a CME will graze Earth's magnetic field on July 20th. It came from yesterday's potent M6-class eruption in the magnetic canopy of sunspot AR3363”. The report further added that there is a possibility that the geomagnetic storm can reach G3-class intensity. This could be one of the strongest storms of the year so far.

Solar storm expected to strike the Earth tomorrow

In April, the Earth was hit by a G3-class geomagnetic storm which not only delayed a SpaceX rocket launch but also forced oil rigs in Canada to stop operations due to an increase in static electricity in the environment. This is what can happen again tomorrow if a similar solar storm strikes. However, things can be even worse.

Storms like these can do more damage than usual. They can damage small satellites, impact mobile networks, and GPS, and even pose a threat to ground-based electronics and power grids by increasing the magnetic potential by huge amounts.

The aurora effect can also be seen much further south than normal. It is not unusual to see aurora displays as far south as Oregon and Nebraska in the US.

Right now, we can only wait till tomorrow to find out if the CME does make contact and the kind of intensity it brings along with it.

Know the GOES-16 satellite

GOES-16, formerly known as GOES-R before reaching geostationary orbit, is the first of the GOES-R series of Geostationary Operational Environmental Satellites operated by NASA and NOAA. It was launched on November 19, 2016, and became operational on December 18, 2017. GOES-16 is located in geostationary orbit over the Atlantic Ocean and provides continuous imagery and atmospheric measurements of Earth's Western Hemisphere. It also carries a lightning mapper, which can detect both cloud-to-cloud and cloud-to-ground lightning. GOES-16 is a vital tool for weather forecasting, climate monitoring, and space weather prediction.
