Solar Storm Fury! Geomagnetic storm likely to be sparked tomorrow, NOAA warns

The effect of a double whammy solar storm unleashed by the Sun will likely be seen on Earth tomorrow, NOAA forecasters have suggested.

Geomagnetic storm
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)

4/5 Above the Sun’s surface are its thin chromosphere and the huge corona (crown). This is where we see features such as solar prominences, flares, and coronal mass ejections. The latter two are giant explosions of energy and particles that can reach Earth. (Pixabay)

5/5 The Sun doesn’t have moons, but eight planets orbit it, at least five dwarf planets, tens of thousands of asteroids, and perhaps three trillion comets and icy bodies. Also, several spacecraft are currently investigating the Sun including Parker Solar Probe, STEREO, Solar Orbiter, SOHO, Solar Dynamics Observatory, Hinode, IRIS, and Wind. (Pixabay)

As many as two solar storms are set to impact Earth! These were generated by a couple of partially Earth-directed coronal mass ejections (CMEs), spewed out by the Sun on July 4 and they are currently on their way. This solar activity, when it hits the Earth's atmosphere will likely generate geomagnetic storms on Earth. The likely date, when the first solar storm hits Earth and triggers a geomagnetic storm, is July 7. This has been confirmed by the National Oceanic and Atmospheric Administration's (NOAA) forecasters.

NOAA has warned that a G1-class geomagnetic storm is likely to hit Earth on 7 July. "Magnetic responses are likely to reach the G1 (Minor) geomagnetic storm levels, with a chance for G2 storm levels if more favourable conditions are observed. Stay tuned to our webpage for up-to-date information and forecasts," the NOAA report mentioned.

Apart from the report by NOAA, Space Weather specialist, Dr. Tamitha Skov took to Twitter and said, "The Sun launches double punch #solarstorms on #July4th! NASA prediction shows impact before noon July 7 UTC. The first storm is slower & will go mainly northeast. The second is faster & more of a direct hit. The fast solar wind follows. G1-level possible with #aurora to mid-latitudes (sic)."

The geomagnetic storm is also expected to generate auroras too and that should be a fascinating sight for those who like to gaze at the skies.

Radio Blackouts and more!

NOAA experts have further revealed that Radio blackouts have reached the R1 levels in the past 24 hours. The largest Radio Blackout was observed on Jul 06 2023 10:49 UTC (4:19 PM IST). Meanwhile, solar activity is expected to continue at lower levels through the 8th of July with a slight chance for M-class flares.

All of these solar activities are being tracked by NOAA's DSCOVR satellite to monitor solar storms and the Sun's behaviour. While the Space Weather Prediction Center further analyses this data to measure certain factors such as temperature, speed, density, degree of orientation, and frequency of solar particles.
