Solar flare hurls CME into space, sparking risk of geomagnetic storm

[ad_1] While Earth's magnetosphere deflects most solar activity carried by solar events, some charged particles seep through. These energetic particles cause magnetic disturbances, classified as Geomagnetic storms. These supercharged storms can wreak havoc on all forms of wireless communication, including GPS, mobile networks, and satellite communication. Power grids are also susceptible to fluctuations and could potentially sustain irreversible damage.In light of the danger that is posed by geomagnetic storms, forecasters at the National Oceanic and Atmospheric Administration (NOAA) have issued a warning against a potential CME impact that could hit Earth and spark a Geomagnetic storm soon.

Geomagnetic storms: Everything you wanted to know about this solar phenomenon in brief

[ad_1] Geomagnetic storms can wreak havoc on Earth as they have the power to destroy all the communications and electrical infrastructure on Earth and even the satellites up in the sky. And Earth has been, and is being, continuously bombarded by Geomagnetic storms, and not a single week has gone by without one incident of solar particles hitting our atmosphere recently. In fact, the year 2023 has been an eventful year for astronomers and skywatchers and you too should know what these storms are all about.So, do you know what geomagnetic storms are? Or how powerful they are? Here's all you need to know about these storms that have the potential to send us to the Dark Ages. What are Geomagnetic storms?Disturbances in the Earth's magnetic field that occur when the planet's magnetic field i...

Strong solar winds, CME approaching Earth; Could trigger G1-class Geomagnetic storm soon

[ad_1] Just yesterday, an unstable sunspot named AR3335 exploded, producing a solar flare that triggered blackouts over the Atlantic Ocean. The resulting solar flare was M2.5 in intensity and caused a shortwave radio blackout. Solar activity has been on the rise for the past few months, and it is expected to increase further until solar maximum, the period of greatest solar activity during the Sun's 11-year cycle. Solar flare riskAccording to a report by spaceweather.com, NASA's Solar Dynamics Observatory (SDO) forecasters have observed multiple streams of solar winds hurtling towards Earth from a coronal hole on the Sun's surface, and these could reach Earth tomorrow, June 21. Moreover, a CME is also expected to deliver a glancing blow on June 22. Both these events have the potential t...

CME hurled by the Sun to hit Earth soon! G1-class Geomagnetic storm on the cards

[ad_1] Solar activity has been at a high in the last few months and that is probably due to the approaching Solar Maximum. Sun entered solar cycle 25 in 2019 and it is expected that it will hit its peak in July 2025, thus resulting in increased solar activity even further during the peak. Therefore, we can expect solar phenomena such as sunspot eruptions, solar storms, solar flares, geomagnetic storms, and more, to bombard Earth.Recently, forecasters at the National Oceanic and Atmospheric Administration (NOAA) have issued a warning against a potential CME impact that could hit Earth and spark a Geomagnetic storm soon. According to a recent report by spaceweather.com, NOAA forecasters have been keeping an eye on a Coronal Mass Explosion (CME) that was hurled out by the Sun into space du...

Surprise G2-class Geomagnetic storm sparks stunning red auroras even in Missouri

[ad_1] 2023 has been an eventful year for astronomers and skywatchers. Not only have we witnessed several big asteroids pass by Earth at close distances, but other sky phenomena such as auroras have mesmerized us too. The planet has been continuously bombarded by solar storms since the turn of the year and not a single week has gone by without at least one incident being reported of solar particles hitting the atmosphere. Now, a geomagnetic storm surprised astronomers, and it sparked stunning red auroras which lit up the sky as far south as the US.Geomagnetic storm strikesOn May 19, a massive crack appeared in the Earth's magnetic field. Solar wind entered the planet's atmosphere through this gap and sparked a G2-class Geomagnetic storm, according to a report by spaceweather.com. Follow...

CME approaching Earth could spark G1-class Geomagnetic storm! Know details

[ad_1] We have seen rampant solar activity in the past few months. Natural phenomena such as sunspot eruptions, solar storms, solar flares, geomagnetic storms, and more, have been bombarding Earth. But why? According to NASA, this is because the Sun entered solar cycle 25 in 2019 and it is expected that it will hit its peak in July 2025, thus resulting in increased solar activity even further during the peak. Although this solar activity might seem harmless due to the distance of the Sun from our planet, it can cause major damage to infrastructure. Therefore, Earth is in for a rough ride until then.Recently, forecasters at the National Oceanic and Atmospheric Administration (NOAA) have issued a warning against a potential CME impact that could hit Earth soon.

Solar storm alert! Double solar flare erupts, triggers blackouts over North America

[ad_1] The Earth-facing side of the Sun has become a hotbed of intense solar activity. Due to the negative polarity of a sunspot complex, a large region has been continuously exploding since the last week. Many solar flares have erupted as a result, with an M1.5-class flare being the strongest so far. And today, an extremely rare double solar flare eruption has occurred, that has triggered blackouts over North America and the Pacific Ocean. It has also hurled a coronal mass ejection (CME) cloud, but it remains to be confirmed whether it was Earth-directed or not.According to a SpaceWeather.com report, “Reversed-polarity sunspot AR3296 just unleashed a double solar flare. Extreme ultraviolet radiation from the double blast ionized the top of Earth's atmosphere, causing a shortwave radio ...

Solar storm today! Shocking CME catches NOAA by surprise; Know the DANGER to Earth

[ad_1] The explosions on the Sun are not showing any signs of slowing down as we enter the third day of solar flare eruptions. Yesterday, multiple coronal mass ejection (CME) clouds were detected by NASA which were moving in different directions, although none were reported to be coming towards the Earth. But that did not last long. A few hours earlier today, the National Oceanic and Atmospheric Administration (NOAA) detected a large CME cloud sweeping past its DSCOVR satellite. This CME was not detected earlier and comes as a complete shock. Know how dangerous it is likely to be.According to a report by SpaceWeather, “An unexpected CME just swept across NOAA's DSCOVR spacecraft and it will soon hit Earth's magnetic field. The impact could spark G1 to G2-class geomagnetic storms with hi...

Earth to suffer DANGEROUS solar storm onslaught as Sun spits out solar flares

[ad_1] Yesterday, it was reported that a particularly notorious sunspot complex turned unstable and was frequently exploding, resulting in solar flare eruptions. The effect caused a rolling series of radio blackouts on Earth, which was particularly felt over the African continent. We are on day 2, and the explosions do not appear to be slowing down. In fact, one particular solar flare eruption has produced a large amount of coronal mass ejection (CME) cloud, which might hit the Earth. Astronomers have not been able to figure out the trajectory of the CME given the frequency of explosions but it should be clearer in hours to come.As per a SpaceWeather report, “Reversed-polarity sunspot AR3296 exploded on May 4th (0844 UT), producing an M3.9-class solar flare. The explosion also hurled a ...

Miracle! Huge Geomagnetic storm sparks Auroras in US, Europe, New Zealand, other regions

[ad_1] Rampant solar activity such as sunspot eruptions, solar storms, solar flares, geomagnetic storms and more, have all plagued Earth for the past few months. This is because the Sun entered solar cycle 25 in 2019 and it is expected that it will hit its peak in July 2025. Although this solar activity might seem harmless due to the distance of the Sun from our planet, it can cause major damage.Recently, forecasters at the National Oceanic and Atmospheric Administration (NOAA) revealed that a strong CME hit Earth on April 23 and caused a terrifying G4 class Geomagnetic storm. This further sparked stunning streaks of light in the sky, known as Auroras. What seems like a miracle and is quite shocking is that the Auroras lasted for a long time and were seen virtually all over the world! A...
