Massive M5-class solar flare erupts on Sun; blackouts hit Earth, solar storm coming too, shows NASA

[ad_1] Yesterday, it was the turn of Mars, and today, December 9, the Earth is again the central focus of the unceasing solar activity on the Sun. Just four hours ago, a massive solar flare eruption took place on the Sunspot AR3511, according to data from NASA. The solar flare was measured to be M5.49, which is the highest-intensity flare we have seen in the last three months. The flare subsequently triggered a short-wave radio blackout on Earth. It is possible that the flare also released a coronal mass ejection (CME) cloud directed toward the Earth. If it did, the Earth could suffer an intense solar storm event in the next 2-3 days.According to a report by SpaceWeather.com, “Sunspot AR3511 erupted on Dec. 8th (2307 UT), producing an M5-class solar flare and a shortwave radio blackout ...

Two CMEs hit Earth, spark extra strong solar storm; NASA model shows more could be on the way

[ad_1] The solar activity on Earth has intensified. Yesterday, December 1, it was reported that a second coronal mass ejection (CME) was headed for the Earth which could turn the ongoing solar storm even more intense, and exactly that happened. A few hours earlier, the second CME made an impact and sparked an incredibly powerful G3-class solar storm. The storm resulted in some of the brightest aurora displays seen across the world. While it has begun subsiding slowly, a NASA model has shown that more CMEs are headed toward the Earth and might make contact with our magnetosphere before the end of the day.According to a report by Spaceweather.com, “One and possibly two CMEs hit Earth's magnetic field on Dec. 1st, sparking a strong G3-class geomagnetic storm. At the apex of the event, just...

Earth to suffer direct CME hit, new NASA model reveals; To spark solar storm and auroras

[ad_1] Yesterday, the NASA Solar and Heliospheric Observatory (SOHO) detected a coronal mass ejection (CME) that appeared to be coming towards the Earth. The early assessment revealed that it could hit the Earth in the late hours of November 11, although it wasn't clear whether the strike would be a direct one or a glancing blow. Earlier today, NASA ran the data through its prediction model and we have a much clearer picture of what is to come. The CME is now expected to hit the Earth tomorrow, November 12. It is also expected to be a head-on collision, and the solar storm can reach an intensity of G2-class.Tamitha Skov, space weather physicist, and solar storm enthusiast, posted on her X account about the NASA model and said, “A #Solarstorm Encore: A new direct hit comes!

NASA SOHO spots CME headed for Earth tomorrow; Solar storm may spark auroras, radio blackouts

[ad_1] Even with just six Earth-facing active sunspots on the Sun, the solar activity in the last fortnight has been more intense than many months combined this year. This is the second most intense solar storm spell we have seen since March when two G3-class storms were spotted in the same month. To make matters worse, it is not likely to stop anytime soon. The NASA Solar and Heliospheric Observatory (SOHO) has detected a halo-shaped coronal mass ejection (CME) headed towards the Earth. The data highlights that it will make strike the Earth tomorrow, November 11, in the late hours, triggering a solar storm that can be as intense as G2-class.According to a report by SpaceWeather.com, “Coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) detected a halo CME leaving the sun....

MASSIVE solar storm to strike Earth, Venus and Mars, reveals NASA; Know the DANGER

[ad_1] On June 20, an X1.1-class solar flare erupted on the Sun, making it one of the biggest explosions seen this year. The flare sparked a shortwave radio blackout across North America that affected wireless communications for as long as 30 minutes after the flare first erupted. NASA also spotted a massive coronal mass ejection (CME) cloud escaping after the blast. This CME is extremely potent and has been classified as Type II solar emission. This dangerous CME is capable of delivering an extremely dangerous solar storm. Luckily, its main targets are Venus and Mars, but even the Earth can get hit by a glancing blow from it.According to a SpaceWeather.com report, “A CME launched into space will hit Venus and Mars, according to a NASA model. The strike on Venus (June 22nd) will probabl...

Powerful M-class solar flare sparks blackout over Atlantic Ocean! NOAA shares details

[ad_1] Over the recent weeks, the Sun has emitted massive amounts of energy in the form of solar flares. While some of these flares unleashed from the Sun pass harmlessly into space, others hit Earth, resulting in geomagnetic storms. Over the past few days, an unstable sunspot named AR3335 has caused concerns due to the possibility of it releasing hazardous solar flares. For those unfamiliar, a sunspot is a dark area on the Sun's surface that appears due to intense magnetic activity.As per a SpaceWeather.com report, this unstable Sunspot AR3335 exploded on June 18th. Resultantly, it produced an M2.5-class solar flare. “The explosion lasted long enough to lift a CME out of the sun's atmosphere since confirmed by SOHO coronagraphs,” the report added. How strong it is? According to NASA, s...

Solar storm DANGER looming! NASA’s SOHO shows high number of sunspots will face Earth soon

[ad_1] The second half of May and the first week of June were relatively quiet in terms of solar activity. The Earth did suffer a radio blackout earlier this week when sunspot AR3327 exploded and produced an M4.6-class solar flare. The sunspot has not exploded since then and it is likely that like the other sunspots present on the Earth-facing side of the Sun, it will also dissipate. However, the next week might bring trouble for our planet as the NASA Solar and Heliospheric Observatory (SOHO) has spotted a high number of active sunspots on the farside of the Sun. Researchers believe that it can bring a spell of strong solar storms to Earth.As per a report by SpaceWeather.com, “Helioseismic maps of the farside of the sun show multiple large active regions, probably sunspots. This means ...

Dangerous sunspot boosts solar flare risk to new high today! Blackouts expected

[ad_1] A dangerous sunspot has emerged on the Sun and it may have a significant effect on Earth! Just a few days ago, there was no sign of sunspot AR3315. However, according to SpaceWeather.com, it has now become the largest and most dangerous sunspot on the visible part of the Sun- the side facing the Earth at the moment. This sunspot, designated as AR3315, possesses a magnetic field classified as 'beta-gamma-delta,' which contains a considerable amount of energy capable of triggering powerful eruptions. For those who may not know, a sunspot is a dark, relatively cooler region that appears on the surface of the Sun due to intense magnetic activity. The experts at NOAA predict a 55 percent probability of an M-class solar flare. However, things may get really serious too. It also says th...

Sunspot changes Sun’s vibration! Solar storm THREAT faces Earth, shows NASA’s SOHO satellite

[ad_1] After days of warnings for a G3-class geomagnetic storm, yesterday the coronal mass ejection (CME) finally hit the Earth and it turned out to be a dud. The impact only sparked minor G1-class storms briefly before being dispersed by the planet's magnetosphere. While the Earth was lucky in this encounter, soon a far bigger problem is coming its way. Researchers have spotted a huge sunspot group on the farside of the Sun and it is big enough to change the way the Sun vibrates. It is expected to face our planet the next week and is expected to be active. Concerns are that if it blasts a CME cloud towards us, we might suffer a severe solar storm event.As per a report by SpaceWeather.com, a massive sunspot group was revealed by Standford researchers. “The black blob is a sunspot group-...

Solar storm strikes Earth! Blackouts affect parts of USA as MASSIVE solar flare erupts

[ad_1] Last week, astronomers witnessed really high solar activity after a sunspot complex turned unstable and began exploding. Over a period of four days, the sunspot triggered solar flares at regular intervals creating a rolling series of blackouts over the Earth. But the worst of it came on Sunday, May 7, when an M1.5-class solar flare erupted and the ultraviolet radiation caused a shortwave radio blackout over the western USA and part of the Pacific Ocean. Concerns are now rising on whether a solar storm has been triggered by the solar flare or not.According to a report by SpaceWeather.com, “Reversed-polarity sunspot AR3296 just did it again. The backwards active region exploded on May 7th (2234 UT), producing a long-lasting M1.5-class solar flare. The blast was squarely Earth-direc...
