Solar storm alert: X-class solar flares may be hurled towards Earth by sunspot AR3615

[ad_1] On Sunday, a severe geomagnetic storm struck Earth. This happened just days after the Sun unleashed an X-class solar flare and hurled out a stream of boiling hot plasma, known as a Coronal Mass Ejection (CME) towards the planet. This development comes at a time when the solar maximum is approaching, which will likely lead to increasing frequency and intensity of solar phenomena such as solar storms, CMEs, solar flares, geomagnetic storms and more. The latest instance of this devastating solar activity may show up today or tomorrow in the form of an X-class solar flare, raising a potential solar storm threat.

Severe G4 Geomagnetic storm hits Earth! Solar storm could spark radio blackouts, auroral displays

[ad_1] In a recent alert from the National Oceanic and Atmospheric Administration (NOAA), Earth experienced a severe G4 geomagnetic storm on Sunday, indicating potential disruptions to radio communications. The NOAA emphasised that while the storm may fluctuate in intensity, ranging from lower levels to severe conditions, there's no need for panic among the public. However, staying informed about the storm's progression via NOAA's webpage is encouraged. The NOAA's alert notifies infrastructure operators to take mitigating actions against possible impacts, including increased voltage control problems and potential effects on satellite operations. The severity of the storm, hitting the G4 level on the NOAA's 5-point scale, arrived earlier than anticipated, reaching its threshold at 16:28 ...

Sun hurls out strongest solar flare since 2017, two other X-class flares! Know the solar storm danger

[ad_1] The current solar cycle is expected to peak this year, according to scientists. Consequently, we've seen an increase in the number as well as the intensity of solar phenomena such as solar flares, solar storms, CMEs and more. In a new incident, the Sun has hurled out as many as three solar flares towards Earth, and one of them is the strongest solar flare of the solar cycle 25! This poses a potential solar storm danger. Know details.Solar storm dangerAccording to NASA, the Sun spewed out two solar flares just 7 hours apart yesterday, February 22. The first flare had an intensity of X-1.8, while the second one was recorded as an X-1.7 solar flare. However, just a few hours later, the worst solar flare of the three was hurled out. This solar flare was measured at X-6.3 in intensit...

Strong M-class solar flare sparks radio blackout over Australia, Southeast Asia

[ad_1] Sunspot AR3575 has been spewing out large amounts of solar material lately, with multiple coronal mass ejections and solar flares originating from this source. On February 6, this sunspot hurled out a dangerous M-class solar flare that caused blackouts in several regions around the world. Solar activity has been on a dangerous rise in the last few months, and it is expected to increase as we approach solar maximum. Know all about the strong M-class solar flare that impacted Earth in the last few days.M-class solar flareIn an X post, Space Weather Physicist Dr. Tamitha Skov wrote, “As if on cue, Region 3575 fires an M4.2-flare with a high R1-level #RadioBlackout and launches a gorgeous #solarstorm.

Solar storm danger: Sunspot ‘10 times wider than Earth’ could hurl out M-class solar flares

[ad_1] Earth witnessed f X-class solar flares a number of times in the last few months. For the unaware, X-class solar flares are the most intense flares which can result in long-lasting radiation storms. In December, there were two instances of terrifying X-class solar flares hitting the planet, one of which caused a radio blackout in the polar regions for almost 3 days. Now, another solar storm danger has been highlighted as a massive sunspot on the solar surface could hurl out M-class solar flares towards Earth. Know all about this solar storm danger. Solar storm dangerAccording to the National Oceanic Atmospheric Administration (NOAA), sunspot AR3559 tripled in size over the weekend, and it is now 10 times wider than Earth! It has more than 12 dark cores. NASA says you need just ecl...

Solar storm alert! NASA says 3 sunspots could hurl out M-class solar flares

[ad_1] Solar storm alert: Sunspots, solar storms, solar flares, and geomagnetic storms…that was the story of space weather in 2023, and 2024 has kicked off in the same manner. On the last day of 2023, we saw the strongest solar flare emitted since 2017, and it sparked radio blackouts for nearly 4 days in the polar regions. Just a few days later, 4 sunspots with unstable beta-gamma' magnetic fields hurled out M-class solar flares. This is just an indication of the Sun's might and as we approach the solar maximum that will likely occur in 2024-25, its wrath is only expected to increase. NASA has now revealed that 3 sunspots could hurl out M-class solar flares, resulting in a solar storm. Check out the details of this solar storm alert below.Solar storm alertAccording to the National Ocean...

Solar storm warning: Unstable sunspots could hurl out X-class solar flares today, NASA says

[ad_1] Even though we're just 4 days into 2024, we've seen already seen several strong solar flares hurled out towards Earth, sparking a solar storm. On December 31, the Sun hurled out an X-class solar flare that hit Earth just a few days ago, and it is still causing radio blackouts in the polar regions. The Sun has been showing all its might for the past couple of months and as we approach the solar maximum that will likely occur in 2024-25, its wrath is only expected to increase. NASA has revealed that the effects of this rising solar activity are now being seen again as multiple sunspots possess energy for solar flares that can spark a solar storm.

NASA says two sunspots could hurl out M-class solar flares towards Earth; Check details

[ad_1] Earth has been bombarded with solar activity in the last few months. In July, it was revealed that 2023 had already broken a 21-year record for the highest number of sunspots which were even more than initially predicted by scientists. But what does the rising number of sunspots mean? The number of sunspots on the Sun is directly related to the intensity of the solar peak. So, the higher the number of sunspots, the higher the chances of solar storms. Solar storms are caused by coronal mass ejections (CME) particles released whenever a solar eruption occurs. These eruptions, also known as solar flares, occur at the center of sunspots, which are the regions of unstable magnetic fields on the surface of the Sun. In a new development, the NASA Solar Dynamics Observatory (SDO) has tra...

Aditya- L1 mission: Not just India, Japan and China too have their solar missions

[ad_1] In a significant stride towards unravelling the mysteries of our star, India recently marked its entry into solar exploration with the launch of Aditya-L1 mission on September 2. This spacecraft, having executed a Trajectory Correction Maneuver on October 6, is now en route to the Lagrange point L-1, situated 1.5 million kilometres away from the Earth and facing the Sun. Aditya-L1 mission aims to delve into the real-time effects of the Sun on space weather. India is not alone in venturing into the realm of solar missions; other countries have embarked on similar endeavours like Japan, China, Japan and more. JapanBack in 1981, Japan initiated its solar exploration journey with the launch of the Hinotori (ASTRO-A) satellite, focusing on studying solar flares. Since then, Japan's sp...

NASA says strong incoming solar winds could spark geomagnetic storm on Earth

[ad_1] The barrage of solar activity continues as we near the peak of solar cycle 25. For the unaware, a solar cycle is an 11-year period where the Sun's activity dips and rises. The lowest point of activity in the cycle is known as the solar minimum, while the period of highest activity is known as the solar maximum. As we approach the solar maximum, Earth is predicted to face more CMEs, sunspots, solar flares, and solar storms. NASA's Solar Dynamics Observatory (SDO), which carries a full suite of instruments to observe the Sun, has now revealed that a strong stream of solar wind is flowing towards Earth and it could spark a geomagnetic storm. Know all about this latest development. Geomagnetic stormYesterday, it was revealed that a sunspot on the solar surface containing almost 12 d...
