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 ...

Anticipating Solar Fireworks: What to Expect During the April 8 Total Solar Eclipse

[ad_1] As the April 8 total solar eclipse draws near, sky gazers prepare for an astronomical display that promises not only a captivating display of darkness but also the potential for witnessing rare solar phenomena. For those fortunate enough to be in the path of totality, a brief period of darkness, known as totality, will offer a unique opportunity to observe the sun's corona without the need for solar eclipse glasses.During totality, observers may catch a glimpse of dark-pink towers and loops of electrically charged plasma stretching into space, known as prominences. These awe-inspiring structures were vividly observed during the last total solar eclipse in Australia in 2023 and are expected to make a stunning appearance once again, given the sun's heightened activity during its 11...

How this most intense geomagnetic storm that brought auroras to Ladakh was tracked by Indian astronomers

[ad_1] In late-April 2023, Earth experienced a powerful geomagnetic storm that illuminated the skies with mesmerizing auroras, even in lower latitudes like Ladakh in India. Mostly, these auroras are restricted to the North Pole and northern regions of the world, but this geomagnetic storm was so powerful that it generated auroras that could be seen as far South as in Ladakh. Now, Indian astronomers have traced the origins of this intense storm back to the Sun. Notably, they used data collected from multiple space telescopes operating across different wavelengths. Coronal mass ejections (CMEs), massive eruptions of ionized gas and magnetic fields from the Sun, are known to trigger geomagnetic storms when they interact with Earth's magnetic field. These storms can have significant impacts...

ISRO’s Aditya-L1 mission reaches a milestone as PAPA detects coronal mass ejections

[ad_1] India's maiden solar mission, Aditya-L1, has achieved a significant milestone as the advanced sensors aboard the spacecraft successfully detected the coronal mass ejections (CMEs). Developed by the Indian Space Research Organisation (ISRO), the payload— Plasma Analyser Package for Aditya (PAPA)— played a pivotal role in capturing these crucial observations.PAPA is an energy and mass analyser designed for in-situ measurements of solar wind electrons and ions in the low energy range. Equipped with two sensors— the Solar Wind Electron Energy Probe (SWEEP) and the Solar Wind Ion Composition Analyser (SWICAR)— PAPA can measure electrons and ions in specific energy ranges and even determine the direction of arrival of solar wind particles. According to ISRO statements, the data collec...

Aditya-L1 mission: ISRO fixes course of spacecraft rocketing towards the Sun

[ad_1] India's first solar space observatory, Aditya-L1, is now on its way to the Sun-Earth Lagrange Point-1 (L1), which is about 1.5 million kilometers away from Earth. Aditya-L1 mission has gone off perfectly and it is expected to make yet another amazing achievement for India and ISRO scientists. But before reaching its destination, ISRO had to make a small adjustment in the path of the Aditya-L1 mission spacecraft.Recently, Aditya-L1 mission spacecraft performed a Trajectory Correction Maneuver (TCM) on October 6. This maneuver was necessary to make sure Aditya-L1 stay on the right course after a previous operation called Trans-Lagrangian Point-1 Insertion (TL1I), which happened on September 19, 2023.

Aditya-L1 mission: Massive data coming, here is how ISRO is preparing for it

[ad_1] The Aditya L-1 mission spacecraft is well on its way to the L-1 point from where it will constantly watch the Sun. ISRO expects it to generate massive amounts of data and for that, it will require huge manpower. The Indian Institute of Technology Kanpur (IITK) recently hosted the fifth Aditya-L1 Mission workshop in collaboration with the Aryabhatta Observational Science Research Institute (ARIES), Nainital. This three-day workshop was organised by the Department of Physics at IIT Kanpur and the Aditya-L1 Support Cell. These efforts are expected to yield great results derived from the information provided by Aditya L-1.Bridging Theory and PracticeThe Aditya-L1 Mission, undertaken by ISRO, marks India's inaugural journey to study the Sun, its atmosphere, and its influence on Earth....

Solar flare eruptions likely soon, but solar storms not seen hitting Earth over the weekend

[ad_1] This weekend promises a stark contrast to the geomagnetic fireworks we witnessed last week. Unlike the previous weekend, there are no looming Coronal Mass Ejections (CMEs) threatening Earth's magnetic field. Our planet's magnetosphere is expected to remain serene and undisturbed from any solar storm.According to a report by spaceweather.com, forecasters at the National Oceanic and Atmospheric Administration (NOAA) have revealed details of the sunspot AR3451, a newcomer on the solar stage, which has suddenly sprung to life. It has rapidly grown over the past 24 hours, boasting more than a dozen dark cores, two of which are larger than Earth itself. While magnetic observations of this sunspot are not conclusive due to its orientation away from Earth, it seems to possess a complex '...

ISRO’s solar mission Aditya-L1 to be launched on September 2, says space agency

[ad_1] After the successful Chandrayaan-3 mission to the Moon, ISRO on Monday announced that India's first solar mission Aditya-L1 to study the Sun will be launched on September 2 at 11.50 am from Sriharikota spaceport.Aditya-L1 spacecraft is designed to provide remote observations of the solar corona and in-situ observations of the solar wind at L1 (Sun-Earth Lagrange point), which is about 1.5 million kilometres from the Earth. Lagrange Points are positions in space where the gravitational forces of the Sun and the Earth produce enhanced regions of attraction and repulsion. These can be used by spacecraft to reduce fuel consumption needed to remain in position, according to NASA. Lagrange points are named in honor of Italian-French mathematician Josephy-Louis Lagrange.

Solar storm warning: NASA’s Mars rover snaps Sun turning, spies dangerous sunspot facing Earth

[ad_1] In an intriguing celestial observation, NASA's Perseverance Rover on Mars has captured a striking view of a massive sunspot, signalling a region of heightened solar solar activity on the far side of the Sun. This sunspot is rotating to face the Earth and the likelihood of a solar storm has just increased manifold.Early Solar WarningAccording to a blog post on spaceweather.com, the unique positioning of Mars on the opposite side of the sun allows Perseverance to provide advanced notice of approaching sunspots, sometimes more than a week before they become visible from our planet. This early alert has been issued: A significant sunspot has been seen and a solar storm could be enroute.
