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...

Geomagnetic storm sparks breathtaking auroras; Know details of CME impact

[ad_1] The intensity of the Sun's activity has been rising in the last few months, and it is expected to increase even more as we approach the solar maximum. During this period, solar activity is at its peak, resulting in more solar flares, CMEs, solar storms and geomagnetic storms. All these solar phenomena hold the potential to cause damage on Earth. Technological instruments are especially at risk during these events, resulting in power blackouts and even disruption of radio communication.A few days ago, the Space Weather Prediction Center (SWPC) of the National Oceanic and Atmospheric Administration (NOAA) predicted that a CME was on course for Earth, and could hit the planet soon. Geomagnetic storm impactAccording to a report by spaceweather.com, the CME impact occurred on October ...

Geomagnetic storm could be triggered by CME today, says NOAA

[ad_1] Geomagnetic storm today: NASA's Parker Solar Probe on September 5 recorded one of the most powerful Coronal Mass Ejections (CMEs) ever as it flew by the Sun. According to NASA, the CME hurled out interplanetary dust to about 6 million miles, which is one-sixth of the distance between the Sun and Mercury. Astonishingly, the dust floating around in space replenished it almost immediately. Guillermo Stenborg, an astrophysicist at the Johns Hopkins Applied Physics Laboratory (APL) who led this study said, “These interactions between CMEs and dust were theorized two decades ago, but had not been observed until Parker Solar Probe viewed a CME act like a vacuum cleaner, clearing the dust out of its path.”In a separate development, forecasters at the National Oceanic and Atmospheric Admi...

How satellites are helping farmers adapt to global warming

[ad_1] When to harvest is one of the most crucial decisions a winemaker can make. Too early, and the result is bitter. Too late, and it's overly sweet. It's a delicate balance—one that's increasingly being upended by the climate crisis.In France, global warming has been wreaking havoc on this ancient equation for some time. Wine-growing regions across the country have seen seasons truncated—the harvest date in the Châteauneuf-de-Pape appellation, one of the most prized, has moved up almost three weeks since 1960. Simultaneously, plant diseases are appearing in regions that have never seen them before, rain patterns are changing and the heat that helped speed the harvest in some places is now drying out vines in others. To acclimate, the old ways are increasingly being replaced by the ne...

Earth will get under 20 min solar storm warning before it hits power grid

[ad_1] The world may have as little as 20 minutes to prepare for a solar storm that could severely impact power grids, it has been revealed. With solar activity expected to reach its peak in 2025, Earth's energy grids may not be adequately equipped to handle the consequences, The National News reported.The powerful bursts of energy emitted by the Sun during solar storms have the potential to cause physical damage and trigger magnetic storms that disrupt systems on the ground. Unfortunately, long-range forecasting in this field is currently inadequate, according to an official from the UK's Met Office, which is responsible for predicting space weather. While short-term forecasts are relatively accurate, predicting events over a longer timeframe proves challenging. Solar storms can also h...

Massive solar flare explodes from the Sun, reveals NASA’s Solar Dynamics Observatory

[ad_1] The Sun has just spewed out a massive solar flare. While this one is big, the fact is that solar flares are increasing in number and strength and this is worrying astronomers. And this is despite the fact that we have not reached the peak of solar flare season yet. The current activity on the Sun is definitely exceeding scientific predictions, NASA reveals. Since December 2019, solar cycle 25 has marked a number of solar events that showed how far our Sun was exceeding expectation. According to NASA, these solar flares will continue to increase and can create a serious impact on Earth, technology, satellites, and astronauts in space.NASA believes that the Sun is near its peak, which means it is at nearly its most active. This phenomenon of the active sun is called the solar maxim...

Rains ahoy! Track the Monsoon with these 3 weather apps – MAUSAM, Skymet, AccuWeather

[ad_1] India's southwest monsoon, which had experienced a two-week delay, is expected to gain momentum over the upcoming weekend, providing much-needed rainfall to the central, western, and northern regions, as stated by the India Meteorological Department (IMD). The delay has resulted in a significant 33% shortfall in June's rainfall nationwide, with certain areas experiencing a staggering 94% deficit. Traditionally, by June 25, the monsoon's western branch would have made substantial progress into Gujarat. However, this year, Cyclone Biparjoy hindered its advancement by absorbing all available moisture from the Konkan coast.June plays a crucial role in the monsoon season, contributing around 16-17% of the overall rainfall, particularly important for the agricultural sector.

Solar storm to strike Earth at 3.6 million mph, may spark geomagnetic storm

[ad_1] A powerful burst of plasma, called a coronal mass ejection (CME), is set to hit Earth at any time. It is travelling at an incredible speed of 3.6 million kilometres per hour through the inner planets. The solar storm will have many consequences for Earth.When the CME collides with Earth's magnetic field, it is likely to cause a G3-class geomagnetic storm. This could lead to vibrant auroras in the sky. The impact of a CME on Earth depends on several factors, such as its speed, direction, and magnetic fields. If the CME is directed towards Earth and its magnetic fields align with Earth's, the impact can be more severe. The plasma blast erupted from the Sun on May 9, and a large part of it is aimed at Earth.Geomagnetic storms occur when the CME's magnetic fields interact with Earth'...

Confusion as Elon Musk’s Twitter yanks blue ticks from agencies

[ad_1] Twitter has long been a way for people to keep track of tornado watches, train delays, news alerts or the latest crime warnings from their local police department.But when the Elon Musk-owned platform started stripping blue verification checkmarks this week from accounts that don't pay a monthly fee, it left public agencies and other organizations around the world scrambling to figure out a way to show they're trustworthy and avoid impersonators. High-profile users who lost their blue checks Thursday included Beyonce, Pope Francis, Oprah Winfrey and former President Donald Trump. But checks were also removed from accounts for major transit systems from San Francisco to Paris, national parks like Yosemite, official weather trackers and some elected officials. Twitter had about 300...
