NOAA WARNS OF A POSSIBLE GEOMAGNETIC STORM AS A RESULT OF TODAY'S POWERFUL SOLAR EXPLOSION.

By -


A strong solar outburst has shot a solar magnetic storm toward Earth, which is expected to smash the planet on Wednesday. The explosion occurred at the enormous sunspot region AR2936, which had grown in size in recent weeks, causing a Coronal Mass Ejection (CME) to be directed at Earth.

According to the Center of Excellence in Space Sciences at the Indian Institute of Science Education and Research in Kolkata, the CME from the Sun is expected to arrive between February 2 late evening and February 3 morning. "However, the impact speed is expected to be slow. We can anticipate minor to moderate changes "According to the institution.

An M1-class solar flare launched the CME into space on January 30. The flare lasted nearly four hours, propelling debris into space and onto core planets like Earth. When the flares contact Earth's magnetic field, they may cause relatively severe G2-class geomagnetic storms as well as produce auroras over the poles.

The enormous flare was produced by sunspot AR2936, which has emerged as one of the most active spots on the Sun's surface in the new solar cycle. This sunspot is so large that it can accommodate the entire Earth.

CORONAL MASS EJECTION: WHAT IS IT?

Coronal mass ejection is one of the largest eruptions from the Sun's surface, capable of containing a billion tonnes of stuff propelled into space at speeds of several million miles per hour. This solar material travels through the interplanetary medium, hitting any planet or spacecraft that comes into contact with it. When a particularly powerful CME passes close to Earth, it can destroy satellite electronics and impair radio communication networks on the ground.

The newest CME comes just weeks after Sunspot AR2929 erupted, generating massive M5-class solar flares that ionised the top of Earth's atmosphere, resulting in a shortwave radio blackout in the Indian Ocean.

Active zones, which are locations on the Sun characterised by the presence of high magnetic fields and are frequently linked with sunspot groups, are where solar flares typically occur. These magnetic fields can reach a point of instability and release energy in a variety of ways as they grow.

IS IT GOING TO CAUSE A GEOMAGNETIC STORM?

A geomagnetic storm is a severe disturbance of Earth's magnetosphere that happens when energy from the solar wind is transferred very efficiently into the space environment around the planet.

A geomagnetic storm occurs when a CME collides with the Earth, and the National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Center in the United States has issued a warning about a possible G2 (Moderate) geomagnetic storm.

Multiple SWPC forecasters' calculations suggested a CME speed of 23,83,200 kilometres per hour, according to the agency. "Before Earth's approach, the CME will be spotted by the NOAA DSCOVR spacecraft (approximately 1 million miles distant). A G1 (Minor) geomagnetic storm watch is in effect for 03 February, as any geomagnetic storm conditions are likely to persist at weakening levels "According to the agency.

  Rahul Bajaj, an industrialist and former chairman of the Bajaj Group, died on February 12th. He was 83 years old when he died. "I am writing to notify you that Shri Rahul Bajaj, husband of the late Rupa Bajaj and father of Rajiv/Deepa, Sanjiv/Shefali, and Sunaina/Manish, has passed away. In the presence of his closest family members, he died on the afternoon of February 12th, 2022 "The Bajaj Group issued a statement. Rahul Bajaj had pneumonia as well as a heart condition. Dr. Purvez Grant, the managing trustee at Ruby Hall Clinic, said he had been admitted to the hospital for the past month. Rahul Bajaj passed away at 2.30 p.m. today. Rahul Bajaj, who was born on June 10, 1938, was the chairman of the Bajaj Group for more than 40 years. Rahul Bajaj stepped down as chairman of Bajaj Auto in April of last year and is now Chairman Emeritus of the company. In 2001, Rahul Bajaj received the Padma Bhushan, the third highest civilian honour. Bajaj was also a member of th...

SPACE AGENCY SAYS CHANDRAYAAN-2 ORBITER DETECTS SOLAR PROTON EVENTS ISRO

  Mumbai: The Indian Space Research Organisation (ISRO) announced on Wednesday that the Large Area Soft X-ray Spectrometer (CLASS), a payload on board the Chandrayaan-2 Orbiter, had discovered solar proton events (SPEs), which considerably increase radiation exposure to humans in space. Coronal mass ejections (CMEs), a tremendous torrent of ionised material and magnetic fields that reach Earth a few days later, causing geomagnetic storms and lighting up the polar sky with auroras, were also observed by the sensor on January 18. According to the ISRO, such multi-point measurements helps in the understanding of propagation and its impact on various planetary systems. Solar flares are dramatic explosions that occasionally spew out energetic particles (called Solar Proton Events or SPEs) into interplanetary space when the Sun is active. The majority of these are high-energy protons that have an influence on space systems and increase radiation exposure to astronauts. According ...

  BCCI president and previous India captain Sourav Ganguly has been conceded to a city clinic in the wake of testing positive for COVID-19, the cricket board sources said on Tuesday. Ganguly is two immunized and has been voyaging broadly, participating in every expert movement. The 49-year-old was hurried to a medical clinic late on Monday night as a prudent step later his RT-PCR test brought positive back. "He was taken to Woodlands Nursing Home final evening. He has been given medicine and is as of now steady," a BCCI source, who is monitoring Ganguly's wellbeing, told PTI. Ganguly was conceded to clinic two times recently and went through crisis angioplasty subsequent to having some heart issues. His senior sibling Snehasish Ganguly had additionally tried positive for COVID early this year.
