Nagaland's capital, Kohima, has been placed on high alert after fresh cases of African Swine Fever (ASF) were confirmed. Authorities have declared infected and surveillance zones while banning the movement of pigs, piglets, pork, and pig products to contain the outbreak.
African Swine Fever is a highly contagious viral disease that affects domestic and wild pigs. Although it does not infect humans, it poses a serious threat to the livestock industry and the livelihoods of thousands of pig farmers in Nagaland.

<p>Flares are rated based on their severity, with the weakest being classified as b-class flares and the strongest as x-class flares.</p>

<p>Each letter marks a 10-fold increase in power over the one lower on the scale. Therefore, the latest X7.1 solar flare is extremely strong and has been described as the second most powerful of the current solar cycle.</p>

New York’s sky likely to dazzle with northern lights due to geomagnetic storm

<p>A massive solar flare was detected on the Sun’s surface on New Year’s Eve, prompting space observers to issue a warning to high-frequency radio users. The Space Weather Prediction Center (SWPC) of the National Oceanic and Atmospheric Administration (NOAA) on Sunday (Dec 31) released an image of the flare, which looks like a bright spot on the surface of the Sun.</p>

<p>“A flare is an eruption of energy from the sun that generally lasts minutes to hours,” the SWPC said. The flare spotted on Sunday was categorised as an X5 flare.</p>

<h2><strong>What’s X class flare?</strong></h2>

<p>NASA classifies solar flares based on strength, similar to earthquake categorisation. The scale includes B-class, C-class, M-class, and X-class, with each letter representing a ten-fold increase in energy output.&nbsp;</p>

<p>X-class flares, surpassing 9, can lead to significant impacts, such as radiation storms affecting satellites and causing global transmission issues. The strongest recorded X-class flare was an X45 in 2003.</p>

<p>The recent X5 flare, though smaller than the 2003 record, was the strongest since September 2017. It had the power to affect high-frequency radio signals, causing temporary degradation or loss on the sunlit side of Earth.&nbsp;</p>

Storms of such intensity can cause high-latitude power systems to experience voltage alarms and transformer damage, according to NOAA. It can result in aurora seen as far south as New York and Idaho. As per NASA’s estimates, the geomagnetic storm to strike Earth around mid-Friday, but it could arrive as soon as Thursday. (With inputs from agencies)

'Cannibal' geomagnetic storm to trigger colourful auroras. Here's when to watch

<p><meta name="uuid" content="uuid55FnOSGq1e18" /><meta charset="utf-8" />An aurora dazzled in the skies in India's Ladakh after a severe geomagnetic storm hit Earth. Taking to Twitter, the Indian Institute of Astrophysics (IIA) said last Saturday (April 29) that it captured this phenomenon on a 360-degree camera on April 22-23 night. "This is a time-lapse of the sky taken by a 360 deg camera at from Hanle on 22/23 April night. You can see the aurora lights due to an intense geomagnetic storm that hit the Earth. It is extremely rare to see the aurora at such a low latitude!" the IIA tweeted.&nbsp;</p>

<p>The IIA said that at 11.42 pm on April 21, the sun launched a Coronal Mass Ejection (CME) towards the earth. "This CME (speed of 500-600 km/s) was associated with an M1 class solar flare. The CME arrived at Earth late on April 23 at 10 PM," Wageesh Mishra, a professor at the IIA said.&nbsp;</p>

Aurora dazzles in Ladakh skies after geomagnetic storm hits earth

<p>Earth's magnetosphere was damaged on Monday by a powerful shockwave that entered the planet. According to a report by Space Weather, the mysterious shockwave could lead to a geomagnetic storm as the barrage of plasma smashed into Earth's magnetic field.&nbsp;</p>

<p>For the unversed, the magnetosphere is our planet's protective shield which is created by the magnetic field that protects Earth from harmful radiation.&nbsp;</p>

A powerful shockwave smashed into Earth and cracked magnetosphere

<p>According to the Space Weather Prediction Center of National Oceanic and Atmospheric Administration (NOAA), Earth will be slammed by a geomagnetic storm on Wednesday and Thursday.</p>

<p>It will, however, be a modest one, according to NOAA, which has classified it as G1.</p>

<p>G1 to G5 are the several types of geomagnetic storms, with G5 being the most powerful.</p>

<p>On March 3, a coronal mass ejection from a 25-degree-long filament lifted off the sun, according to NOAA.&nbsp;</p>

<p>In addition to bringing the aurora to higher altitudes, these storms could have an influence on electrical infrastructure, such as power grids and power plants, radio and satellite communications, and navigation systems.</p>

<p>On March 4, a second filament eruption occurred, but it appears that the CME from that event will have little effect on Earth.</p>

Earth is likely to be hit by a geomagnetic storm on April 6-7

<p>Scientists have confirmed that several geomagnetic storms are going to hit Earth this week.</p>

<p>Geomagnetic storms are caused by ejections of the solar corona into space, resulting in disturbances to the Earth's upper atmosphere and increased drag on objects in low orbits.</p>

<p>"There is a chance of enhancements to the auroral oval at times during 13th and 14th March as a result of two Coronal Mass Ejections (CMEs) and a coronal hole high-speed stream arriving at Earth," the British Met Office advised.&nbsp;</p>

<p>The storm, a big cloud of charged particles that will fling from the Sun at about 4.5 million miles per hour (7.2 million km per hour), will be spawned by a pair of solar flares, scientists said.</p>

<p>This is probably the strongest such event in nearly six years, and is likely more intense than a similar storm in late January, said Joseph Kunches, a space weather specialist at the US National Oceanic and Atmospheric Administration (NOAA).</p>

<p>This solar disturbance is a three-stage affair, or as Kunches said in a telephone interview from Boulder, Colorado: “We hit the trifecta.”</p>

<p>In the first stage, two solar flares moving at nearly the speed of light reached Earth late on Tuesday. Such flares can cause radio blackouts.</p>

<p>Then, solar radiation hit Earth’s magnetic field on Wednesday, with possible impact on air traffic, especially near the poles, satellites and any astronauts taking space walks. This phase could last for days.</p>

<p>Finally, the plasma cloud sent by the coronal mass ejection, which is basically a big chunk of the Sun’s atmosphere, is expected to arrive at Earth early on Thursday.</p>
