International Space Station welcomes 2 Saudi astronauts

Mangaluru, May 14: The Met department has sounded a yellow alert in 13 districts of Karnataka including the three coastal districts of Udupi, Dakshina Kannada and Uttara Kannada for next four days. 

The other districts are Belagavi, Dharwad, Haveri, Chikkamagalur, Chitradurga, Hassan, Kodagu, Mandya, Ramanagara, Shivamogga. These districts are expected to received 6-11 cm of rain, the department said.

On Monday Dakshina Kannada and Udupi experienced a monsoon-like atmosphere. Rain, accompanied by thunder and lightning, began in most parts on Sunday evening. In Udupi, rain showered in the early hours of Monday. While Kundapur and Udupi received moderate rains, Karkala experienced a heavy downpour.

The showers lowered the daytime temperature in both districts. Light rain fell in Mangaluru and its outskirts early Monday morning. Mangaluru city recorded a maximum temperature of 33.4°C and a minimum of 23.2°C on Monday. This is expected to decrease by two to four degrees in the next four days, according to the weather department. 

Washington, May 11: The most powerful solar storm in more than two decades struck Earth on Friday, triggering spectacular celestial light shows from Tasmania to Britain -- and threatening possible disruptions to satellites and power grids as it persists into the weekend.

The first of several coronal mass ejections (CMEs) -- expulsions of plasma and magnetic fields from the Sun -- came just after 1600 GMT, according to the National Oceanic and Atmospheric Administration (NOAA)'s Space Weather Prediction Center.

It was later upgraded to an "extreme" geomagnetic storm -- the first since the "Halloween Storms" of October 2003 caused blackouts in Sweden and damaged power infrastructure in South Africa. More CMEs are expected to pummel the planet in the coming days.

Social media lit up with people posting pictures of auroras from northern Europe and Australasia.

"We've just woken the kids to go watch the Northern Lights in the back garden! Clearly visible with the naked eye," Iain Mansfield in Hertford, England, told AFP.

That sense of wonder was shared in Australia's island state of Tasmania.

"Absolutely biblical skies in Tasmania at 4 am this morning. I'm leaving today and knew I could not pass up this opportunity," photographer Sean O' Riordan posted on social media platform X alongside a photo.

Authorities notified satellite operators, airlines, and the power grid to take precautionary steps for potential disruptions caused by changes to Earth's magnetic field.

Elon Musk, whose Starlink satellite internet operator has some 5,000 satellites in low Earth orbit, described the solar storm as the "biggest in a long time."

"Starlink satellites are under a lot of pressure, but holding up so far," Musk posted on his X platform.

Unlike solar flares, which travel at the speed of light and reach Earth in around eight minutes, CMEs travel at a more sedate pace, with officials putting the current average at 800 kilometers (500 miles) per second.

The CMEs emanated from a massive sunspot cluster that is 17 times wider than our planet. The Sun is approaching the peak of an 11-year cycle that brings heightened activity.

'Go outside tonight and look'

Mathew Owens, a professor of space physics at the University of Reading, told AFP that how far the effects would be felt over the planet's northern and southern latitudes would depend on the storm's final strength.

"Go outside tonight and look would be my advice because if you see the aurora, it's quite a spectacular thing," he said. People with eclipse glasses can also look for the sunspot cluster during the day.

In the United States, this could include places such as Northern California and Alabama, officials said.

NOAA's Brent Gordon encouraged the public to try to capture the night sky with phone cameras even if they couldn't see auroras with their naked eyes.

"Just go out your back door and take a picture with the newer cell phones and you'd be amazed at what you see in that picture versus what you see with your eyes."

Spacecraft and pigeons

Fluctuating magnetic fields associated with geomagnetic storms induce currents in long wires, including power lines, which can potentially lead to blackouts. Long pipelines can also become electrified, leading to engineering problems.

Spacecraft are also at risk from high doses of radiation, although the atmosphere prevents this from reaching Earth.

NASA has a dedicated team looking into astronaut safety and can ask astronauts on the International Space Station to move to places within the outpost that are better shielded.

Following one particularly strong flare peak, the US Space Weather Prediction Center said users of high-frequency radio signals "may experience temporary degradation or complete loss of signal on much of the sunlit side of Earth."

Even pigeons and other species that have internal biological compasses could also be affected. Pigeon handlers have noted a reduction in birds coming home during geomagnetic storms, according to NASA's Jet Propulsion Laboratory.

Officials said people should have the normal backup plans in place for power outages, such as having flashlights, batteries, and radios at hand.

The most powerful geomagnetic storm in recorded history, known as the Carrington Event after British astronomer Richard Carrington, occurred in September 1859.

New Delhi, May 5: Actor-turned-politician Kangana Ranaut intended to target an opposition leader but mistakenly ended up attacking her BJP colleague instead. 

A similarity in names - Tejashwi and Tejasvi - was behind Ms Ranaut's fumble. "There's a party of spoilt princes... whether it's Rahul Gandhi who wants to grow potatoes on the Moon, or Tejasvi Surya who does hooliganism and eats fish," she had said.

RJD leader and former Bihar deputy Chief Minister Tejashwi Yadav was supposed to be the original target of her diatribe as one of his videos where he was seen eating fish became a major flashpoint between the BJP and the opposition recently.

Tejasvi Surya, incorrectly referred to by Ms Ranaut during an election rally yesterday, is BJP's Lok Sabha candidate from Bengaluru South constituency in Karnataka.

Meanwhile, Mr Yadav has responded to a clip of Kangana Ranaut's statement. "Ye mohtarma kaun hai?" (Who is this lady?), he posted on X.

Kangana Ranaut has been verbally bashing the Congress party since the BJP fielded her as their Lok Sabha candidate from Himachal Pradesh's Mandi. Congress leaders Vikramaditya Singh - her opponent in Mandi - and Rahul Gandhi have been the main targets on her dartboard.

While addressing a public rally in the Sundernagar area of Mandi Parliamentary Constituency yesterday, Ms Ranaut took a jibe at Mr Singh and Mr Gandhi over dynasty politics and said that both of them have a magic stick for development and talk only about non-practical things.

The Congress hit back saying the 37-year-old actor should first check the facts about her party leaders and speak about dynastic politics. National Media Coordinator for the Congress, Amrit Kaur, also questioned her qualifications on which she got a BJP ticket from Mandi.

The Mandi Lok Sabha constituency will go to polls on June 1, in the seventh phase of the 2024 Lok Sabha elections.
