Hurricane Irma: Floridians watch and wait as the storm is projected to strengthen

  Hurricane Irma: Floridians watch and wait as the storm is projected to strengthen As a powerful hurricane moves across the Atlantic and toward the U.S. mainland, forecasters say it's still too early to know if Central Florida will be affected. Farther east in the Atlantic, though, hurricane watches are in effect for nearly a dozen Caribbean islands as Irma continues its westward track as a Category 3 storm. "It looks ominous when you're looking at a map and see the storm heading this way, but it's a long way out and things could change," said Brooks Tomlin, a meteorologist at Orlando Sentinel news partner Fox 35.

The sun fired off yet another powerful solar flare Sept. 10, its seventh in seven days.

The flare, which peaked at 12:06 EDT (1606 GMT), covered North and South America in high-energy light. The National Oceanic and Atmospheric Administration's Space Weather Prediction Center (SWPC) released a statement that warned of strong, high-frequency radio blackouts and navigation-system disruption, potentially lasting up to an hour.

Puerto Rico declares state of emergency ahead of Hurricane Irma

  Puerto Rico declares state of emergency ahead of Hurricane Irma Puerto Rico Governor Ricardo Rosselló on Monday declared a state of emergency and activated the National Guard in preparation for the landfall of Irma, a dangerous Category 3 hurricane. "Despite the economic challenges Puerto Rico is facing, the approved budget has $15 million for the emergency fund," Rosselló said in a statement.Irma, which is forecast to strengthen on Tuesday night, is set hit the U.S. territory on Wednesday, the U.S. National Hurricane Center said.

Friday's two monster flares came closely on the heels of a moderate M-class eruption and another one that nearly reached X-class status, peaking at M9.4. Powerful X- Flare Erupts From Active Sunspot | Video. Anatomy of Sun Storms & Solar Flares (Infographic).

Like the six other flares observed since Sept. 4, this one came from a sunspot known as Active Region (AR) 2673 , which is currently turning away from Earth and will soon be out of sight.

There are three categories of solar flares, and Sunday's was the highest classification: an "X" event. Two of the other recent flares were also X-class, including Wednesday's (Sept. 6) X9.3 flare, the strongest solar blast in 12 years.

The SWPC's warning also asked astronauts aboard the International Space Station to take special precautions, because they're above most of Earth's atmosphere and therefore are at risk of exposure to harmful radiation. The warning discouraged astronauts from performing spacewalks just after the flare, for example.

The Sun Just Released the Most Powerful Solar Flare in More Than a Decade

  The Sun Just Released the Most Powerful Solar Flare in More Than a Decade Solar flares occur when the sun's magnetic field twists up and reconnects, blasting energy outward that can cause radiation storms in Earth's atmosphere.At 5:10 a.m. EDT (0910 GMT), an X-class solar flare — the most powerful sun-storm category — blasted from a large sunspot on the sun's surface. That flare was the strongest since 2015, at X2.2, but it was dwarfed just 3 hours later, at 8:02 a.m. EDT (1202 GMT), by an X9.3 flare, according to the National Oceanic and Atmospheric Administration's Space Weather Prediction Center (SWPC). The last X9 flare occurred in 2006 (coming in at X9.0).

NASA's sun -watching Solar Dynamics Observatory captured stunning video of the huge solar flare . The flare erupted from a giant active sunspot known as AR 12192 and was classified as an X3.1-class solar storm — one of the most powerful types of solar storms on the sun

Like many powerful flares, Sunday's was accompanied by a coronal mass ejection (CME), a huge cloud of superheated solar plasma that races through space at millions of miles per hour. AR 2673 isn't pointing directly at Earth anymore, but this CME may still give the planet a glancing blow, potentially supercharging the northern lights on Wednesday night (Sept. 13), according to Spaceweather.com.

The solar activity seen this month comes as a bit of a surprise, as the sun is currently entering solar minimum, a quiet portion of the star's roughly 11-year cycle of change.
