Geomagnetic Storm Watch issued with Northern Lights possible from New York to Washington state
NEW YORK – While the ground may feel like it's on fire as a heat dome continues to scorch the U.S. this week, the sky could resemble dancing flames Wednesday night and early Thursday as charged particles from the Sun are barreling toward our planet, creating the chance to see the Northern Lights.
Forecasters with NOAA's Space Weather Prediction Center (SWPC) have been monitoring a feature on the Sun known as a coronal hole – areas on the surface of the Sun with cooler, less dense plasma. These dark areas on the Sun, as seen in satellite images, can produce space weather events known as coronal hole high-speed streams (CH HSS), which can trigger Northern Lights on Earth.
Due to the recurrent, negative polarity CH HSS influence, NOAA space weather forecasts are predicting minor (G1) to moderate (G2) geomagnetic storming between Wednesday and Thursday, based on NOAA's five-level scale. A Geomagnetic Storm Watch is in place through Thursday.
What Causes The Northern Lights?
Under these conditions, the Aurora Borealis may be seen across the northern tier of the U.S. and the Upper Midwest, in areas as far south as New York to Wisconsin to Washington state.
If you're within the Northern Lights viewing area on late Wednesday or early Thursday, a dark sky will help your chances of seeing the bright dancing lights in the sky.
Move away from city lights or turn off artificial light sources outside and look north. Even if you can't see the lights with the naked eye, use your smartphone's night mode, and you might be surprised by what you see. During severe (G4) Geomagnetic Storms, the lights could be seen as far south as the Gulf Coast.Original article source: Geomagnetic Storm Watch issued with Northern Lights possible from New York to Washington state

Vital hurricane satellites to go dark weeks into Atlantic storm season— and NOAA rips media for causing panic
Vital hurricane-tracking satellites are expected to go dark just weeks into the Atlantic storm season — and the National Oceanic and Atmospheric Administration is pointing fingers at the media for fueling panic behind the shutdown while clarifying that crucial data will still be gathered. The Defense Meteorological Satellite Program (DMSP), jointly owned by NOAA and the Department of Defense and responsible for critical collecting environmental and weather data, will cease operations Monday amid a string of federal cuts to the administration, the agency announced Wednesday. 'The service change and termination will be permanent,' officials stated in the announcement without providing a reason for ending the crucial service or information about a possible replacement. Advertisement 4 A NOAA spokesperson clarified that a microwave instrument on another satellite will still provide crucial readings. REUTERS A NOAA spokesperson, however, was quick to cast blame on newscasters for 'criticizing' scientists and reporting the service change in a way that could incite public outrage — later clarifying that a microwave instrument on another satellite will still provide crucial readings. 'The DMSP is a single dataset in a robust suit of hurricane forecasting and modeling tools in the NWS portfolio, which also includes microwave sensing data via the recently launched WSF-M satellite, which was the planned replacement for the DPSM program,' Kim Doster told The Post Friday.

Forecasters depend on polar-orbiting satellites equipped with microwave sensors to track winds speeds and other data connected to intensifying tropical storms and hurricanes — especially at night when other observation methods are limited. Advertisement 'This is an incredibly big hit for hurricane forecasts, and for the tens of millions of Americans who live in hurricane-prone areas,' Michael Lowry, a hurricane specialist in South Florida, told the New York Times. 4 While the military satellites with remain in orbit, their data will not longer be processed by the federal government. REUTERS 'The nightmare scenario is going to bed with a tropical storm and waking up to a hurricane,' he added, explaining that soon-to-be suspended satellite streams are key to preventing a jarring 'sunrise surprise.' With microwave observations also allow meteorologists to locate a storm's center, Lowry warned that being off by even a few miles can have 'huge ramifications.'

AFP /AFP via Getty Images 'We don't want to have less data for no reason,' Andy Hazelton, a hurricane modeling expert at the University of Miami, told the outlet. 'We already don't get as much microwave data as we'd like to see operationally.' The news of the program's suspension came just two days after Tropical Storm Andrea, the first named storm of the 2025 Atlantic hurricane season, formed in the central Atlantic Ocean Tuesday morning. Hurricane season typically lasts through the end of November. The White House and Department of Defense did not immediately respond to The Post's request for comment.

Rare daytime fireball bright enough to be seen from orbit may have punched a hole in a house in Georgia
When you buy through links on our articles, Future and its syndication partners may earn a commission. A large meteor that triggered a spectacular daytime fireball over the southeastern U.S. may have survived its dramatic passage through Earth's atmosphere to punch through the roof of a Georgia home. The fireball was spotted over the southeastern U.S. at 12:25 EDT on Friday, (1625 GMT), visibly flaring as the extreme heat of atmospheric friction overwhelmed the ancient chunk of solar system debris. Its descent was bright enough to be seen by the National Oceanic and Atmospheric Administration's (NOAAs) GOES-19 Earth observation satellite, using an instrument designed to map flashes of lightning from orbit. "Daylight fireballs are rare in that it takes a large object (larger than a beachball compared to your normal pea-sized meteor) to be bright enough to be seen during the day," said Robert Lunsford of the American Meteor Association in an email to "We probably only average one per month worldwide, so perhaps one out of every 3,000 reports occurs during the day." The meteor was first spotted 48 miles (77 kilometers) above the town of Oxford, Georgia travelling at around 30,000 mph (48,000 km/h), according to NASA Meteoroid Environment Office lead Bill Cooke, via CBS News. Lunsford noted that the fireball may have been associated with the daylight beta Taurid shower, which peaks in late June as Earth passes through the trail of cosmic debris shed by the ancient solar system comet 2P/Encke. Footage of the event led many to speculate that fragments of the meteor may have survived its bruising passage through Earth's atmosphere. The hours that followed saw photos circulate online purporting to show the damage that a fragment of the meteorite caused when it smashed through the roof of a home in Henry County, Georgia. "Being much larger than your average meteor also means that it has a better chance of producing fragments on the ground," explained Lunsford "We look for reports of sound such as thunder or sonic booms to have confidence that fragments of the original fireball survived down to the lower atmosphere and perhaps all the way to the ground. Therefore the photograph of the hole in the roof is probably associated with this fireball." If verified, the Georgia meteorite certainly wouldn't represent the first time that a daylight beta Daylight Taurid left a mark on our planet. Lunsford noted that a particularly large meteor that some scientists believe to be associated with the annual shower detonated in a powerful airburst 6 miles (9.6 kilometers) over Russian Siberia in June 1908. The force of the explosion sparked massive forest fires and flattened roughly 80 million trees in what has since become known as the 'Tunguska Event'.

Will northern lights be visible from the U.S. this weekend? See aurora borealis livestreams
The northern lights have been visible in some northern U.S. states this week, and will continue to be visible in Alaska through the weekend. It might sound crazy, but they have been visible from Florida before as well. The most recent sighting of the aurora borealis in Florida was actually last summer. But based on this weekend's aurora borealis prediction, Floridians will have to access a northern lights livestream on YouTube to get a glimpse of the phenomenon. Here's where the northern lights are predicted to be visible this weekend, tips for viewing them, the last time aurora borealis were seen in Florida and how to find northern lights livestreams. During the week, the northern lights could be seen from as many as 14 U.S. states near Canada. There could still be chances to spot the lights from the U.S. this weekend, but the probability of seeing the aurora borealis from any U.S. state outside of Alaska is still low. 'Fast solar wind from a coronal hole is currently sweeping past Earth, bringing a continued chance of possible G1 (Minor) geomagnetic storm conditions through Friday night (June 27). That means auroras could make a brief appearance at high latitudes,' Friday forecast says. 'If you're in the right place tonight and have clear, dark skies, it's worth keeping an eye on the horizon — the auroras might still make a fleeting appearance.' So, where is the right place? NOAA's weekend forecast map shows Alaska well within the range of viewing this weekend and the northernmost parts of some states reaching slightly into the view line on the night of Friday, June 27. The three states that appear to have the best chance of catching a glimpse, based on NOAA's prediction map for Friday, are Montana, North Dakota, and Minnesota. If you're visiting or flying over one of these states this weekend, it's worth trying to find the aurora borealis in the night sky. If you're anywhere else in the U.S., your best shot is to pull up a livestream of the northern lights. NOAA tracks the northern lights and indicates how visible they are predicted to be by using the Kp-index, a global measure of auroral activity. The index is a 0-9 scale and measures changes in the Earth's magnetic field, to predict geomagnetic storms on the sun's surface, which can cause a disturbance in the Earth's atmosphere. NOAA predicts that the Kp index will peak at 3.67 this weekend, the weekend of Friday, June 27. Earlier this week, when more than a dozen states had a chance to see the aurora borealis, the Kp was predicted to peak at around 5. More on northern lights in the U.S.: See which states saw the aurora borealis this week If do you find yourself in the northernmost portions of a state that borders Canada, or in Alaska this weekend, there are ways to increase your chances of spotting auroras. Here are some tips for spotting northern lights, : Be aware of geomagnetic activity: If the geomagnetic field is active, then the aurora will be brighter and further from the poles. Geomagnetic activity is driven by solar activity and solar coronal holes and thus it waxes and wanes with time. For Kp in the range of 3 to 5: the aurora will move further from the poles, it will become brighter and there will be more auroral activity (motion and formations). If you are in the right place, these aurora can be quite pleasing to look at. Location: Find a place where you can see to the north. Given the right vantage point, say for example on top of a hill in the northern hemisphere with an unobstructed view toward the north, a person can see aurora even when it is 1000 km (600 miles) further north. Note: If you are in the right place under the aurora, you can see very nice auroral displays even with low geomagnetic activity (Kp = 3 or 4). It must be dark: Go out at night. Get away from city lights. The full moon will also diminish the apparent brightness of the aurora (not the actual brightness). One caveat that people often neglect to think of is that the high latitudes where aurora occur are also latitudes where it doesn't get dark in the summer. So combining a summer vacation to the arctic with aurora watching usually doesn't work. The aurora may still be there, but it is only visible when it is dark. Timing: Best aurora is usually within an hour or two of midnight (between 10 p.m. and 2 a.m. local time). These hours of active aurora expand towards evening and morning as the level of geomagnetic activity increases. There may be aurora in the evening and morning but it is usually not as active and therefore, not as visually appealing. Best seasons for aurora watching: The best times of year to see the northern lights are around the spring and fall equinoxes. Due to subtleties in the way the solar wind interacts with Earth's magnetosphere, there is a tendency towards larger geomagnetic storms and better auroras to occur near the equinoxes. Yes! Northern lights, or aurora borealis, have been visible as far south as Florida, most recently in May 2024. 'A spectacular and rare sight was visible across Florida on May 10, 2024,' The Florida Times-Union reported. 'The aurora borealis, or northern lights, left many watchers in awe as pink and purple hues painted the night sky.' There are three other significant recordings of northern lights being visible in Florida, two in the '80s and once in the 1850s. In March of 1989, the aurora borealis was visible from Jacksonville, painting the sky with a red glow and streaks of green and white, according to the Florida Times-Union. A few years earlier, in 1981, there were reports of much less impressive northern lights visible as far as south Florida. And according to NOAA, the Carrington Event of 1859 tinted the sky bright red and green, which may have been the most powerful solar flare on record. If you have northern lights FOMO (fear of missing out), you don't have to catch a last-minute flight to Alaska to get your fix this weekend. There are several webcams across the world that livestream the aurora borealis. Links to cameras set up in Sweden, Finland, Norway, Canada and Alaska can all be found on aurora borealis webcam landing page. You can watch the view of the aurora borealis from the University of Alaska Fairbanks on the YouTube channel — a network of nature cameras from all over the world.
