Key Facts
A Kp index of four on a scale of nine was forecast by NOAA for Wednesday night, meaning the northern lights may appear brighter and be more active farther from the poles.
Wednesday's auroral forecast follows a period of 'minor' to 'moderate' geomagnetic storms late Tuesday and early Wednesday, though similar geomagnetic activity is not forecast for Wednesday night, according to NOAA.
Calmer auroral activity is forecast through Friday night, NOAA's three-day forecast suggests, with a maximum Kp index of three and just over two projected for Friday and Saturday nights, respectively.
Where Will The Northern Lights Be Visible?
Northern Canada and Alaska will have a higher likelihood of viewing the northern lights, once the sun sets in the state. A lesser chance is forecast for parts of Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Upper Michigan and Maine. (See map below.)

What's The Best Way To See The Northern Lights?
It's recommended to travel to a north-facing, high vantage point away from light pollution sometime between 10 p.m. and 2 a.m. local time, according to NOAA.
What's The Best Way To Photograph The Northern Lights?
If using a regular camera, it's best to use a wide-angle lens, an aperture or F-stop of four or less and a focus set to the furthest possible setting, photography experts told National Geographic. NOAA also recommends using a tripod to stabilize the image, and if using a smartphone, to disable flash and enable night mode.
Key Background
The northern lights have been increasingly visible in recent months after activity on the sun's surface reached a 'solar maximum.' This peak, occurring throughout the sun's 11-year cycle, corresponds with a rise in solar events like coronal mass ejections and solar flares. These events are largely responsible for creating aurora borealis, as molecules of oxygen and nitrogen in the Earth's atmosphere collide with electrons, causing them to become 'excited' before releasing colorful, swirling displays. A recent peak in activity is projected to persist through early 2026, according to estimates from NOAA and NASA.

Dangerous heat dome begins baking more than 125 million across Southeast
July will make a potentially record-breaking exit this week as a heat dome will create triple-digit feels-like temperatures for millions from Florida to Virginia, prompting heat alerts across the East Coast. A massive "dome" of high pressure known as a heat dome continues to shift extreme temperatures around the U.s. Now, it's the Southeast feeling the heat. On Sunday, areas from southern Georgia to southeastern Virginia will feel the most oppressive heat, where Extreme Heat Warnings are in place. "We are dealing with a lot of heat alerts once again, Extreme Heat Warnings over into the Carolinas for (Sunday), once again, as well as a bit into Florida. That's where the extreme heat is going to be kind of parking itself today, tomorrow, and potentially even into Wednesday," FOX Weather Meteorologist Bayne Froney said. Monday will be the most brutal day, with record highs possible and an extreme heat risk for more than 30 million people, according to Noaa and the Centers for Disease Control and Prevention's HeatRisk forecast. According to the FOX Forecast Center, high temperatures will be in the upper 90s and lower 100s, with heat indices as high as 120 degrees. Areas across the Southeast could see record-high temperatures. If Charlotte, North Carolina, hits 100 degrees, it will be the first time in 20 years. Nashville, Tennessee, and Jacksonville, Florida, could also surpass 100 degrees this week. In the Carolinas, heat advisories were expanded on Sunday to include most areas east of the mountains. City of Charlotte and Mecklenburg County officials are warning residents and visitors to stay cool and safe. "If you are out and about, be sure to find air-conditioned spaces, wear loose-fitting clothing, drink plenty of fluids, and avoid the midday heat," County officials wrote on Facebook this weekend. Cooling centers are open at Senior Centers and some Charlotte-Mecklenburg library locations. For once, South Florida is the only part of Florida not included in heat alerts lasting through Tuesday. The heat will build early this week, with highs for Orlando flirting with triple digits by Tuesday. Record-breaking temperatures continued to hit new highs on Sunday. Tampa soared to 100 degrees by 3:30 p.m., breaking the Florida city's all-time record-high temperature since record-keeping began in 1890. For the Southeast, heat relief won't arrive until next weekend, with the highest temperatures expected through midweek. Froney said this area of high pressure packing extreme heat will next move back toward the western U.S. "We've been talking about this for about a week now. Just a couple of days ago, it was over the Northeast. Now it's shifted back south. It's going to move back towards the west in the coming days," she said. With extreme heat in the forecast, anyone spending time outdoors should take steps to avoid heat exhaustion and heatstroke. Young children and babies, along with older adults, should avoid prolonged time outdoors. When outdoors, it's important to drink plenty of water with electrolytes and spend time in the shade. For your pets, if the sidewalk or road is too hot for your hands after several seconds, it's too hot for your dogs to be walking article source: Dangerous heat dome begins baking more than 125 million across Southeast Solve the daily Crossword

Four killed as heavy rain, flooding soaks northern China
Heavy rains that have soaked swathes of northern China killed four people and left eight missing on Monday, state media said, as downpours force thousands to evacuate across the capital city and surrounding areas. Authorities in Beijing have issued the country's second-highest warning for rainstorms and the highest for floods, with the downpours expected to last into Tuesday morning. In Hebei province, which encircles the capital, the heavy rains caused a landslide in a village near the city of Chengde, state broadcaster CCTV said. Four were killed and eight are still missing, it said, with the national emergency management department dispatching a team to inspect the "severe" flooding in the province, where a further two died over the weekend. Over 4,600 people were evacuated over the weekend in Fuping County, while in neighbouring Shanxi province, one person was rescued and 13 were missing after a bus accident, state media said. Footage from the broadcaster showed roads in the province and a crop field submerged in rushing water on Sunday. In Beijing, over 4,000 people in suburban Miyun district were evacuated due to torrential rains. The area's reservoir "recorded its largest inflow flood" since it was built more than six decades ago, state media reported. On Monday in Mujiayu, a town just south of that reservoir, AFP journalists saw the reservoir release a torrent of water. Power lines had been swept away by muddy currents while military vehicles and ambulances ploughed through flooded streets. A river had burst its banks, sweeping away trees, while fields of crops were inundated with water. Some roads were badly damaged, with chunks of exposed concrete scattered across lanes and twisted guardrails lining their sides. The low-rise houses in the mountainous area, though mostly intact, were surrounded by gushing floods. - Extreme weather - China's National Development and Reform Commission has allocated 50 million yuan ($7 million) to assist relief efforts in Hebei, with the funds going to post-disaster emergency recovery and construction of infrastructure, Xinhua news agency said. Natural disasters are common across China, particularly in the summer when some regions experience heavy rain while others bake in searing heatwaves. China is the world's biggest emitter of the greenhouse gases that scientists say drive climate change and contribute to making extreme weather more frequent and intense. But it is also a global renewable energy powerhouse that aims to make its massive economy carbon-neutral by 2060. Flash floods in eastern China's Shandong province killed two people and left 10 missing this month. A landslide on a highway in Sichuan province this month also killed five people after it swept several cars down a mountainside. bur-mya-isk/oho/jfx

Michigan among states that could glimpse northern lights. See map
Much of Michigan could see the northern lights on July 26, according to NOAA's Space Weather Prediction Center (SWPC) forecast. The northern lights, also known as the aurora borealis, may be visible in as many as 14 northern states tonight, according to NOAA's SWPC dashboard. According to NOAA, "view lines" Michiganders as far south as Grand Rapids, Lansing and Port Huron may be able to catch a glimpse of the shimmering lights in the night sky to the north. The lights could be overhead for people in parts of the Upper Peninsula. NOAA says a G1 geomagnetic storm, a worldwide disturbance of the Earth's magnetic field, is expected to produce a Kp rating of 5. Kp is an index used to indicate the severity of the global magnetic disturbances in near-Earth space, NOAA said. Kp ratings increase from zero to 9+. NOAA is predicting moderate and minor geomagnetic storm impacts. Some high latitude electrical systems could suffer damage, radios could be affected among other issues. When could the northern lights be visible? The northern lights could be visible in Michigan Saturday, July 26, according to SPWC. What are the northern lights? The northern lights, or aurora borealis, are waves of light created when the solar wind strikes the atmosphere, creating a display of moving lights in the night sky. Which states could see the northern lights? The NOAA says the red "view line" marks the southernmost extent where aurora might be seen on the northern horizon. While more than a dozen states have a chance to see the northern lights on July 26, Alaska has the greatest chance to see the spectacle, followed by parts of the following states: Idaho Michigan Washington Montana Wyoming North Dakota South Dakota Minnesota Wisconsin New York Vermont New Hampshire Maine Why do the northern lights have different colors? The color of the aurora depends on which gas is being excited by the electrons and on how much energy is being exchanged, NASA said. Oxygen emits either a greenish-yellow light (the most familiar color of the aurora) or a red light; nitrogen generally gives off a blue light. The oxygen and nitrogen molecules also emit ultraviolet light, which can only be detected by special cameras on satellites.
