Aurora Alert: Which US states could see the Northern Lights tonight?
The stunning light show has hit the town once again!
Skygazers in America better brace themselves for yet another Aurora Edit, that too – in the middle of the week.
What's happening?
The National Oceanic and Atmospheric Administration (NOAA) has indicated that the northern lights, or aurora borealis, may be observable across several northern US states this week due to ongoing geomagnetic activity.

For Wednesday night, NOAA has predicted a Kp index of four, which is a level that provides opportunities for viewing the lights in certain regions, particularly those with dark and clear skies.
What is the Aurora Borealis?
Aurora borealis, also known as the northern lights, is a natural light display in the sky, primarily seen in high-latitude regions. It occurs when charged particles from the sun interact with the Earth's atmosphere, producing vibrant colors like green, red, and purple.
The aurora borealis is caused by charged particles, mainly electrons and protons, from the sun's solar wind colliding with Earth's magnetosphere. These particles are then guided towards the poles by Earth's magnetic field.
The colors observed in the aurora are determined by the specific atmospheric gases and the energy of the colliding particles. Green light is often associated with oxygen, while red light is also produced by oxygen, and blue and purple light can be seen with hydrogen and helium.
Although the aurora borealis is most frequently observed in regions around the Arctic Circle, including countries like Norway, Sweden, Finland, Iceland, Canada, and Alaska, this time several US states are set to witness the magic as well.
Which US states can watch the Northern Lights?
This forecast follows a period of heightened activity on Tuesday night, when the Kp index reached five, allowing visibility of the aurora in parts of Wyoming, Iowa, Vermont, New Hampshire, and New York, as reported by Forbes.

For those seeking the best viewing opportunities in the United States on Wednesday, Alaska and northern Canada remain the top locations. Within the US, states such as northeastern Washington, northern Idaho, Montana, North Dakota, northern Minnesota, and Michigan's Upper Peninsula offer the highest chances. There is also a slight possibility of visibility in areas of South Dakota, Wisconsin, and Maine.
When can you see the Northern Lights?
The optimal time for observation is between 10 p.m. and 2 a.m. local time. NOAA recommends selecting a high, north-facing location away from city lights for the best experience. For those wishing to take photographs, enabling night mode and disabling the flash on mobile devices is suggested.
Additionally, NOAA has alerted that minor to moderate radio blackouts may occur through Friday, although major disruptions are not anticipated.

‘Sledgehammer attack on Science': South Florida meteorologist warns of hurricane forecast inaccuracies, blames weather agency staff cuts
South Florida meteorologist warns he might not able to predict hurricanes accurately in future A South Florida weather expert told his audience alleging the negative the impact of National Weather Service (NWS) personnel shortages on forecast accuracy. During a broadcast, earlier this week, on NBC affiliate WTVJ, meteorologist John Morales reflected on his 2019 hurricane coverage, stating, "confidently, I went on TV, and I told you, 'It's going to turn. You don't need to worry; it is going to turn.'" Then he expressed concerns about current capabilities, saying, "And I am here to tell you, that I am not sure I can do that this year, because of the cuts, the gutting, the sledgehammer attack on science in general." Morales highlighted specific staffing issues, saying, "And this is a multi generational impact on science in this country. All right, but specifically, let's talk about the federal government cuts to the National Weather Service and to NOAA. Did you know that Central and South Florida National Weather Service offices are currently basically 20 to 40% understaffed from Tampa to Key west, including the Miami office, 20 to 40% understaffed. Now, this type of staffing shortage is having impacts across the nation because there's been a nearly 20% reduction in weather balloon releases, launches that carry those radiosondes. And what we're starting to see is that the quality of the forecasts is becoming degraded." Earlier this year, the Department of Government Efficiency, under Elon Musk's leadership (who has now stepped down from the role), implemented severe reductions at NWS and NOAA, organisations responsible for delivering daily weather forecasts, immediate storm alerts, climate surveillance and tracking extreme weather conditions. In February, the agency dismissed hundreds of weather forecasters and placed other federal NOAA staff on probation, followed by additional staff reductions exceeding 1,000 positions. By April, approximately 20 percent of positions remained unfilled across nearly half of the NWS forecast facilities. However, The Hill's Monday report indicated NWS's intention to recruit 126 new staff following substantial workforce reductions. The National Oceanic and Atmospheric Administration (NOAA), NWS's parent organisation, had previously reduced staff numbers as part of government downsizing efforts. Florida and other southeastern US states face regular Atlantic hurricane threats, with the season commencing Sunday. NOAA responded on Tuesday via email to The Hill, stating, "NOAA leadership is taking steps to address those who took a voluntary early retirement option. NWS continues to conduct short-term Temporary Duty assignments (TDYs), and is in the process of conducting a series of Reassignment Opportunity Notices (RONs) to fill roles at NWS field locations with the greatest operational need."

Asteroid Larger Than Golden Gate Bridge Approaches Earth. What To Know
New Delhi: A massive asteroid, expected to be larger than San Francisco's Golden Gate Bridge, will pass close to Earth on June 5. Measuring between 1,017 and 2,264 feet, it is bigger than 97 per cent of asteroids and is among the top 3 per cent by size. According to scientists, Asteroid 424482 (2008 DG5) is estimated to come to around 3.49 million kilometres of earth but does not pose any threat. It will safely pass by without causing any damage, Forbes reported. The reason the asteroid doesn't pose any threat to the Earth is that it is about nine times farther away than the Moon, which normally orbits Earth at around 3.84 kilometres. However, NASA has referred to the 2008 DG5 as a potentially hazardous object for two characteristics: distance and size. NASA said that any object, larger than about 500 meters, which comes within 7.5 kilometres of Earth could collide with our planet. As of now, there is no threat from 2008 DG5 to Earth but if an asteroid of this size hits, it can cause serious regional damage. It could create strong shockwaves and even tsunamis if it hit water. For example, in 2008, a Tunguska Event happened when a smaller asteroid of about 130 ft exploded in the air over Siberia, causing massive fires and destroying 80 million trees. Other than this, the Chicxulub asteroid, believed to have contributed to the extinction of the dinosaur, was six to ten miles (10 to 15 kilometres) wide. 2008 DG5 is an Apollo asteroid, meaning it passes through Earth's orbit. It was spotted in 2008 by the Catalina Sky Survey, a component of NASA's Near Earth Object Observation Program, near Tucson, Arizona. It completes one round around the sun every 514 Earth days. It will come close to Earth again in the year 2032. Earlier, NASA reported that asteroid 2024 YR4, about the size of the Statue of Liberty, might cause damage to the Earth. It has the potential to release energy 100 times more powerful than the Hiroshima bomb if it hits Earth.

Hurricane season begins: Are FEMA and NOAA prepared amid staffing cuts and FEMA chief's 'unaware' remark?
The Federal Emergency Management Agency (FEMA), responsible for responding to emergency situations, and the National Oceanic and Atmospheric Administration (NOAA), tasked with tracking weather conditions to predict hurricanes, have suffered dramatic cuts from the federal government at the start of the hurricane season from June 1. Concerns have risen about the lack of preparedness of these agencies to predict and tackle hurricanes in advance due to a general lack of resources. Ever since President Donald Trump took office in January, the Department of Government Efficiency (DoGE) has severely pulled back on funding given to organizations crucial in tracking and dealing with climate catastrophes along the coast. This has resulted in several staff cuts, restrictions on travel and training, and a drain of experienced professionals capable of dealing with worst-case scenarios. 'My nightmare is a major catastrophic storm hitting an area that is reeling from the impact of all of this nonsense from the Trump administration and people will die. And that could happen in Florida, that could happen in Texas, that could happen in South Carolina,' said Susan Cutter, the director of the Hazards and Vulnerability Research Institute at the University of South Carolina, in a statement to the Associated Press. Out of the 122 offices of the National Weather Service (NWS), 8 are down by more than 35% in staffing. Around 2,000 people from the full-time staff at FEMA have left the agency since Trump took office leading experts to raise concern over 'brain drain' in crucial agencies. Several emergency management training sessions have either been canceled or moved online this year. Many attendees' travel to the National Hurricane Conference was restricted this year. The launch of weather balloons, which are crucial for understanding the flow of currents and predicting storms about to hit the US, has been restricted due to lack of staffing. Former NOAA meteorologist Jeff Masters, now at Yale Climate Connections, said to the Associated Press, 'Hurricane forecasts, I'm expecting not to be as accurate this year because of that lack of balloon data.' The government has responded to such criticism by reasserting that all agencies are fully capable of dealing with any disasters and the move is meant to give individual states more responsibility in addressing local catastrophes. 'FEMA is shifting from bloated DC-centric dead weight to a lean, deployable disaster force that empowers state actors to provide relief for their citizens,' Associate FEMA Administrator Geoff Harbaugh said to the Associated Press. Only the National Hurricane Center, which is responsible for tracking developments in the Atlantic, Pacific, and Caribbean, has been spared by the administration and is running at full staff capacity. The agencies are also incorporating artificial intelligence into their tracking systems this year for more accurate predictions. No additional budgeting has been provided to states to help them deal with local disasters. Local agencies like the Mississippi Emergency Management Agency have started to take matters into their own hands. 'We have just opened our 10th, about to open our 11th DRC, Disaster Recovery Centers,' said Scott Simmons, chief communications officer for the MEMA. 'FEMA has sent just shy of 300 people to the state of Mississippi to help residents apply for what needs to be done in the wake of that storm system.' Short-term duty assignments and reassignments are being used by the NWS to fill staffing gaps. Amid rising concerns over national agencies' disaster-management capabilities, a statement made by Acting Chief of FEMA, David Richardson, has sent alarm bells ringing. Many staffers and interagency partners who attended Monday's (June 2) daily operational briefing reported Richardson expressing his unawareness about the fact that the US had a hurricane season. Though many were left puzzled by whether he meant it as a fact or joke, most people expressed that the chief genuinely seemed to be in a state of shock. The DHS tried to defend Richardson with a public statement that said, 'Despite meanspirited attempts to falsely frame a joke as policy, there is no uncertainty about what FEMA will be doing this Hurricane Season. FEMA is laser-focused on disaster response, and protecting the American people.' Richardson is a former Marine Corps officer who served overseas and was the Department of Homeland Security's (DHS) assistant secretary in dealing with weapons of mass destruction. He has no direct experience in dealing with high-stakes catastrophes. Despite these developments, representatives of the FEMA and NOAA say they are prepared to deal with any catastrophe.
