; Wimbledon has an 11 p.m. curfew.So in Paris, for example, a match can start at 11 a.m. or 8:15 p.m. or anywhere in between — or, occasionally, much later. It is a frustrating aspect of the sport for the athletes or for fans hoping to see a certain player.

has been a hot topic, with questions about why the first match every day in the main stadium — before most spectators have arrived, leaving thousands of empty seats — involves women, and why the popular night session exclusively has gone to men.The primetime slot that hasn’t been offered to any women in Paris since one match in 2023 often means extra attention and exposure.It also can mean staying up past one’s bedtime.

“If I could never play at 1 a.m. ever again for the rest of my life, I would be so happy,” No. 7 seed Keys, a 30-year-old born in Illinois and based in Florida, said with a laugh. “You know when you’re going to go on. There’s no chaos. You go to bed at a totally normal time. I feel like I’ve lived my night-owl life, and I would really love to be that first-on slot for the rest of time.”Other than the initial matches on each court in the morning and at night, it is impossible to know when to warm up and ramp up.

Last spring, the strongest geomagnetic storm in two decades slammed Earth, producing light displays across the Northern Hemisphere. And last fall, a powerful solar storm dazzled skygazers far from the Arctic Circle when dancing lights appeared in unexpected places including Germany, the United Kingdom, New England and New York City.Aurora displays known as the northern and southern lights are commonly visible near the poles, where charged particles from the sun interact with Earth’s atmosphere.

Skygazers are spotting the lights deeper into the United States and Europe because the sun is going through a major facelift. Every 11 years, its poles swap places, causing magnetic twists and tangles along the way.Severe storms are capable of scrambling radio and GPS communications.
