everyone A glimpse of the Northern Lights It begins as a dot on the surface of the Sun, and its activity constantly causes flares and explosions of solar plasma. Scientists say that if predictions are to be believed, the next year and a half will be full of flashes.
In 2019, the Solar Cycle Prediction Panel 25, an international scientific group sponsored by NASA and the National Oceanic and Atmospheric Administration (NOAA) that forecasts sunspot activity, predicted that next year would be below average. The number of sunspots was then estimated at approximately 110-115 at its peak. But updated models show that Solar activity can be much higher.
Auroras more often and in more places
“Solar activity is expected to continue to increase until the fall of 2024, when auroras will be more likely,” says Mark Misch, a scientist at the University of Colorado at Boulder and the National Oceanic and Atmospheric Administration.
Sunspots – Dark, low-temperature, highly magnetic areas on the Sun’s surface – Create space weather when magnetic anomalies hurl particles into space. This activity, called a coronal mass ejection, sends particles more than 94 million kilometers until they find weak spots in Earth’s magnetic field, where the particles collide with the planet’s atmosphere and produce neon colors that light up the sky.
The aurora borealis are best seen near the Earth’s north and south poles The magnetic field is the weakest. However, this year, increased solar activity has expanded the scope of observing this phenomenon.
“Sky watchers are excited”
Space weather is not the only major factor. Misch explains that the autumn and spring equinoxes lead to greater disturbances in the Earth’s magnetic field. – This happens because the direction of the Earth’s magnetic field directs it The part that is sensitive to the sunThis allows cosmic particles to easily reach the Earth’s atmosphere, he explains.
– When there is a significant disturbance in the magnetic field, you are more likely to see the aurora borealis Low latitudes – The world notices. Misch estimates that the probability of aurora borealis will nearly double in the coming days.
Sunspots are one of the longest observed phenomena, with the first mention appearing in 2013 17th century. – Sunspots are our window into the past, thanks to which we can compare current activity with activity from centuries ago – emphasizes Misch.
Echo Richards embodies a personality that is a delightful contradiction: a humble musicaholic who never brags about her expansive knowledge of both classic and contemporary tunes. Infuriatingly modest, one would never know from a mere conversation how deeply entrenched she is in the world of music. This passion seamlessly translates into her problem-solving skills, with Echo often drawing inspiration from melodies and rhythms. A voracious reader, she dives deep into literature, using stories to influence her own hardcore writing. Her spirited advocacy for alcohol isn’t about mere indulgence, but about celebrating life’s poignant moments.
