The aurora is expected to be bright and visible in multiple northern U.S. states Oct. 3 through Oct. 5 as well as from the lower Midwest to Oregon.
Now that the sun is at the height of its 11-year cycle, the increase in solar activity has more frequently fueled "space weather" that produces the right conditions for northern lights to flourish
— NOAA Space Weather Prediction Center (@NWSSWPC) September 11, 2024. ... This article originally appeared on USA TODAY: Northern lights may be visible this week across these 17 states.
The Space Weather Prediction Center (SWPC), named the Space Environment Center (SEC) until 2007, [1] is a laboratory and service center of the US National Weather Service (NWS), part of the National Oceanic and Atmospheric Administration (NOAA), located in Boulder, Colorado. [2]
Sunspot activity has been measured using the Wolf number for about 300 years. This index (also known as the Zürich number) uses both the number of sunspots and the number of sunspot groups to compensate for measurement variations. A 2003 study found that sunspots had been more frequent since the 1940s than in the previous 1150 years. [30]
The Solar Cycle 25 Prediction Panel predicted in December 2019 [11] that solar cycle 25 will be similar to solar cycle 24, with the preceding solar cycle minimum in April 2020 (± 6 months), and the number of sunspots reaching a (smoothed) maximum of 115 in July 2025 (± 8 months).
The northern lights will be visible for parts of the northern U.S., according to the NOAA Space Weather Prediction Center's aurora forecast. The aurora will be visible over much of Canada and ...
Solar Cycle 25 has been ongoing, and scientists with NOAA and Nasa have been tracking sunspots to determine and predict solar activity. The past two years marked the active phase of the solar ...
