The best time to view auroras is typically between 10 p.m. and 2 a.m., the Space Weather Prediction Center said. They may be seen earlier but are not as active and visually appealing.
A severe geomagnetic solar storm could bring colorful auroras to the night sky across parts of the nation for a third night in a row. The auroras could be seen as far south as Alabama and west to ...
This is the third geomagnetic storm to reach G4 status during the current 11-year solar cycle, which began in 2019, officials said.
The official planetary K p-index is derived by calculating a weighted average of K-indices from a network of 13 geomagnetic observatories at mid-latitude locations.Since these observatories do not report their data in real-time, various operations centers around the globe estimate the index based on data available from their local network of observatories.
The Space Weather Prediction Center is one of the nine National Centers for Environmental Prediction (NCEP) and provides real-time monitoring and forecasting of solar and geophysical events, conducts research in solar-terrestrial physics (i.e. heliophysics), and develops techniques for forecasting solar and geophysical disturbances.
Such observatories can measure and forecast magnetic conditions such as magnetic storms that sometimes affect communications, electric power, and other human activities. The International Real-time Magnetic Observatory Network , with over 100 interlinked geomagnetic observatories around the world, has been recording the Earth's magnetic field ...
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.
NOAA's Space Weather Prediction Center has issued a geomagnetic storm watch triggered by "coronal mass ejections" that may briefly disrupt satellite communications — and create a stunning aurora ...
