What's Happening?
The National Oceanic and Atmospheric Administration (NOAA) has issued a G4 (severe) geomagnetic storm watch due to an Earth-directed coronal mass ejection (CME) from the sun. The CME, launched on January 18, is expected to arrive as early as late January 19
Eastern time, potentially causing auroras visible in 24 U.S. states. The storm levels could range from minor to strong, with the possibility of intensifying. Meteorologists suggest that the best viewing times for the northern lights in Utah are between 11 p.m. and 2 a.m. local time. The visibility of the auroras depends on the CME's magnetic orientation upon arrival.
Why It's Important?
The potential visibility of the northern lights in areas as far south as Colorado is a rare event, offering a unique opportunity for skywatchers and photographers. This event underscores the impact of solar activity on Earth's geomagnetic environment, which can affect satellite operations, power grids, and communication systems. The public interest in such natural phenomena can also boost local tourism and community engagement in science and astronomy. Understanding and predicting space weather events are crucial for mitigating their effects on technology and infrastructure.
