A solar eruption is sending particles toward Earth, creating auroras in both hemispheres. The aurora borealis might be visible in the northern US and Scotland on Monday night, while the aurora australis could appear in southern Australia.
The spectacle coincides with a penumbral lunar eclipse, visible globally. Australia’s Bureau of Meteorology (BoM) issued an aurora alert due to a severe solar storm, noting the aurora australis might be seen.
The storm, caused by coronal mass ejections, peaked at 6 on the Kaus Index, meaning auroras might be visible across Tasmania, Victoria’s coast, and Western Australia’s southwest.
A simultaneous lunar eclipse may obscure aurora sightings as the moon dims briefly tonight.Auroras typically occur near the magnetic poles, which differ from the geographic poles. Severe storms can cause auroras to be seen farther from the poles and disrupt power networks and satellites. They also pose radiation risks to astronauts and high-flying aircraft.
A BoM spokesperson highlighted that significant space weather could impact technology and critical infrastructure. Those hoping to see the aurora australis are advised to find a dark location with an unobstructed southern view, ideally between 10 pm and 2 am.
The current solar cycle, which began in 2019, is likely nearing its peak. Astronomer Dr. Stuart Ryder noted that solar activity is expected to increase, with more chances of visible auroras as the cycle progresses. This cycle might peak in 2024, earlier than originally predicted.
At about 7 pm in Sydney and 7:30 pm in Melbourne, the penumbral lunar eclipse will dim the moon. The eclipse will be visible in parts of Europe, the Americas, Asia, and Africa.
Ryder mentioned that the moon might appear darker as it passes through the Earth’s shadow before returning to full brightness, possibly affecting aurora visibility.
