"The photograph was taken by photographer Valter Binotto, who watched as the glowing structure flashed in the sky at 10:45 local time on November 17. Strangely, this ring bears a striking resemblance to another red halo that was spotted by Mr Binotto in the same location in March 2023. This year's halo was estimated to be 150 miles (200 kilometres) across and hovered at an altitude of around 60 miles (100 kilometres)."
"Scientists believe that ELVEs are triggered when enormously powerful lightning bolts send an electromagnetic pulse (EMP) shooting through the upper atmosphere. These pulses collide with a part of Earth's atmosphere called the ionosphere, which stretches between 50 and 400 miles (80-644 kilometres) above the ground. Here, the electromagnetic radiation excites charged particles of nitrogen, causing them to give off a red glow. This is a similar process to how electromagnetic radiation from the sun causes the glow of the Northern Lights."
A glowing red halo appeared over Possagno and was photographed by Valter Binotto at 10:45 local time on November 17. The ring closely resembled a similar red halo observed in the same location in March 2023. The phenomenon was estimated to span about 150 miles (200 kilometres) and hover near 60 miles (100 kilometres) altitude. Scientists identify the rings as ELVEs, caused by electromagnetic pulses from powerful lightning colliding with the ionosphere. Excited nitrogen particles in the upper atmosphere emit the red glow. ELVEs last only one thousandth of a second, requiring specialised high-framerate camera setups to capture.
