Three image specialists based in the island nation have successfully captured photographs of “red sprites”, one of the least common atmospheric displays on Earth, during which bright red bursts appear in the sky.
The imaging specialists initially planned to capture the night sky over the unique geological structures in the South Island of the country on a night in October, before encountering the extraordinary event.
They thought they would be fortunate to get clear skies that after-dark period, but their night became “a truly memorable experience,” a team member remarked.
“He was checking his photographs for a galaxy composite and discovered he had captured crimson electrical bursts,” the individual said. “It was unbelievable – we experienced screaming and shouting and all sorts going on in the night.”
These crimson flashes are atmospheric energy releases in the mesosphere, produced by electrical storms. Unlike traditional lightning that strikes downward to the ground, these events ascend towards the higher altitudes, producing shapes that look like pillars, root vegetables or even jellyfish. The first photograph of a this phenomenon was recorded – by chance – in 1989, by a research unit at the University of Minnesota.
The phenomena last for such a short time – lasting just a millisecond – that they are seldom seen to the unaided vision, but an individual was fortunate. “I happened to be looking directly at a sprite when it happened – an ideal happenstance observing the correct area of the firmament and I saw a short crimson illumination,” he explained.
Observing the occurrences was a aspiration for the photographer, an award-winning nocturnal imaging specialist. “It looks like you are observing an unreal vision, it appears mystical … there is an intense scarlet hue that is there for a split second, so it is fascinating to witness.”
Capturing a this phenomenon demands a proficiency with technical photography, as well as an knowledge about scientific principles and creative flare, the photographer stated. “This is a highly complex form of imaging that’s very rewarding as well.”
One of the other individuals said it was counted as the “most amazing after-dark experiences” of his life. “I could see the starry river glowing above the horizon while these giant scarlet filaments of energy moved above a electrical event hundreds of kilometres away,” he said.
As far as he knows, there are no additional photographs capturing crimson flashes and the southern hemisphere Milky Way in a single image.
“It was one of those moments when you understand you are observing an event you’ll probably never see again.”
