Swedish astrophotographer Göran Strand managed to get not one, but two rare celestial phenomena in one image. The scientist was pleased to photograph the silvery clouds located in the mesosphere – they are higher than any other clouds. At the same time, while shooting near the village of Ostersund in Sweden, Strand noticed the uncharacteristic aurora borealis this season, which he captured together with silvery clouds.
The astrophotographer says he has never seen the aurora borealis so early. “August 8th is actually a new personal record for me,” he explains.
The resulting impressive photo is a panoramic image created from seven photos connected together. It was made at 1:30 a.m. local time. To take photos, the astrophotographer used a Nikon Z9 camera at ISO 1600 and exposure for 5-10 seconds. Additionally, Strand uses data from Aurora satellites to monitor sky activity. And special forecasting applications informed him about the beginning and approximate location of the aurora borealis.
Silvery clouds are considered to be the rarest type of high clouds that can sometimes be seen in the night sky, usually on clear summer nights. According to the Meteorological Bureau, they become visible at about the same time as the brightest stars and usually have a blue or silver color.
