Since November 22, no sunspots have been observed on the Sun, and NOAA forecasters have classified solar activity as “very low.” Nevertheless, the sky above Tromsø, Norway, exploded with a remarkable surge of pink auroras.
“Suddenly the whole valley became white (with a shade of pink),” said Frank Meisner, who saw and photographed the display.
According to eyewitnesses, they froze in place from the incredible pink and green lights seen in the sky.
This outbreak was caused by a stream of solar wind flowing out of a hole in the Sun’s atmosphere. Such holes are common during the solar minimum, and they do not require the formation of sunspots.
