For much of mid-October, Earth’s magnetic field has been very quiet, reports Dr Tony Phillips over at spaceweather.com. Extremely quiet. No sunspots. No solar flares. No CMEs. No gust of solar wind.
Such calm space weather conditions should have produced no auroras at all, yet around the Arctic Circle, photographers have been capturing stunning scenes such as this:
Photographer Rayann Elzein of Utsjoki, Finland says he captured similar displays all last week AND through the weekend: “On each occasion geomagnetic activity was very low (with K-indices no greater than 0 or 1).”
Red auroras appear when particles from space strike oxygen atoms near the top of Earth’s atmosphere. However, as Les Cowley explains, the very slow atomic transitions which produce red photons in the aurora zone are easily interrupted — even experienced observers rarely see them.
Elzein has been chasing auroras in Finland for 10 years. He prides himself on going out in all conditions–even when geomagnetic activity is nominally low.
“I can’t recall ever seeing so much red on top of the green layer before,” he says.
In Tromsø, Norway, aurora tour guide Markus Varik had a similar experience.
“Activity was extremely low on Oct 17 when pink and red colors appeared,” says Varik. “After years of guiding, I have never seen anything similar to this.”
The common denominator appears to be … quiet.
“It seems that the red was most apparent during the lowest geomagnetic activity–that is, when Bz was positive and the solar wind speed was slow (at or below 300 km/s),” notes Elzein. “The solar wind was also dense, with proton densities above 15 p/cm3.”
It remains something of a mystery, writes Dr Phillips.
Aurora experts are urged to submit their “red” explanations here.

Both NOAA and NASA appear to agree, if you read between the lines, with NOAA saying we’re entering a ‘full-blown’ Grand Solar Minimum in the late-2020s, and NASA seeing this upcoming solar cycle (25) as “the weakest of the past 200 years”, with the agency correlating previous solar shutdowns to prolonged periods of global cooling here.
Furthermore, we can’t ignore the slew of new scientific papers stating the immense impact The Beaufort Gyre could have on the Gulf Stream, and therefore the climate overall.
Prepare accordingly— learn the facts, relocate if need be, and grow your own.
