The solar minimum may be on its way, but as I wrote before in the description of my tours, it does not mean that we will not see Auroras in Inari anymore. Sure, the sun is not covered with sunspots anymore. As a result, there are no big solar flares (eruptions on the sun) to send huge fast quantities of solar plasma into space. This probably means that southern latitudes might see less frequent Auroras. But during solar minimum, coronal holes still occur frequently, creating enough disturbance to spark bright Auroras “under the oval”. Inari is located right under this oval, making it the perfect place to still see bright Auroras even during solar minimum.
What is a coronal hole?
The corona is the scientific word to describe the atmosphere of the sun. Sometimes, gaps, or holes, open in the corona. They are called coronal holes. These openings allow the solar wind to flow freely at a greater speed and density into space. When such a coronal hole faces our planet Earth, this solar wind will eventually reach us and spark Auroras in northern latitudes.
Thursday 15 March 2018 at Solojärvi near Inari
That Thursday I spent the afternoon in the wilderness with reindeer herder Petri Mattus taking photos of his work with the reindeer. This was a perfect coincidence as he lives near the lake Solojärvi, a perfect location to take photos of the Auroras. I wanted to shoot the Aurora on a frozen lake, to have a clear view on the horizon. So just after sunset, I drove there and decided to settle there for the night.
While driving, and despite a still quite bright twilight, I could already see Aurora. I had to hurry to the middle of the lake to get a clear view to the sunset, with the Aurora above the orange glow of the sun.
As you can see, the sky was totally full with Aurora, and there was even already a purple fringe visible! And just 2 minutes later, a corona appeared right above my head.
After this first long outburst of Auroras, the sky kept glowing in a very soft green for more than 3 hours. A group came and walked in the distance along the shore, probably got cold, and disappeared back in their car and away from the lake, because there was almost nothing to see at the time. They missed everything that followed! I knew that it could not just stop there, so I stood there, on my frozen lake, with the temperature plummeting to -30°C (-22°F) as I found out later, waiting for more Auroras. After all, it was my last night of the season in Lapland, so I had enough motivation to see more.
Finally, around 11:30 PM, the sky exploded in the brightest, fastest and most intense greens and purples that I had ever seen. The Aurora was everywhere, and I could barely handle it with my 14mm lens!
By the way, I don’t know how I managed to get from landscape to portrait orientation in literally 24 seconds with my nearly frozen fingers…
Back “home” in Kaamanen
Solojärvi is about a 45 minutes drive away from the cabin where I usually stay in Kaamanen, so around midnight I decided that it was time to start driving, knowing very well that it might lead me to missing a part of the show. The sky was really bright during the entire drive, but luckily it seems that nothing really special happened. Besides, I was constantly in touch on Whatsapp with my friends from Aurora Holidays also not too far away, and I’m pretty sure that my phone would have buzzed a lot if any explosion happened during my drive!
It seems that I arrived just on time in Kaamanen…
About 10 minutes later, the brightest corona of the night appeared right above my head. It was pulsating like I had never seen before.
Last Auroras in Inari in my season
These were the last Auroras in Inari for me this season. This was the most incredible way to end the season. These were also the best Auroras that I have ever seen, all seasons combined, since 6 years that I have been chasing them. That was truly a night to remember! And to think that they were not sparked by a solar flare, but rather a simple (yet big) coronal hole, gives me plenty of hope that we will not really feel the solar minimum in the very north of Finnish Lapland.
I regularly run my own workshops in the north of Finnish Lapland, so why don’t you check out where to go next?
