A time-lapse of a few nights ago taken by the #meteor camera I have installed on the roof of my institute. Almost every clear night has been full of #aurora the last few weeks

The goal is to install 10-14 of these system across northern #sweden and start catching much more meteors with determined orbits (and ones that were also observed by other instruments) and possibly find #meteorites!

(And as a nice side-effect I get lots of cool videos of aurora and polar stratospheric clouds too)

On the left, the night sky is lit up by particles expelled from the Sun that later collided with Earth's upper atmosphere — creating bright auroras. On the right, the night glows with ground lights reflected by millions of tiny ice crystals falling from the sky — creating light pillars. And in the center, the astrophotographer presents your choices.
The light pillars are vertical columns because the fluttering ice-crystals are mostly flat to the ground, and their colors are those of the ground lights. The auroras cover the sky and ground in the green hue of glowing oxygen, while their transparency is clear because you can see stars right through them. Distant stars dot the background, including bright stars from the iconic constellation of Orion. The featured image was captured in a single exposure two months ago near Kautokeino, Norway.

It was 2:30am. I’d barely slept due to a poorly three year old. But after seeing this through my bedroom window I still got up, got dressed and went out to capture it. #aurora #auroraborealis #northernlights #norrsken

Bright green stripy northern lights above trees.

My polar bear and aurora lightbox for #InterNationalPolarBearDay, a day to focus conservation efforts for these magnificent animals who face habit loss under climate change.

This multimedia light box combines my hand-printed linocut polar bear and aurora print on translucent Japanese kozo (or mulberry) paper 1/2

Multimedia light box with seated polar bear looking at the aurora linocut printed on Japanese kozo (or mulberry) paper with some electronics to make a mesmerizing arctic scene with colour changing Northern Lights.

Powered with a stardard 9V battery an array of self-flashing RGB LEDs provide an ever-changing pattern of light and colour. There’s a narrow white margin, a blue frame with visible silver switch, shot on a white background.

The joy of the unexpected.

Yesterday was by any measure a totally shit day for me. Except for one brief break in the clouds. Metaphorical and literal.

I stepped outside at twilight to watch another aurora, and over the next hour the cloud cover thinned. And it was a marvellous show. I decided to grab a camera and start a timelapse in case more nordlys arrived... and I got lucky

One of the best auroras I've ever seen.

Shining Through

Above the town of Egilsstaðir¹ in eastern #Iceland, the show is beginning.

Amongst the many visible stars there is part of Ursa Major (Great Bear, Plough or Big Dipper) in the upper right and Corona Borealis (The Northern Crown) which looks like a smiley face is centre left.

A colour photo of the night sky with stars. In the bottom left of the shot is a collection of bright streetlights indicating a sizeable town. Rising from the dark hills above the town are two arcs of aurora curving upwards and across the sky. There's a hint of red colour on top of the base of the bands, and some places are slightly brighter green than the rest. A small amount of cloud is covering parts of the streamers but the light is shining through.

Here's a treat for being good this week, a timelapse of the forest last night in Arctic Norway.

There's a very very big mountain to the south of this creek that holds back the clouds. We constantly get long patches of clear sky even when the entire region is clouded over. And sometimes the aurora activity kicks up at the same time. That's a win.

Aurora, somewhere in the highlands of Finland. I think the light pollution actually adds to the photo in this case

A wide angle photo of the Aurora, taken in Finland. Ice and snow are in the foreground. Power lines in the mid-ground, and light pollution on the horizon.

Thank you all so much for your kind birthday wishes! So much genuine affection, I have a little tear in my eye now.
Or perhaps that's just the hangover...

I had a lovely day with lots of phone calls, plenty of laughter and good company. What more could I possibly ask for?

My friends are still here so I must be away and make breakfast.

I leave you with a photo of the #aurora, a lovely image for a lovely bunch of people!

A colour photo of a dark sky full of stars. The foreground is an almost black silhouette with trees. There's a bank of grey cloud running from top centre to bottom left but, peeping from behind it is a beautiful swirl of aurora zigzagging down the shot. Part of it has standing columns in the formation, like a dotted line of bars. It's very green and completely gorgeous.

New on the blog: Auroras Don't Come Easy

"Part of the charm of the Northern Lights is the very fact that they are not easy to capture. Hard enough to plan your travels to be at the right place at the right time, and even then you're often at the limits of your camera gear and your clothing."

Have been digging deep into DxO PhotoLab for my aurora photos and have been amazed just how much better the results are when pushing lenses to the limit.

It handles noise much better than Capture One, while still holding onto detail. And the lens optimisation for my Sigma 14-24mm is just amazing. Never seen such clarity in my night shots before.

Can't believe the software can make such an impact.

Aurora in full moonlight at Grovfjord. A creek spills into the fjord below, while a wave of aurora dances above the village. The moon is bright, just above the nearby peninsula.

Lumix S9 + Sigma 14-24mm F2.8 edited in DxO PhotoLab version 6.

100% pixels from the sky

DxO PhotoLab v6

100% pixels from the terrain. Pretty clear here.

DxO PhotLab v6

Capture One version of same RAW file. 100% pixels showing detail in the terrain. Not so impressive.

#MusicWomenWednesday It was an older KEXP performance where I heard Aurora and her mesmerizing vocals for the first time. Now there is a new one on the KEXP youtube channel, released yesterday
