Nordic landscapes and northern lights – 8

Full spectrum illustrates nicely how visible and infrared aurorae correlate to each other. It seems that infrared emissions lie slighly below the green ones, and are probably in the same region as the visible red emissions. Due to the infrared leak of the blue channel, this results in a white northern light in full spectrum. […]

There are certain wavelength bands that astronomers try to avoid at all cost. At about 800-850nm, the sky has very strong emissions, which adversely affects astronomic imaging, but I wanted to see whether one can see nothern lights in this range as well. As we anchored for a bit, I tried it out and – […]

Here is an illustration of the latter point: in that night, the sky emission was so strong that it can be seen as a red haze even against the other wavelengths. This leads to a second point: as different and diverse nothern lights can be in the visible spectrum, they are just as diverse in […]

This one is my personal favorite from the entire trip. All of the things that make infrared unique are here: the sky emissions make it appear as it was full moon, while the aurora shines in a bronze tone that is utterly different from visible-light photos.

In contrast to its infrared counterpart, the scene is much more evenly lit in full spectrum. The water reflection is particularly interesting, as it would be expected to see higher reflection in the visible spectrum – and indeed, even the colour on the water surface seems to be a bit more green (and therefore more […]

It was a truly magical night, as we crossed the aurora crown and it danced right above us. It was so freezingly cold that only two of us remained, but it was worth it!

The last night of northern lights had a particularly eerie feeling to it, as the aurora was quite faint but very active. The infrared sky emission made itself known again, as well. As before, there is a remarkable difference in water reflections between full spectrum and infrared.

Here, full spectrum truly shows what firework we could see if our eyes had infrared capabilities as well. The sky has a purple taint due to the infrared sky emissions and the horizon again shifts colours due to visible light absorption.

On the last full day, Norway said goodbye with a particularly scenic sun setting above the coastal mountains. I couldn’t be happier with what we have seen and experienced on that voyage.
