Piliers de lumière et aurores boréales

Sur cette image, nous voyons deux phénomènes nordiques que nous avons eu la chance de voir au cours de notre séjour en Suède. Les piliers étaient d'abord apparu au zénith, permettant de chouettes compositions, c'est une activité aurorale en éveil qui nous a fait courir jusqu'à ce point de vue pour permettre de réaliser cette image ou les deux phénomènes se rencontrent.
Les piliers de lumière sont des phénomènes provoqués par la réflexion des lumière sur des cristaux de glace. Ici ce sont les passages des camions, sur la route à coté du parc naturel d'Abisko qui provoquent cet effet. Le froid glacial qui règne ici favorise évidemment ce phénomène. A ne pas confondre avec une aurore boréale, que l'on aperçoit bien ici à droite de l'image.
La galaxie d'Andromède, en haut à gauche de l'image complète ce joli tableau.

In this image we see two Nordic phenomena that we had the chance to see during our stay in Sweden. The pillars first appeared at the zenith, allowing for some cool compositions, it was an awakening auroral activity that made us run to this point of view to allow us to create this image where the two phenomena meet.
Pillars of light are phenomena caused by the reflection of light on ice crystals. Here it is the passage of trucks, on the road next to the Abisko natural park which causes this effect. The freezing cold that reigns here obviously favors this phenomenon. Not to be confused with an aurora borealis, which can be clearly seen here to the right of the image.
The Andromeda galaxy, at the top left of the image completes this pretty picture.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
