Nice one.
I guess you can get the answer by checking Red, Blue and Green channels separately.

Hello there Carl, thank you for your answer. Indeed, this amount of "yellow" light in the image cannot just come from light pollution, or I would have got it, a priori, also on many occasions before. And when looking at most some airglow "filming" from ISS (1) , yellow light seem...

This was a real clear filter (MC-Clear from Astronomik)
But the white balance is maybe not the best one for night landscape.

I provided one raw file on the shared folder , at the apex of the phenomenon, if you want to try other color temperature and green gain.

Nicolas

Hi Nicolas, the link you provided apparently requires an OK from you to be accessed. In case you get an inquiry from just a few minutes ago, it's from me :) Done. And I re-set in order that anyone could see the files now. Although I have full spectrum cameras for astronomy, for airglow I use my nor...

Hi Nicolas, interesting airglow movement direction. I have never seen this fanning effect before. I always record airglow looking north, because the other directions are too light polluted where I live (50.2°N, 8.3°E). And there the airglow typically shifts in one direction. Hello Cark, thank you f...

Hallo zusammen! Wir hatten eine wunderschöne Nacht mit Nachthimmelsleuchten in Frankreich, beobachtet von den nördlichen Jura-Bergen aus in Richtung Nord-nord-west, bevor Staub von den südlichen Waldbränden mit dem Sturm aufstieg: https://forums.infoclimat.fr/uploads/monthly_2026_07/(700).jpg.38c170...

Marcel, Nicolas, Eure pyramidalen sind keine "einfachen" Halos... Salut, Elmar Hallo Elmar, ich hatte mich in dem Fall nach dem visuellen gerichtet und da war nur der 22°-Ring schwach erkennbar, auch wenn ich den 9°-Ring mit Hilfe einer Sonnenbrille ebenfalls extrem schwach erkennen konnt...

Hallo Marcel, wirklich wunderschöne Halos. Im Jura (Ostzentralfrankreich) hatten wir sie in den letzten Tagen auch, besonders am Dienstag, dem 7., allerdings abwechselnd mit oder sogar gleichzeitig mit den eher traditionellen Halos. Auch am darauffolgenden Morgen sahen wir sie, allerdings nur Halos ...

[Übersetzt aus dem Französischen mithilfe eines Online-Tools, um meine Nachrichten nicht auf Englisch verfassen zu müssen und sie vielleicht verständlicher zu machen] Guten Abend zusammen, wir konnten in der Ebene einige Polarlichter aus dem nördlichen Jura beobachten [47°N]. Die Aktivität erreichte...

Unless there is another light effect not along ecliptic line, linked to zodiacal light.
Below is a simulation using Stellarium, using the spot coordinates approximatively.

Ich würde ja das Zodiakallicht vermuten. Guck mal hier: https://de.wikipedia.org/wiki/Zodiakallicht I think this could not be zodiacal light, because at those latitudes, and at this time of the year at the morning, the angle between horizon and ecliptic line (where the zodiacal light extends its sh...

Hello there Marcel, nice to see the milky way so clearly indeed. Do you have also this light on other pictures you might have taken with a similar point of view that night or is it just at this time. - If the first, this might be a distant activity area (zone of industrial activity) in the next big ...

Hello there, auroras are now visible from France, with unaided eyes, despite the Moon.

Hallo zusammen... Das Video ist fertig. Siehe unten... @Jörg... Du vermutest GBRs...? Ich auch... Habe ich im Video versucht einzufangen. Auf den Bildern ist es vielleicht besser zu erkennen... Die lade ich gleich auch noch hoch... z4JmY-DQ6Bw GBRs...??? 03:00 UTC (der mit Pfeil - die unteren beide...

Hello there from France. thank you Marcel for these nice pictures of Airglow. We got also a nice display, recovering almost all the sky during that night, especially between 21:00 and 03:00 UTC Here is a video of the time-lapse from this night, with a configuration able to enhance the effect of the ...

Hello there, this "rocket" has been seen from Belgium as well (see Spaceweather gallery pictures ( 1 )). I do took this with my camera from my home last night (EOS 6D, 8mm fisheye lens, 20'', ISO1600) and it was a first time since 2009. Here is one of the picture I took, showing two parts ...

Hello there Karl, if you work directly with raw files , here is something that can help. The BR method (and the opposite one, B-R method) can be used with a plugin of GIMP, named UFRaw (and can be batch automated). You can find UFRaw here and it is a stand alone program, that can then be used withou...

Hello there Carl, thank you for those images and congratulations on the catch. This is interesting to me, since I tried to catch those sprites during this same night, but from south of them (I am located at 47,05°N & 5,5°E) Is the time 2:20 corresponding to the sprites you are showing there ? Un...

Hallo zusammen, hier nun ein Zeitraffer von 23:55 bis 01:27 MESZ mit den kürzesten Belichtungszeiten, mit denen ich während des Höhepunkts aufgezeichnet habe: https://www.carl-herzog.de/wetter/astro/images/2024-05-26-Polarlichter.mp4 Brennweite: 14mm (bei Vollformat) Weißabgleich: 4700 K Belichtung...

Hello there, those are nice indeed. As I was more south, I saw those RAGDA on my northern horizon, and coing close to 45° elevation some times. Here is a time lapse of the event, where you will see those RAGDA too, between 0'54'' and 1'28''. This is corresponding to real time between 00h15 and 01h30...
