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...

And I forgot, during the big impulse that occurred around 00h30, they were multiple of those pillars, above multiple instances of green proton auroras, like in the attached file:

http://www.schule.suedtirol.it/rg-bk/oldhp/sar_steve.jpg Hello there I have the same pillars on my pictures, and it seems that they are appearing just after the green proton auroras laying below. This correspond (00:51:XX time code) to the 19th to 20th second of the first time-lapse I made ( here )...

Hello there. Congrats on those images ! We got a marvelous display from France too. Here is a first time lapse I made from my location (Jouhe, Jura, France), where we can see the SAR (looks like there is some like one inside a second one, before vanishing) and might be also GBR, in the second part o...

Hello there.
I have not found the information either.

By the way, the inventory done by Jaro Moilainen & Maria Gritsevichin 2022 do not mention how it is produced either.

Unless something has been done in last years.

Hello there Marcel, this is interesting display, with this mix of odd radii and conventional halos. What you caught between 9° and 18° halo is the 13° halo . We got similar display (halos types, sharpness) this past two days from eastern part of France and the 13° halo was there too. Greetings from ...

Hello there, This is a nice one indeed. I tried over the years to get the same arc from the Moon during Winter, and I might have got it too. Like the one you had, I did not get any circumscribed halo, nor other plate crystals related halos, but instead, some odd radii ones: 9° and 35°, along with th...

Very nice ones ! Congratulations!

We had, from Jura, Moon halos too those past nights, but not as sharp as those ones.

Nice ones, Marcel!

Hello there Carl, nice one on the Moon for this last night. I was on the roof too for the catching, but I forgot to turn the lense heater on, so manage to get nice droplets on the camera instead of halos. Almost 2 month without halos picturing here too, all the automatisms are not back yet. But as y...

Hello there Michael, indeed, with discussion on this matter on the french forums, we thought also that giving the fact that matter tends to follow magnetic lines, the shape seen from my location where not rectilinear as it appear to be, but curved towards the south, like you wrote also, showing the ...

Hello there Carl, indeed, there might be more to find in the pictures. Thank you for your hints. Here is a shared folder of what I managed to render so far, but I am not finished yet. For the blue spot, here is a explanation on what to look for when searching for it, if you don't already know this l...

Hello there, the shown images in this new of Spaceweather is a consequence of discussion with Emmanuel Baudoin (his images), on french forum Astrosurf , in parallel of this present topic on your forum. We try to draw the attention of Spaceweather in order to gather more images from different locatio...

Thank you for your answers. Indeed, for the odd radius halos, I can have with mixed pyramidal and non-pyramidal crystals too ( last 17th October gave me a nice view too ) For the 9° halo quesiton, for my part, I often get 9° halo alone among other non-pyramidal halos, but the shape of the 9° halo is...
