    Hello.

    Auroras could be added to future version. You can see auroras in:

      I tried to load several images one after the other with just a bit of "ondulation" effect but the result was not good enough...

      As for the copyright, I only wrote it in the readme.txt file. So I'm gonna add it in the script file as you suggest.

      Tanks again Rob for your constructive feedback.

      Great idea, looks fantastic! Here are two more aurora images you can play with.

      I've never seen the aurora myself, even though I spent some time in finland, but fading consecutive images in and out as Rob says, could that work?

        Try this as a script with the image from the post above.

        Aurora simulation test

        image action load filename aurora2.png name a1 coordinate_system horizontal
        image action load filename aurora2.png name a2 coordinate_system horizontal
        image action load filename aurora2.png name a3 coordinate_system horizontal
        image action load filename aurora2.png name a4 coordinate_system horizontal

        image name a1 altitude 30 azimuth 0 scale 50
        image name a2 altitude 30 azimuth 10 scale 60
        image name a3 altitude 20 azimuth -10 scale 50
        image name a4 altitude 30 azimuth 25 scale 60

        image name a1 alpha .1 duration 10
        image name a2 alpha .1 duration 10
        image name a3 alpha .2 duration 10
        image name a4 alpha .2 duration 10

        wait duration 10

        image name a1 altitude 30 azimuth 20 scale 60 alpha .1 duration 30
        image name a2 altitude 10 azimuth -30 scale 40 alpha .1 duration 30
        image name a3 altitude 20 azimuth 30 scale 40 alpha .2 duration 30
        image name a4 altitude 10 azimuth -40 scale 70 alpha .2 duration 30

        wait duration 35

      Great Rob ! That's just the effect I was looking for, and your script makes it perfect !

      I've just added some time, location and zoom setup not to have to search for the aurora...

      To run a script :

      Unzip / copy all the files in the Stellarium/data/scripts directory

      • open Stellarium :
      • press M
      • use the arrows keys and find the script menu
      • choose the script xxxxxxx.sts
      • press [Enter]
      • press M
      • Enjoy

      Just a little try :

      (Download and read the readme.txt file)

      http://vincent.gian.club.fr/stellarium/aurora.zip

      What about adding video feature to Stellarium to make these little scripts still more realistic...

        That's an interesting application of scripting.

        If you slowly fade between a few different images you can simulate auroral motion.

        I would also suggest putting your copyright in the acutal script header comment so it stays with the script.

      How do to create and run a script?
