What is it ??
What's that long green bar ? I don't know how to link the picture to the discussion so I give its ID on Sky Server : 1237655349427437744
Is it a malfunction on the visual instruments ?

Hi Dr Debilnotnik and welcome to the Zoo
The green stripe is a satellite trail As the satellite catches the sunlight and because of its speed it only gets caught in one filter.
But just a question, did you get this image to classify ? Because we are now classifying single band filters only.
Happy hunting ! 😄
Thank you Elizabeth for your quick answer and your clear explanation 😃
Actually, this image wasn't to classify, I was just taking a look randomly on Sky Server and I found this strange bar. 😉
Have nice day !
I note that these satellite trails are in fact relatively quite common and appear on different colors.
For those who might be interested :
