    I folks. I marked this a 'something weird'.
    Can someone explain how this pattern is generated?

    Interesting .. muon detector is light up like christmas tree, but there is not a single track visible

    was this a sim? only joking 😉 . good eyes i'd be interested in follow up.

    Go home ATLAS, you're drunk! 😄
    It was no sim actually 😉

    Good one! This is a fun event. What has happened is that a very energetic cosmic ray (muon) has showered in the atmosphere or rock above ATLAS creating hundreds of lower-energy muons traveling in the same direction at the same time. You've found a particle from outer-space (probably a supernova!), whose energy is greater than we can create at the LHC!
    I've attached a zoomed-out slice view, where I've also drawn the short muon "segments" found. (They usually don't make full tracks since they don't line up with the proton collision point.)

    Heyyy! Is this one of our first really cool finds? 😃

    Thanks for the explanation Andy!
    Wow, that bugger must have packed a punch when the detectors light up like that! I just read that those muons can travel through several kilometers of solid rock without problem and aren't all that uncommon. I wonder how often they are detected by (or interfere with experiments) at ATLAS. Doing this is so much fun 😃

    I feel a #dailyzoo coming up ! 😄

    PS : If you see something really cool, you can always mention it for the "Daily Zoo : something awesome from the Zooniverse every day" by using the #dailyzoo 😄
