1. My fiancé and I were on our balcony in downtown Los Angeles.2. Ever since we moved to our current location a year ago I have seen a number of strange things in the sky. First they were just bright star like circles moving all over the place to just really fast across the sky. The recent one that I am reporting was at first just a star/ circle I jest moving very fast. I pointed it out to my fiancé and he used his star guid app which told him it could just be expected space debris flying by but then sure enough another insanely big thing came into view. There had to be over 20 or more circle/ star like bright flying things that were attempting to fly in a perfect boomerang/ v formation. It was very big and hard to miss. It flew across our vantage point if the sky until going out of view behind a building. After that another single fast moving bright circle/ star like thing sped across the same area in the sky. Then another fleet flew by in the same type of formation except this time it looked like a singular one was joining the group why fly across the sky sky we can see from our balcony to go out of sight behind the same building. 3. We thought nothing other than amazement. It looked like something out of Star Wars. We did not try to get footage of the objects because by the time we could quantify what we were seeing the crafts were no longer in view. 4. The objects were circular, looking like blue/white/ bright stars flying fast in formation going from east to north east. 5. Ever since moving to our current spot I have seen countless odd things in the sky but only from our balcony. Most of the time I feel very oddly happy or not much at all. This time what we saw made me feel a tad worried. Seeing two big fleets fly buy just did not feel innocent in nature to me which is why I thought I would report.6. From our balcony we can only view a very small specific part of the sky so when we have seen Ufos they either just disappear right in front of our eyes or go out of frame, meaning we lose sight of them because they fly past where we can see behind a building. The fleets we saw last night did just that. They flew across the part of the sky we can see until we lost visual as they went behind a building.
