Oval object with a white and blue florescent glow in Los Angeles, Northridge close to van nays airport

It was a big oval shape object with round lights around, it looked like it doesn’t have any weight, moving with little angle maybe 30 degrees to left for 30 second first then immediately to right again to left then to right all of the movement with angel, and with blue fluorescent light the round lights around had a yellow florescent color more like the ones they say it has sun color, for maybe 60 second and it was pretty big like big as the small airlines planes for travel, it was pretty clear not very far.
