Satellite-like light stops above North Hollywood/Hollywood Hills and fades in and out irregularlyI had just gotten into bed, around 2:40am, and was looking out my window of my room on the 9th floor of my building. I usually sleep with the curtains closed, but this time I left one side of the curtains pulled open. (From my window I look north onto the south side of the Hollywood Hills.) On this night, which had been clear to partly cloudy, it caught my attention that the clouds appeared to have a warm hue and I found it odd that I could make out the shapes at such a late hour. I figured that the clouds were lower than usual and thus reflected more of the city lights. This was the reason why I was staring out my window for about five minutes while in bed rather than trying to fall asleep. Around 2:45am I saw what appeared to be a satellite pass into my line of sight at about 20 degrees above the horizon traveling from west to east. About 1 second after appearing within my vision, it stopped abruptly, roughly above the North Hollywood area. This was not a helicopter. It was not blinking red and blue lights. I initially thought it was a satellite but its intensity varied greatly to that of a very faint star and it mostly emitted a bluish white light. For the next 2 or 3 minutes the light would flicker/fade in and out irregularly. At times, I could not tell if the light was moving while it faded in and out or if there were one or two OTHER lights on either side of it also behaving in a similar manner. The sky quickly became overcast around this time as clouds blew in from east to west. When these clouds finally passed, I woke up my roommate, but only to point out what where obviously stars. The strange light was nowhere to be seen.While I was looking at this object move erratically, I thought that perhaps my adrenaline and excitement were causing my eyes to shake. I would repeatedly look away from the object to focus on the lights of buildings, street lights, and radio masts, scattered along the Hollywood Hills. These appeared quite normal and steady.Of course, as I got back in bed after about 5 more minutes of scanning the sky, I continued to look out my window. As I did so, I witnessed a cloud/ cloud-like object form from a small silver orb into a curved-rhombus shape and dissipate right before my eyes all within 1 minute. I have never seen a cloud behave this way and my heart was beating incredibly hard at this point and I began to feel very disturbed. I am hoping that other witnesses can confirm what I saw.
