I was standing outside at the location listed above as a bright blue light lit up the night sky causing me to see my own shadow on the ground. as i looked up into the sky, i observed a light blue orb ascending up into the sky at a high rate of speed. as it ascended, it turned into a larger bright white orb. the orb reached an altitude where it became a spherical haze dimming out of sight through heavy cloud cover above. i'm a big believer of ufo's and i'm convinced that we are not alone. this is not my first experience. i didn't feel in fear for my safety at all. i was completely cut off guard when this occurred. my reaction to this was i immediately knew it was a ufo or something out of this world. the speed of how fast it was able to travel up into the atmosphere was beyond anything we probably can create as humans. it took milli seconds to travel from approximately 500 ft above my head to miles up into the sky. if you were to blink, you would have missed it. all this occurred within 2-5 seconds, if that. i found a picture online that resembles what i saw on ifscience "what on earth was this mysterious light in the sky above the west coast last night?" as i was googling to see if anyone else had seen anything remotely close to what i observed tonight.
