At about 8pm on Thursday night , March 17, 2016 about 50 to 100 colorful ufo's flashing red and green and yellow flew silently toward the house about 400 feet up. Most stopped, took a vertical position and hovered, very closely to each other. Some flew toward the east. Some flew a bit, stopped and hoveted horizontally. They are still here 9 hours later. My family and I were mystified. I had seen strangely colored lights on the backyard up by the stars for the past 8 months. These seemed to ve the right color but much closer. We were more curious than afraid. With drones and such flying around we just weren't sure what to think. There were way too many and hung very closely together to be drones we later determined.
