Seeing multiple round yellowish/whiteish colored orbs/ufo's in the night sky almost every night in Fort Smith, ArkansasI am a seasoned photographer and for the past 8 months or so, I've been going outside into my backyard almost every night. I've been seeing some incredibly odd and wierd activity going on in the night sky since this past April of 2012. The main things I have been seeing are random stationary flashes of light in the night sky and white-colored lighted and sometimes orange-colored lighted round orbs/ufo's. The flashes of light seem to occur at random points in the sky and at random times. As for the white rounded lights and orange colored lights (orbs).. from the 6 to 7 months I've been watching/witnessing them, I've come to the theory that they are reacting/investigating commercial/civilian aircraft at night. My theory is that they are attracted to the strobe/beacon lights that aircraft must use during night time flights.. because whenever there is high air-traffic over the top of my house, that's when I tend to see them the most. The other thing that lea! ds me to believe that they're investigating and or are attracted to the lights from commercial/civilian/military aircraft is the fact that 90% of the time, when I see an airplane/helicopter approaching to fly over or close to flying over the top of my house.. 90% of the time I'll see one of these white-lighted orbs and the orb will suddenly appear (like someone turned on a light bulb from the switch) and will either intersect the paths of the airplanes or will follow the exact same flight path that the airplane/helicopter just flew.Also, sometimes these white colored orbs will be very dim.. but sometimes will slowly start to get really bright (like someone using a dimmer switch on a light bulb to slowly turn up or down the brightness level of the bulb) and sometimes they'll stay really bright for a long time and then they'll start to slowly fade/dim back down to their original brightness level.. or sometimes they'll even dim all the way out to where you can't see them at all. Almost like someone turned off the light switch, per say. That's the best I know how to explain it.I have quite a few of these things on video. I actually got the best video footage that I've ever gotten over the past 7 to 8 months.. just last night! I got video of a civilian airplane and one of these orbs passing each other. I also have video of these things showing how they go from almost invisible to incredibly bright and then dimming back down to either barely visibly or completely turned off.These objects appear to definitely be round in shape and when I watch some of the videos I capture of these things, I can actually see colors that airplanes don't use and the colors almost seem to morph into each other before each color changes from one color to another color.The best thing to do, in my opinion.. would be for me to send one of my videos to you, so that you can see exactly what I am seeing.Now, of course, there are nights where I won't see any of these things.. which is generally the same nights where there is very little to no air traffic within the vicinity of my house, which is yet another reason why I think these things are attracted to the lights from airplanes/helicopters.
