Bright white/red changing light moving calmly across sky, possible round/oval shape to itI was standing outside at about 11:00 in the morning. I live in Claremont, Ca, a suburb of Los Angeles, a city that lies against mountains, on the other side of those mountains is desert. I believe we are stationed in a path on the way to a military base, as I have often seen military helicopters flying over, and we are stationed on some sort of air travel path as many vehicles fly overhead often. I noticed that it was a very clear day. I was standing looking westward, which I consider to be Los Angeles, and I noticed a bright white light in the sky. Which is unusual, as you don’t usually notice lights in the sky during the day. It was metallic and white looking and I thought it moved unusually. It was extremely bright and from a distance just looked like a spot/metal. It was very far in the distance and seemed very high, so I thought if it moved closer I could tell if it was a plane or a helicopter. As it came nearer and closer, I noticed there was a red tint to it as well. I thought it maybe a blimp. As it moved towards me, along this northeast path, along the mountains, and the same direction as the weather clouds today, it became brighter. The white/diamond light became stronger and it also flashed red. The lights were unusual, more high-tech than most planes or other flying objects. The shape was cigarish. I became slightly frightened as the light was very bright. It continued moving on its path over my home and along the northeast latitude along the mountains, and continued until it was out of sight. The entire time was approximately five to seven minutes. I did not have the time to go inside and get binoculars in order to get a closer view. I have seen an unusual light at night one other time, but this was by far the rarest and most unusual sighting. The movement was also strange, as it moved in a very fluid and smooth/high tech manner. As far as I could tell, it was not emitting sound that I could hear. I have heard other auditory flying vehicles in the air ! since I sighted it, but I cannot see what craft is emitting that sound.I tried to do a quick research as to weather this could have been a weather balloon, but my immediate response that I’ve found seems to be that weather balloons do not emit light. My background is mostly that I have an interest in many things, but I do have a slight knowledge of ufo subject matter, and I do sometimes listen to coast to coast, and sometimes read on the internet. I noticed when I went on your website and looked at other sightings that someone in Rancho Cucamonga has written to you, which I find interesting as that is a neighboring city, although we saw two different colors of lights, we did see things in a similar time area. I will try in the coming days to keep an eye out, and will possibly try to go outside tomorrow at the same time. I have to say, today’s visibility is exceptional, and visibility here changes day to day and hour to hour. Yesterday it was overcast. Also, smog, clouds, being against mountains, etc. influences. Not sure what I saw but it was interesting.
