Chevron shaped UFO San Marcos, CA

UFO sighting 9/7/21 at 10:41 pm. Over San Marcos, CA area. Moving in a westerly direction northwest of where I was located. My girlfriend and I were out on our balcony just enjoying the night air and looking at the stars and planets like we do from time to time. I noticed one that appeared to be brighter than usual. I mistook it for the star Arcturus if I remember correctly and tried to “prove it” to my girlfriend using the Star Chart app on my phone. She interrupted and told me it was moving. I also noticed it moving. There were no flashing lights and it was moving way to slow to be a plane. There was no noise that we could hear like with the planes that come into our area. I snapped a quick pic and we ran outside into the street to try and get a better look as the UFO was moving behind our neighboring building. By the time we got down to the street we could not see it anymore. After looking at the pic there wasn’t much to see until I zoomed in on the point! of light and it revealed more than I’d seen before in  any other pictures of the night sky I have taken. Ive since taken pictures of planes in the area with landing lights on and they look nothing like this picture.
