Glowing orb which suddenly vanished.

I looked out of my glass deck door and saw a glowing light which looked odd and not like an airplane. It looked orange and white. I ran to my room to grab my phone and caught it on video for a few and then it disappeared. I also saw aircraft activity near it but this did not resemble an airplane or helicopter. The encounter laster about a minute or so after I saw it but it could've been there longer. I also have been noticing other glowing strange lights lately plus extra airplane activity and saw another white round glowing light last week but it was moving slowly. My and my girlfriend both saw the one last week but the one tonight I saw alone. This one looked lower to the ground and closer. I also noticed my outside flood light which hasn't worked in 2 years flicker for about 2 hours a week ago which I found strange.
