I was walking my dog and the night sky was overcast. It was clear there was lightning storm in the distance but you could not see one single star in the sky. I walk my dog every night an always observe the night sky looking for irregularities but usually just see planes and star patterns. I looked up to my right which was a south east direction and see what appeared to be a glowing reddish orange orb with a red aura around it. At first I thought it was a plane based on the direction it was coming from and there being an airport in that direction. However it did not blink or have any additional lights like the planes I see every day do. It maintained a steady speed like an aircraft in a straight line towards the west heading towards clearwater beach area. I then thought it could be a lantern or something similar but it was moving too fast and did not ascend at all. I stood there in awe and a neighbor pulling up in his car saw me staring and got out of his car and saw what I was looking at. We proceeded to watch the object for about another 10-15 seconds until it vanished. I did not know what to think because I like to consider myself a believer and that we are not alone but have never experienced anything like that before. I was so frustrated because I always have my cell phone on me when I walk my dog but I did not bring it with me to record any video or take photos.
