A strange light in the sky just stationary

It's white light glowing brightly at about 35 degrees in the north sky. Just hovering.
I patrol every hour on the half hour for 12 hours and I know what the sky looks like because I can see what is out there each time I go out and this time this light showed up and I'm not sure what it is but it's never there and it's not moving I took a video of it but my camera is not focusing on it. Since it's cold I had to come back inside but I was out there for a good 15 minutes just watching. I was able to move to where a tree was between me and the object and I can see the light between the leaves and I stood still and I can tell that the object was barely moving I mean a millimeter or so at a time but it's definitely moving to my right the tree is not moving the wind's not moving and I'm completely stationary and I focused that light of that object perfectly in the tree branches like a site on a gun basically.
