Bright white light, heading from northwest to southeast. Swerving flight path

At 5:46 AM I saw a bright white light traveling northwest to southeast while in my front yard, walking my dog. It did not have blinking lights, just bright white. The sky was still dark as the sun had not yet risen. Other stars, such as Orion's belt, were still visible. This light was as bright as the brightest star in the sky. The flight path originally looked straight, but I soon noticed it swerving, like a car in a 3 lane highway swerving between lanes. I have seen this at least 2 other times now, all exhibiting the same characteristics. It appeared very far away, no details about the shape could be seen, only that it was a bright light.
