Almost identical to one I observed a couple of years ago. It too passed seemingly over my building so I would only have seen the end of its path ... about 1 second or 2 at most. I'm on the top floor of my building and can look almost directly up. I had just 10 seconds before spotted a minor meteor halfway down in the horizon (facing NNW) traveling in a different direction (west to east). I was already looking upward and spotted this brighter one right away as it passed over my location.
