is the object in question. TLE are notoriously poor near re-entry however as they have an extremely simplified model of drag. The actual behavior of the object depends on its aerodynamics, orientation and construction as well as the state of the upper atmosphere from hour to hour. In general there are no publicly available sensors to monitor LEO objects continuously, so "watching it's re-entry" will not be live. Various military organizations around the world have infrared sensors looking down on the earth for missile launches. While they will likely observe the re-entry live, we likely won't see those data until declassification decades from now, if ever.
As we get closer to the event, we might get a better idea of exactly when and where it will re-enter. If it is near populated areas we someone might set up cameras along the predicted final track, but getting all that set up on short notice for live streaming seems challenging. More likely we will dashcam and/or security cam video after the fact. Personally I am hoping if falls unseen over the ocean where no-one is nearby to risk getting klonked on the head with it.
