This video was captured by an ISS video watcher. The object, or shadow, is moving too fast to be a plane, so it is either space debris, a satellite in lower orbit than the ISS or the shadow of the ISS on the surface of the storm. Or, of course, it could be something of unknown origin. In any case, it’s a great catch by this observer!

Possible unknown, no way to evaluate further.
