RemarksSaw a bright yellow/orange elongated cluster of fragments of various sizes some ahead some trailing behind. Was clearly a re entry of something as it was moving at satellite velocity, ie very slowly. Continued to fragment with some fragments disappearing as it continued across the entire sky from south to north. One persistent fragment appeared to survive the burn as it continued to be visible almost to the northern horizon. Spectacular.
