A couple weeks ago (Oct 1), I reported:
Two blasts, called X-ray flashes, occurred on September 12 and 16. These were followed by a more powerful burst on September 24 that seems to be on the cusp between an X-ray flash and a full-fledged gamma-ray burst. NASA indicates that these markers may warn of an imminent supernova explosion.
The question is "Were any supernova events observed?" This could turn out to be an important tool, if the predictions come about.
