Of all the articles on this object I thought that the article in nature was the best one. Some may find it interesting that the object was monitored by amateurs (professionals failed to do so due to poor weather) on its way in and lightcurve data was obtained and the results published in the Minor Planet Bulletin - A very fast spinner at 97 seconds.
