At 2007 UTC he witnessed an unusually long and bright flash in Mare Nubium, an ancient lava-filled basin with a darker appearance than its surroundings.

We are hearing about this now because the scientists involved published their description of the event in the journal Monthly Notices of the Royal Astronomical Society.  By the way, video links are included below the fold.

The Spanish telescopes are part of the Moon Impacts Detection and Analysis System (MIDAS) system that monitors the lunar surface. This project is being undertaken by Prof. Jose Maria Madiedo, from the University of Huelva (UHU), and by Dr. Jose L. Ortiz, from the Institute of Astrophysics of Andalusia (IAA-CSIC) and continues a pioneering program that detected sporadic lunar impact flashes for the first time.
