At 02:30UT (11:30 local chilean time), a couple of the astronomers on duty at the ALMA control room spotted this strange and fuzzy object outside. It was fuzzy just like a comet. Brightness was about that of the Large Magellanic cloud or brighter. It got fainter over the course of 1 hour. Position changed rapidly as well as brightness going from easily naked eye visible to just visible in a 30s SLR camera exposure.
