M.P.E.C. 2012-L30 issued on 2012, June 12 announces the discovery of a new Near-Earth object (discovery magnitude 15.1) by R. H. McNaught in the course of the Siding Spring Survey on CCD images taken with the 0.5-m Uppsala Schmidt. This new asteroid has been designated 2012 LZ1.2012 LZ1 is a large Near-Earth Object (NEO) approximately 300-700 metres in size (H=19.7) and it has been classified as a PHA (Potentially Hazardous Asteroid). PHA are asteroids larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time. 2012 LZ1 will be at its closest approach with Earth at ~14 lunar-distances (0.036 AU) on June 14, 23:10 UT. We have been able to follow-up this object from the Haleakala-Faulkes Telescope North on 2012, June 13.5, through a 2.0-m f/10.0 Ritchey-Chretien + CCD.At the moment of our images from FTN, "2012 LZ1" was moving at about ~33.64 "/min and its magnitude was ~14.2. At the moment of its close approach it will be bright as magnitude ~13.9 and moving at ~38.80 "/min. Anyway, for the following days, it will be ...
