MPEC 2012-N19, issued on 2012 July 14, reports the discovery by J75 OAM Observatory, La Sagra of the unusual minor planet 2012 NJ with the 0.45-m f/2.8 reflector + CCD. According to the latest orbital solution available, this object moves along a comet-like orbit with an Inclination of 85.03 deg, Eccentricity = 0.90, Perihelion distance = 1.29 AU and Period = 48.57 years.We performed some follow-up measurements of this object, while it was still on the neocp, remotely from the H06 ITelescope network (near Mayhill, NM) on 2012, Jul. 14.3, through a 0.51-m f/6.9 reflector + CCD. No cometary features are visible in our images, the object has the same aspect of the nearby field stars of similar brightness.Our confirmation image, stack of 10x10-second exposures (click on it for a bigger version):Below you can see an animation showing the movement of 2012 NJ (each frame is 10-second exposure).
