(215188) 2000 NM (2000 NM) Apollo NEO +1km asteroid photographed on the first night of the August talcos. The asteroid was discovered by American amateur astronomer Leonard L. Amburgey Scott Observatory (823 – Fitchburg) on July 2, 2000. School teacher Leonard Amburgey has found a total of 2 asteroids in his backyard observatory in the town of Fitchburg in northern Worcester County, Massachusetts. Source Wikipedia . The entire estimate for the asteroid is 2.9 km and the rotation speed is 9.24 km. Spectral class Spec_B=>Sr . When photographed, the asteroid was at a distance of 0.2875au and at its closest on June 23, 2022 at 0.25327au. At the time of writing this report on September 2, 2022, we have just received the observatory code M31 for the Ursa observation center. The sightings of this asteroid belong to the first set of sightings reported by the MPC, although the 27-28.8 days first. Found at . Amateur observatories have photographed this object a lot, as it appears from the previous source.
