1858 Lobachevsk (or Lobachevskij) (1972 QL) is a Main-belt asteroid that was discovered August 18, 1972, by L. V. Zhuravleva. The asteroid was named in honor of mathematician Nikolai Lobachevsky.[1] It is 17 km in diameter. [2]
In a May 2002 photographic survey, United States astronomers found the rotation period of this particular to be 7.00 plus or minus 0.01 h, with an amplitude of 0.6 mag.[3] Its absolute magnitude was determined to be 11.5.[1]
The asteroid covered a 10.4 mag star -- a phenomenon known as occultation -- in the constellation Sagittarius in June 2007. It was predicted that the event could be seen in the northeastern United States and southeast Canada. The combined light magnitude of the bodies would drop momentarily -- for a maximum of 2.2 seconds.[2]
Zhuravleva is ranked 43 in Harvard's ranking of those who discovered minor planets. She discovered 200 such bodies, 13 of which were co-discoveries, between 1972 and 1992.[4]
