 J75 La Sagra Sky Survey

 

The current instrumentation used by LSSS to scan the sky consists of three 0.45-m f/2.8 telescopes. Follow-up of potentially interesting objects is done with a dedicated tracking telescope. The entire data acquisition and data reduction is done remotely via the Internet, by LSSS team members in Spain, Croatia and Hong Kong. For security and safety reasons one operator is permanently present at OLS. He is also supporting the remote observers and doing regular maintenance work. Since the August 2008 dark run LSSS is officially classified as a survey by the MPC.

 

To this date (Oct. 2011) LSSS has been credited with 5.855 asteroid discoveries, of which 49 are NEOs. Some of these objects are classified as unusual (Near-Earth Objects, Centaurs, Jupiter Trojans, Mars Trojans, Hungarias etc.). The most productive month in terms of discoveries has been August 2008 with 584 discoveries. Furthermore four comets were discovered until now.

 

 

 

LSSS discovery statistics

 

The plot on the left shows the evolution of LSSS asteroid discoveries since August 2006. The first two years were devoted mainly to test different equipment and to evaluate its usefulness for asteroid hunting. The number of discoveries virtually exploded in the summer of 2008 when the current instrumentation became operational. The plot on the right shows the distribution of semimajor axis versus inclination values for all LSSS discoveries with known orbits.
