Query: Observations of Near-Earth Optical Transients with the Lomonosov Space
  Observatory   The results of observations with the MASTER-SHOK robotic wide-field optical
cameras onboard the Lomonosov Space Observatory carried out in 2016 are
presented. In all, the automated transient detection system transmitted 22 181
images of moving objects with signal-to-noise ratios greater than 5 to the
Earth. Approximately 84% of these images are identified with well-known
artificial Earth satellites (including repeated images of the same satellite)
and fragments of such satellites (space debris), according to databases of
known satellites. The remaining 16% of the images are relate to uncatalogued
objects. This first experience in optical space-based monitoring of near-Earth
space demonstrates the high efficiency and great potential of using
large-aperture cameras in space, based on the software and technology of the
MASTER robotic optical complexes (the Mobile Astronomical System of
TElescope-Robots (MASTER) global network of robotic telescopes of Lomonosov
Moscow State University).
