The Catalina Sky Survey:NEO Follow-up

Eric J. Christensen + CSS Team

LSST All Hands Meeting : 14 August 2012

css overview
CSS Overview
  • Funded by NASA’s NEOO program
  • 100% dedicated to NEO survey + follow-up
  • Assets: 3 survey telescopes + 1 follow up telescope
  • Cadence: 4 x 30 s images, deltaT ~10 min.
  • Filters: none
  • NEO candidates are pipeline-generated, human-validated in near-real time
iau minor planet center
IAU Minor Planet Center
  • Accepts and publishes astrometry of minor planets (“broker”, “subscriber” + “publisher”)
  • Calculates and publishes orbits of minor planets and comets
  • Provides tools and services for observers (NEOCP + Blog, MPCES, MPChecker)
lifecycle of a neo discovery
Lifecycle of a NEO discovery
  • Initial detection of NEO candidate
  • Astrometry reported to Minor Planet Center

  • Public posting on NEO Confirmation Page
  • Follow-up: confirmation and orbit refinement
  • Designation+ publication (MPECs)
  • Additional follow-up for orbit refinement
stages of follow up
Stages of Follow-up
  • Astrometric follow-up is useful at different times
  • Same-night: reality check + orbit refinement
  • Subsequent night(s): leading to “discovery”
  • Post-discovery:
    • Same + subsequent apparitions (recovery)
    • Refines orbit, prevents NEOs from becoming lost
css follow up now
CSS Follow-up : now
  • Same-night follow-up often conducted on survey telescope(s)
  • NEO candidates posted <15 min after reporting
  • Bright objects (< V~20) usually followed by other observing stations, often amateurs
  • Faint object follow-up conducted on our 1.5-m, or by others on 1 - 2-m class telescopes
css follow up soon
CSS Follow-up : soon
  • 1-m telescope under commissioning
  • 30 arcmin circular FOV, BVRI filters
  • Robotically operated, queue scheduled – programmed during day by human
  • Will accept, prioritize, and execute requests, return data to requestor
css follow up soon1
CSS Follow-up : soon
  • Initial stages of collaboration with Las Cumbres Observatory Global Telescope Network
  • Geographic distribution of LCOGT is ideal for on-call NEO follow-up
    • Access to near-Sun regions 3-4x per day
    • 24-hour monitoring of incoming impactors
