Location ISON-NM Observatory (H15) Coordinates: 32° 54′ 11.79″ N 105° 31′ 42.40″ W 2217 above sea level Asteroids, Comets, Meteors 2012, Niigata, Japan NMSkies astrohosting
Location Why NMSkies? Astroclimate - Many clear nights ( per year) - Dark skies (SQM ~ 22.1 mag/arcsec²) First light only in 5 month - Ready infrastructure (fast Internet) - Experienced support for remote observations Asteroids, Comets, Meteors 2012, Niigata, Japan
Telescope Asteroids, Comets, Meteors 2012, Niigata, Japan Centurion-18 Aperture – 455 mm Focus lenght – 1270 mm Focal ratio – f/2.8 CCD – FLI ML FOV – 100’x100’ Image scale – 1.95”/pix No filter wheel
Main tasks on ISON-NM 1. Survey for a new Solar System objects, include near-Earth objects 2. Follow-up observations of NEA and comets 3. NEAs photometry 4. Optical transients observation, include working with VOEvent 4.1 Gamma-ray bursts 4.2 Supernovae 4.3 Novae 4.4 Cataclysmic variables stars and other transients 5. Supernovae survey* 6. Patrol of cataclysmic variables stars* 7. Photometry of variable stars on survey's images* * - as by-product, this plans for the near future Asteroids, Comets, Meteors 2012, Niigata, Japan
