Asteroids, NEOs & Comets
Asteroid results
We have been doing active follow-up of possible Near-Earth Objects and comets candidates. We have also confirmed and discovered comet outbursts events. We have developed Astreaks, a robust automated pipeline for the astrometry of non-sidereal images where each star appears as a line. You can find more details for the same on the Astreaks page.
Here, we list our refereed publications, ATELs, and MPECs.
