IASC Logo

The International Astronomical Search Collaboration (IASC) is a citizen science program that provides high-quality astronomical data to citizen scientists around the world. These citizen scientists are able to make original astronomical discoveries and participate in hands-on astronomy. This service is provided at no cost!

Asteroid Search Campaigns are the primary focus of IASC. A "campaign" is a month-long event in which teams search for asteroids. If you are new and would like more information on the asteroid search campaigns, please use the Register link.

IASC announcements

The Allameh Tabatabai Asteroid Search Campaign, All Bangladesh Asteroid Search Campaign, Canary Islands Asteroid Search Campaign, All Nepal Asteroid Search Campaign, All Serbia Asteroid Search Campaign, All Turkey Asteroid Search Campaign, International Asteroid Search Campaign, Spaceport India Asteroid Search Campaign, NUCLIO Asteroid Search Campaign, MARSG India Asteroid Search Campaign, Kanoon Parvaresh Fekri Iran Asteroid Search Campaign, Hands-On Universe India Asteroid Search Campaign, Orbit '21 Asteroid Search Campaign, SEDS India Asteroid Search Campaign, SEDS Sri Lanka Asteroid Search Campaign, and UDistrital Asteroid Search Campaign are now underway. Happy Hunting!

Current Teams: It is important that you understand how to use Astrometrica, identify true and false signatures (i.e., not all moving things are asteroids), and prepare a clean and accurate MPC report. Remember, the Quick Start Guide can help you with all of these goals. If you can do these things, your citizen science group will be successful in discovering new Main Belt asteroids and making important near-Earth object observations.
