Our Mission

IAWN was established (2013) to create an international group of organizations involved in detecting, tracking, and characterizing NEOs. The IAWN is tasked with developing a strategy using well-defined communication plans and protocols to assist Governments in the analysis of asteroid impact consequences and in the planning of mitigation responses.

Currently, IAWN includes members from Europe, Asia, South and North America.

Case Study of 2017 YZ1

On December 20, 2017, observer D. C. Fuls of the Catalina Sky Survey discovered a new Near-Earth Asteroid drifting southward in the constellation of Sextans. Over the next few days, the object was observed by other worldwide observing facilities such than an orbit could be calculated. The Minor Planet Center announced the object on M.P.E.C 2017-Y79 and designated the object 2017 Z1.

Catalina Sky Survey 60inch telescope

Upgraded CCD detector for Mount Lemmon Survey telescope

The most important capability upgrade in 2016 was the installation of a monolithic 10K × 10K CCD for The Catalina Sky Survey's Mount Lemmon (observatory code G96) 1.5m reflector. This new detector allowed for approximately 5 times the area coverage as the previous camera, and the results were impressive. G96 had more than a 100% increase in discoveries over the previous year. This increase is almost entirely responsible for the 20% increase in discoveries from the previous year.
