Our Mission

IAWN was established (2013) as a result of the UN-endorsed recommendations for an international response to a potential NEO impact threat, 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.

Welcoming Northolt Branch Observatories to IAWN

(Jun 2019) IAWN would like to extend a warm welcome to Northolt Branch Observatories. Earlier this week they submitted a formal request and it has been accepted by the Steering Committee. Northolt Branch operates three facilities with observatory codes Z80, Z48, and Z37 that specialize in asteroid and comet astrometry. The location of the observatories ...

1999 KW4 Observing Campaign

(May 2019) The Binary near-Earth asteroid (66391) 1999 KW4 will fly by the Earth at a distance of about 5 million km (about 13 times the distance from the Earth to the Moon) on May 25, 2019. IAWN is organizing a campaign to observe 1999 KW4 during its close-approach. While 1999 KW4 is relatively well-characterized binary system, this asteroid serves as a reasonable analog to prepare for other binary NEAs, and the campaign will see what resources might be brought to bear on a relatively short notice. The campaign will also help fine-tune plans to observe/support the Double Asteroid Redirect Test (DART) mission impact into the Didymos system.
