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.

New Interstellar Visitor to the Solar System: Comet 2I/(Borisov)

At the time of discovery, the object seemed to be a typical comet-it was discovered when observing near the sun in the morning sky and sported a small tail. Gennady dutifully re-observed the object the following night, and by this point it was posted on the Minor Planet Center's Possible Comet Confirmation Page such that other observers worldwide could observe the object.
