Introduction

2025 FA22 will make a close approach on September 18, 2025, UTC at a distance of 2 lunar distances. This close approach prsents a perfect opportunity for an IAWN campaign.

The goal of the 2025 FA22 campaign is to exercise our capability to collect position and physical characterization data on this former virtual impactor. For the purpose of the exercise, we will treat this object as a current virtual impactor with a Torino Scale >= 1 with a hypothetical impact on September 19, 2089.

The campaign will start with the optical 'recovery' around September 17, 2025, when the object is between 40-60 deg. Solar elongation. The orbital improvement from recovery data is meant to facilitate rapid characterization of the target.
