Abstract
In this work we propose the Amor-type asteroid 2009 WN25 as the likely progenitor of the November i-Draconids (NID, IAU#392), a recently detected weak annual meteoroid stream. We first describe our recovery and follow-up effort to obtain timely ground based astrometry with large aperture telescopes, and ensure that 2009 WN25 would not become lost. We then discuss the possible parent-stream association, using its updated orbit to model the ejection of dust particles from the surface of the parent body and match the observed properties of the stream.
