V1647 Ori is a young eruptive variable star, illuminating a reflection nebula(McNeil's Nebula). It underwent an outburst in 2003 before fading back to itspre-outburst brightness in 2006. In 2008, V1647 Ori underwent a new outburst.The observed properties of the 2003-2006 event are different in severalrespects from both the EXor and FUor type outbursts, and suggest that this starmight represent a new class of eruptive young stars, younger and more deeplyembedded than EXors, and exhibiting variations on shorter time scales thanFUors. In outburst, the star lights up the otherwise invisible McNeil's nebular- a conical cloud likely accumulated from previous outbursts. We presentfollow-up photometric as well as optical and near-IR spectroscopy of the nebulaobtainted during the 2008-2009 outburst. We will also present results fromcontemporaneous X-ray observations. These multi-wavelength observations ofV1647 Ori, obtained at this key early stage of the outburst, provide a snapshotof the "lighting up" of the nebula, probe its evolution through the event, andenable comparison with the 2003-2006 outburst.
