Abstract

V838 Mon was a previously unknown variable star that was discovered in outburst early in 2002. It exhibited 3 peaks in its outburst and rapidly evolved to become an L supergiant. The early spectra showed s-process elements and later infrared spectra showed VO, AlO, and other molecules implying that the ejected material was oxygen rich. A light echo was discovered in late February 2002 and observations with the ACS on HST have provided spectacular images and a geometric measurement of the distance. We briefly describe a worldwide campaign to study this variable in outburst and return to quiescence.
