| Description: | This very peculiar star was identified as a
nova in January, 2002 but has turned into a unique class of celestial
object. The ejected shell has shown significant change over the
intervening 11 months, relatively rare for stars, and has turned into a new
class of object. The nebula is thought to be a light echo illuminating
matter previously ejected during the star's evolution. Up is ESE.
The object is located very near GSC4822:39.
