Query: First results from multi-wavelength observations during the 2001
  outburst of WZ Sge   WZ Sge has shown superoutbursts in 1913, 1946 and 1978. On 2001 July 23 a new
outburst was announced, about 10 years `too early'. Target of opportunity
satellite observations with Chandra, FUSE, HST and RXTE were performed
throughout the outburst. From the ground WZ Sge was monitored by numerous
professional and amateur astronomers, in the optical, IR and radio. We give an
account of the first exciting results from these multi-wavelength observations.
