I found WZ Sagittae at mvis = 9.7 in the rising phase of the historical outburst on 2001 July 23. This article vividly reports the very exciting situation at the discovery.

WZ Sge is one of the most famous cataclysmic variables (CVs), and forms the WZ Sge sub-class with several other enigmatic SU UMa-type dwarf novae. The unusual characteristics of the WZ Sge stars are rare superoutbursts, large amplitudes, and no (or only few) normal outbursts. As to WZ Sge itself, the outburst cycle is over 10000 days in average. The outburst amplitude is 8 magnitude. Its magnitude is around 15th in quiescence.
