   The last outbursts of UZ Boo were in 1994 and 1978. In 1994 it peaked
  around 11.5 before fading slowly over a few weeks according to AAVSO data.
  There is very little data on this star. Early analysis by Arto of his time 
  series data does not reveal superhumps at this time.
  
   Visual observers are asked to follow this star closely. CCD observers are
  asked to get as much time series data as possible, preferably with a V
  filter, followed by B. We need global coverage with as little gaps in the
  observations as possible. Please try to get long observing runs.
