[vsnet 21] Dwarf Nova Oscillations

["William F. Welsh" <wfw@astro.keele.ac.uk>]

Dear vsnet Observers,

   I have an upcoming observing run at La Palma on the 17-19th of February.
The purpose of the observing is to study the "dwarf nova oscillations"
(DNOs), which are small amplitude, periodic oscillations seen only when
dwarf nova are in outburst. (I can send more details if you are interested). 
In order for my project to be sucessful, there must be a dwarf nova 
in outburst while I am at the telescope.

   Can you help me determine the state of the following dwarf novae during my 
run? I am most interested in the following systems:
        SY Cnc
        CN Ori
        U  Gem
        KT Per
       (HT Cas)
       (Z  Cam)

Any help you can offer would be greatly appreciated.
With much thanks,
Bill Welsh
