Notes:

1. The very blue colour of this variable star at minimum indicates that
this is quite probably a dwarf nova. The minimum magnitude quoted in the
New Catalogue of Suspected Variable Stars, namely 16.0p, in incorrect as
determined by this current photometry.

2. This ROSAT candidate CV was seen in outburst in August 2000 
(Vanmunster 2000, vsnet-chat 5202).

3. Varies at minimum between about V=18.1 and V=18.8.
