AAVSO observations of dwarf novae were used to select targets in a search by the International Ultraviolet Explorer (IUE) satellite for their white dwarf components.  Twelve of fourteen attempts caught the dwarf novae in quiescence.  Lyman alpha absorption such as seen in white dwarf stars was found in three of the six observed systems, two of which, RX And and TZ Per, are described here.
