Abstract
We report astrometric parallaxes for three well-known dwarf novae obtained using the Fine Guidance Sensors on the Hubble Space Telescope (HST). We found a parallax for SS Aurigae of π = 5.00 ± 0.64 mas, for SS Cygni we found π = 6.02 ± 0.46 mas, and for U Geminorum we obtained π = 10.37 ± 0.50 mas. These represent the first true trigonometric parallaxes of any dwarf novae. We briefly compare these results with previous distance estimates. This program demonstrates that with a very modest amount of HST observing time, the Fine Guidance Sensors can deliver parallaxes with sub-milliarcsecond precision.
