You observe a nova in the Galaxy. Ten years after the eruption you take a spectrum and detect a nova shell expanding at a rate of 1000 km s-1. If the nova has a stellar parallax of 0.0019 arcseconds, what is the distance to the nova? And what angular size (in arcseconds) do you expect for the nova shell? You observe a nova in the Galaxy.
