The 2009 Outburst of V630 Cassiopeiae

We present observations and analysis of the 2009 outburst of the unusual dwarf nova V630 Cas which is only the third recorded outburst of this star. The outburst lasted about 104 days, with the rise to maximum being slightly slower than the decline, which we interpret as an inside-out outburst. At is brightest it had V = 14.0, 2.3 magnitudes above the mean quiescence magnitude. The characteristics of the outburst are similar to several other long orbital period dwarf novae.
