V705 Cassiopeiae

V705 Cas, or Nova Cas 1993, was a bright northern hemisphere nova that reached fifth magnitude.  It belongs to the class of novae with dust dips starting shortly after maximum.  The nova fades rapidly by as much as ten magnitudes before returning several magnitudes fainter than before.  These novae also take a very long time to return to quiescence, with the duration of the fade measured in decades.  The nova event for DQ Herculis (Nova Her 1934) is perhaps the most famous of these, although DQ Her itself has become even more interesting as the prototype of the DQ Herculis stars.

V705 Cas currently has a V magnitude between 16 and 17.  It fell below V=16.0 around the turn of the millenium, seven years after outburst.
