Abstract
We present the absolute proper motion of Nova Velorum 1999 = V382 Vel based on photographic plate material from the Yale/San Juan Southern Proper Moti on program. The absolute motion, on the system of the International Celesti al Reference System, is mu(alpha), cos delta = -11.5 +/- 2.3 and mu(delta) = -1.7 +/- 1.9 mas yr(-1). This proper-motion measure adds to the growing n umber of such measures for novae and will eventually allow the secular para llax for this class of objects to be determined. We also report the preoutburst B and V photometry of V382 Vel. In its quies cent state, the nova has mean values of V = 16.56 and B-V = 0.14. A brighte ning by 0.5 mag is noted in 1970 (JD 2,440,705.542).
