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 Motion program. The absolute motion, on the system of the International Celestial Reference System, is μαcos δ = -11.5 ± 2.3 and μδ = -1.7 ± 1.9 mas yr−1. This proper‐motion measure adds to the growing number of such measures for novae and will eventually allow the secular parallax for this class of objects to be determined.We also report the preoutburst B and V photometry of V382 Vel. In its quiescent state, the nova has mean values of V = 16.56 and B−V = 0.14. A brightening by 0.5 mag is noted in 1970 (JD 2,440,705.542).
