Nova Puppis 2000 (V445 Pup) has been proposed as the first example of a helium nova. Recent optical spectroscopy of V445 Pup at V=19.91 mag obtained with IMACS on the 6.5-m Magellan telescope, shows that the spectrum consists of HeI, [OI], [OII] and [OIII] emission lines and no hydrogen is present. The spectroscopy shows an expanding nova shell with blue- and redshifted velocity components around +/- 850 km/s and +/- 1600 km/s. Images taken with Magellan under very good seeing conditions (FWHM ~ 0.6") shows V445 Pup to be extended (full width at zero intensity ~ 1.9") and elongated (position angle ~ 150deg). We have followed the secular evolution of V445 Pup since the decline from (optical) maximum, at near-infrared wavelengths (J, H and Ks) using the Infrared Survey Facility (IRSF) at the Sutherland site of the South African Astronomical Observatory. We find that V445 Pup is still covered by a dense dust shell more than three years after its outburst. ; Comment: 2 pages, 1 figure.
