dc.descriptionWe present CCD V and I band photometry and visual observations of V1663 Aquilae (Nova Aquilae 2005). This was a classical fast nova, probably of type Ba, observed for the first time on 2005 June 9. Maximum light occurred at HJD= 2453531.2 +/- 0.2, when the apparent V magnitude was 10.7 +/- 0.1 and the V-I colour index 3.1. Decline times were t2,V= 17d, t2,I= 18d, t3,V= 32d and t3,I= 35d. We derived a maximum absolute V magnitude of -7.8 +/- 0.2, colour excess E(B-V)= 2, extinction AV= 6 magnitudes and distance d= 2.9 +/- 0.4 kpc. After maximum the V-I colour index remained between 3.1 and 3.4 for 50 days, then gradually reduced as the nova became bluer with increasing age. We saw no direct evidence of dust emission although this could have contributed to the high extinction in the direction of the nova.
