May 1, 2003 observation (estimated
magnitude V=9.3)
Observatory: Castanet Tolosan (France) - IAU959
Observer: Christian
Buil
Instrument: 128 millimeters apochromaticTakahashi refractor + LORIS
spectrograph at the spectral sample of 8 A/pixel + Audine KAF-1602E CCD (bin.

Note: Spectral instrumental response correction and atmosphere transmission
for air-mass of 4.4 correction are applied (the nova is only 13° above
the horizon at the meridian).
