Abstarct:
Line emission intensities and FWHMs in the range 1175-1900Å have
been measured on high resolution IUE spectra of RR Tel taken from 1978
to 1993. The variations observed in the emission line intensities show
a rather strong correlation with the line ionization. The decrease is
of a factor larger than three and up to ten for the low-ionization
lines, and of a factor between two and three for the medium-high
ionization lines. Instead, the high ionization lines have generally
maintained their 1978 strength or have even increased it. For all
lines no variation in the FWHM has been detected. Special attention
has been paid to a very long exposure spectrum already studied by
other authors for which we present new identifications and several
comments. The presence of spurious emission features and camera
artifacts is discussed

directly measured on the spectrum, not corrected for the radial
velocity of RR Tel relative to the Sun, that has a value close
to -62km/s.
