The Al I absorption spectrum obtained with a flash-pyrolysis technique combined with BRV source was observed in the grazing-incidence region between 140 and 650 Å. Thirty-three new lines in the range 140–160 Å were recorded. A theoretical interpretation identifies 25% of the observed lines, accounting for half the observed intensity as 2<i>p</i><sup>6</sup>3<i>s</i><sup>2</sup>3<i>p</i>-2<i>p</i><sup>5</sup>3<i>s</i><sup>2</sup>3<i>p</i>4<i>s</i> transitions.
